Abstract
The application of crop growth simulation and water management models will become increasingly important in the future. They can be used to predict yield reductions due to water scarcity and allocate water to ensure profitable crop production. The objective of this research was to calibrate the AquaCrop model for common bean (Faseolus vulgaris L.) grown in temperate climates and to test whether the model can be used for different irrigation strategies to achieve high yield productivity. The model was calibrated using data obtained from two years of experimental research in the Serbian territory of the Syrmia region. There were three sowing periods/plots: I—mid April, II—end of May/beginning of June, and III—third decade of June/beginning of July; and three levels of irrigation/subplots: full irrigation (F) providing 100% of crop evapotranspiration (ETc), mild deficit irrigation (R) at 80% of ETc, and moderate deficit irrigation (S) at 60% of ETc. The results show that the AquaCrop model accurately predicts common bean yield, biomass, canopy cover, and water requirements. The statistical indices of the calibrated dataset, coefficient of determination (R2), normalized root mean square error (NRMSE), mean bias error (MBE), and Willmott agreement index (d) for yield and biomass were: 0.91, 0.99; 6.9%, 11.4%; −0.046, 1.186 and 0.9, 0.89, respectively. When testing three irrigation strategies, the model accurately predicted irrigation requirements for the full and two deficit irrigation strategies, with only 29 mm, 32 mm, and 34 mm more water than was applied for the Fs, Rs, and Ss irrigation strategy, respectively. The AquaCrop model performed well in predicting irrigated yield and can be used to estimate the yield of common bean for different sowing periods and irrigation strategies.

AB  - The objective of this study is to assess the possibility of using unmanned aerial vehicle (UAV) multispectral imagery for rapid monitoring, water stress detection and yield prediction under different sowing periods and irrigation treatments of common bean (Phaseolus vulgaris, L). The study used a two-factorial split-plot design, divided into subplots. There were three sowing periods (plots; I—mid April, II—end of May/beginning of June, III—third decade of June/beginning of July) and three levels of irrigation (subplots; full irrigation (F)—providing 100% of crop evapotranspiration (ETc), deficit irrigation (R)—providing 80% of ETc, and deficit irrigation (S) providing—60% of ETc). Canopy cover (CC), leaf area index (LAI), transpiration (T) and soil moisture (Sm) were monitored in all treatments during the growth period. A multispectral camera was mounted on a drone on seven occasions during two years of research which provided raw multispectral images. The NDVI (Normalized Difference Vegetation Index), MCARI1 (Modified Chlorophyll Absorption in Reflectance Index), NDRE (Normalized Difference Red Edge), GNDVI (Green Normalized Difference Vegetation Index) and Optimized Soil Adjusted Vegetation Index (OSAVI) were computed from the images. The results indicated that NDVI, MCARI1 and GNDVI derived from the UAV are sensitive to water stress in S treatments, while mild water stress among the R treatments could not be detected. The NDVI and MCARI1 of the II-S treatment predicted yields better (r2 = 0.65, y = 4.01 tha−1; r2 = 0.70, y = 4.28 tha−1) than of III-S (r2 = 0.012, y = 3.54 tha−1; r2 = 0.020, y = 3.7 tha−1). The use of NDVI and MCARI will be able to predict common bean yields under deficit irrigation conditions. However, remote sensing methods did not reveal pest invasion, so good yield predictions require observations in the field. Generally, a low-flying UAV proved to be useful for monitoring crop status and predicting yield and water stress in different irrigation regimes and sowing period.

AB  - This paper investigates water productivity (WP g m-2), water use efficiency (WUE kg m-3) and productive and nonproductive water of common bean (Phaseolus vulgaris L.). The experiment was set up in Stara Pazova, 40 km north of Belgrade, during 2018. Three treatments of irrigation regimes, with tree sowing periods (I – April 16, II – May 30, III – July 5) were monitored. A treatment with full irrigation (F), when 100% is covered by ETc (evapotranspiration), a treatment with deficit irrigation (R) with 80% of the ETc and a treatment with deficit irrigation (S) with 60% of ETc were applied in each sowing period. An automatic weather station was set up adjacent to the experimental plots. Reference evapotranspiration (ETo) was estimated with the FAO Penman-Monteith equation using daily data obtained from the station. Crop evapotranspiration (ETc) was calculated as the product of ETo and the dual crop coefficient. The WP values were uniform in all treatments in the I sowing period (15.66-15.82 g-2), whereas WUE values ranged from 1.31 kg m-3 (S) to 1.64 kg m-3 (F). In the II sowing period, the WP and WUE varied most, and were the highest in the F treatment (15.54 g-2, 1.58 kg m-3), slightly lower in the R treatment (13.92 g-2, 1.40 kg m-3), and the lowest values were recorded in the S treatment (12.52 g-2, 1.25 kg m-3). In the III sowing period, the highest WP and WUE were in the R treatment (12.24 g-2, 1.57 kg m-3), followed by the F treatment (14.12 g-2, 1.43 kg m-3), whereas the lowest values were observed in the S treatment (13.72 g-2, 1.27 kg m-3). The least unproductive water use was observed in the fully irrigated treatment during the I sowing period (13.46%) and the highest one in III treatment (26.30%).

AB  - INTRODUCTION and OBJECTIVES: Remote sensing is the process of detecting and monitoring the physical characteristics of an area by measuring its reflected and emitted radiation at a distance, and in a narrower sense includes the analysis and interpretation of various images of parts of the Earth's surface. The application of satellite images with modern technology and software is possible in all phases of research of various natural phenomena, and their analysis are carried out by computer-aided and visual procedures. The aim of this research is to present the basic aspects of remote sensing and modern technologies in assessing the water supply of natural grasslands, as well as the presentation of possibility for faster data collection while reducing costs, and easier understanding of the whole research area.
MATERIAL and METHOD: The trial was set on March 22nd of 2022 on a natural grassland in the village of Mitrovo polje on the mountain Goč (43° 30′ 22′ N latitude, 20° 52′ 26′ E longitude, 700 m a.s.l.) in the Aleksandrovac municipality. Disturbed and undisturbed soil samples were collected to determine soil texture, soil water retention characteristics and soil chemical properties. Continuous measurement of soil moisture was performed with TDR probes in three replicates and sensors for monitoring soil temperature were installed. The satellite images (SENTINEL 2) with a resolution 10 m, in a time interval of about a week, created in relatively clear weather (cloudiness <30%), starting from March 22 to May 21st were used,
while soil moisture data were collected on a daily basis. Data on precipitation and air temperature for the observed period were taken from the Agrosens portal. The supply of natural grassland with water and assessment of soil moisture are determined by the index of normalized difference vegetation index (NDVI), as the most applicable vegetation index. NDVI is defined as the ratio of differences between individual values of reflective wavelengths of near red and red radiation spectrum and their sum. Furthermore, for the
analysis are also used MSAVI2 index, which is mainly used to analyse plant growth, estimate grass yield, monitor drought and soil erosion, and the optimized soil-adapted vegetation index (OSAVI), which is more sensitive to vegetation. The analysis of remotely sensed images of the investigated area and statistical analysis were conducted using QGIS tools.
RESULTS and CONCLUSIONS: The results of the research show that from the beginning of grassland growth, the soil moisture ranged from 39% to 57%, which indicates that the lawn was well supplied with water. Water consumption was low at initial stage of grass growth. Soil water content at that period was high due to subsurface inflow coming from the higher parts of the terrain. The values of the NDVI index varied from 0.16 to 0.47, while the values for the MSAVI2 and OSAVI index ranged from 0.59-0.73 and
0.24-0.63, respectively. Lower index values at the beginning of the observed period (<0.16, <0.32, <0.30 for NDVI, MSAVI2 OSAVI, respectively) indicate a lack of green biomass. As the growth of natural grass increased, so do the values of all indices. Nevertheless, the obtained results show the changes of vegetation indices with the change of soil moisture, i.e. the values of the index increase due to the increase of soil
moisture after precipitation and vice versa, which leads us to the conclusion that the application of remote sensing indices can be successfull for the estimate of different vegetation conditions, detection ofsoil moisture and biomass assessment.

abstract = "INTRODUCTION and OBJECTIVES: Remote sensing is the process of detecting and monitoring the physical characteristics of an area by measuring its reflected and emitted radiation at a distance, and in a narrower sense includes the analysis and interpretation of various images of parts of the Earth's surface. The application of satellite images with modern technology and software is possible in all phases of research of various natural phenomena, and their analysis are carried out by computer-aided and visual procedures. The aim of this research is to present the basic aspects of remote sensing and modern technologies in assessing the water supply of natural grasslands, as well as the presentation of possibility for faster data collection while reducing costs, and easier understanding of the whole research area.
MATERIAL and METHOD: The trial was set on March 22nd of 2022 on a natural grassland in the village of Mitrovo polje on the mountain Goč (43° 30′ 22′ N latitude, 20° 52′ 26′ E longitude, 700 m a.s.l.) in the Aleksandrovac municipality. Disturbed and undisturbed soil samples were collected to determine soil texture, soil water retention characteristics and soil chemical properties. Continuous measurement of soil moisture was performed with TDR probes in three replicates and sensors for monitoring soil temperature were installed. The satellite images (SENTINEL 2) with a resolution 10 m, in a time interval of about a week, created in relatively clear weather (cloudiness <30%), starting from March 22 to May 21st were used,
while soil moisture data were collected on a daily basis. Data on precipitation and air temperature for the observed period were taken from the Agrosens portal. The supply of natural grassland with water and assessment of soil moisture are determined by the index of normalized difference vegetation index (NDVI), as the most applicable vegetation index. NDVI is defined as the ratio of differences between individual values of reflective wavelengths of near red and red radiation spectrum and their sum. Furthermore, for the
analysis are also used MSAVI2 index, which is mainly used to analyse plant growth, estimate grass yield, monitor drought and soil erosion, and the optimized soil-adapted vegetation index (OSAVI), which is more sensitive to vegetation. The analysis of remotely sensed images of the investigated area and statistical analysis were conducted using QGIS tools.
RESULTS and CONCLUSIONS: The results of the research show that from the beginning of grassland growth, the soil moisture ranged from 39% to 57%, which indicates that the lawn was well supplied with water. Water consumption was low at initial stage of grass growth. Soil water content at that period was high due to subsurface inflow coming from the higher parts of the terrain. The values of the NDVI index varied from 0.16 to 0.47, while the values for the MSAVI2 and OSAVI index ranged from 0.59-0.73 and
0.24-0.63, respectively. Lower index values at the beginning of the observed period (<0.16, <0.32, <0.30 for NDVI, MSAVI2 OSAVI, respectively) indicate a lack of green biomass. As the growth of natural grass increased, so do the values of all indices. Nevertheless, the obtained results show the changes of vegetation indices with the change of soil moisture, i.e. the values of the index increase due to the increase of soil
moisture after precipitation and vice versa, which leads us to the conclusion that the application of remote sensing indices can be successfull for the estimate of different vegetation conditions, detection ofsoil moisture and biomass assessment.",

AB  - Current climate conditions are often characterized by frequent water shortage during
periods when plants are most sensitive to drought stress. Soil moisture plays a key role in
pedogenic processes as well as in supplying plants with water. Therefore, it is necessary to
determine crop water requirements for the irrigaton systems design and to organize
adequate irrigation scheduling. The International Commission on Irrigation & Drainage
(ICID) and the Food and Agriculture Organization of the UN (FAO) deem the PenmanMonteith method (FAO56-PM) as the most suitable for estimating reference
evapotranspiration (ETO). Reference evapotranspiration depends on climate parameters
such as air temperature and humidity, wind speed, and net radiation but also on
geographical factors which describe the position of a certain site – latitude and elevation.
However, due to the lack of climate data, alternative methods for calculating
evapotranspiration in specific areas have been developed. This research aims to assess the
possibility for the application of several ETo methods in the climate conditions of West,
Central, Eastern, and Southern Serbia. Hargreaves, adjusted Hargreaves, Turc, and JensenHaise method were compared with the Penman-Monteith which was the referent method in
this study. The meteorological data used in this research were monthly data (2000-2019)
collected from 17 representative meteorological stations at a district scale. The methods
were compared using mean absolute error (MAE). Turc and the adjusted Hargreaves
method showed the lowest deviation from the reference (MAE=0.08 mm·day-1
, 0.14
mm·day-1
respectfully), while the Hargreaves method had shown the highest deviation
(MAE=0.74 mm·day-1
). Generally, the lowest deviation was obtained for the Bor, Mačva,
and Kolubara districts (0.23 mm·day-1
, 0.26 mm·day-1
and 0.29 mm·day-1
respectively).
Turc method had shown the lowest deviation in the Toplica district, while Hargreaves
deviated the most. The results of the research indicate that the adjusted Hargreaves and
Turc methods can be used to calculate ETo in case of missing data. The adjusted
Hargreaves is the most reliable in almost all districts, although it utilizes only air
temperature data.

AB  - Throughout history, floods have played one of the most important roles in soil formation,
maintenance and modification of soil fertility. Flooding of rivers left mud full of organic
matter in the fields, salts were washed out of the soil, and a large amount of water was
retained in the soil profile. Urbanization on the banks of rivers, regulation of water flow,
and construction of dams for flood control narrowed river beds and increased hydraulic
flow, resulting in greater concentration of flood waves during floods and shortened flood
control times. Since the beginning of the 21st century, numerous large floods have
occurred across Europe. Various climate models suggest an increase in the frequency and
intensity of future flood events. Dams were built to accommodate flood waves with a
return period of 50 years on smaller watercourses and 100 years on large rivers. Floods
with higher return periods may or may not occur at all. In this respect, dams are no
guarantee that towns and agricultural land can be successfully protected from flooding, so
their enhancement is questionable. In recent decades, there has been extensive debate about
the use of agricultural land for flood protection of cities and industrial areas, about the cost
of land and agriculture. Since private property is involved in both cases, a compromise
solution should be found that satisfies all parties. The main theme of the COST project
LAND4FLOOD is to consider all aspects of flood risk management and land management,
such as.: geographical, hydrological and hydraulic, ecological (soil pollution, compaction,
water retention, ecological services, habitat restoration), agricultural (agricultural
development in the area reserved for temporary water retention), economic (how to
compensate damages or provide incentives for flood retention, public subsidies), public
participation (how to ensure the participation of landowners), property rights issues (how
to allow temporary flood retention and what does it mean for agricultural use) and
sociological. The aim of this paper is to present some reflections on flood risk management
and its implications for land and agricultural development in the EU, as well as some
considerations on the implementation of the NBS in Serbia from the perspective of flood
protection, land protection and agricultural development.

AB  - The catchment of the Toplica River, situated in an underdeveloped region of southern Serbia, is studied to examine the potential impact of climate change on the hydrologic regime of mountainous catchments. The study projects precipitation (P), air temperature (T), potential evapotranspiration (PET), and discharge (Q) in the entire catchment, as well as groundwater level (GWL) variation in the lowland part of the catchment, according to scenarios RCP4.5 and RCP8.5. Projections of P and T are based on the results of a multimodel ensemble of seven regional climate models from the EURO-CORDEX project. Runoff is simulated by a calibrated HBV-light model. The correlation between GWL and river discharge was modeled by soft computing techniques of artificial neural networks (ANN). The projections pertain to the period from 2021 to 2100. The Mann-Kendall trend test is used to check for a trend and its statistical significance, and the Mann-Whitney test to examine the statistical significance of a change in the mean ensemble median of time-series for the near future (2021-2050) and distant future (2071-2100), relative to the reference period (1971-2000). No notable changes are expected on an annual scale in the study area. However, the results show that the current non-uniformity of the monthly water distribution is growing. In the winter months at the end of the century, in RCP8.5, P and T are expected to increase, as is Q. Groundwater responds to increased river discharges by reduced depths to groundwater (increased GWL). A higher Q increases the flood risk in the winter months. In the warm season, RCP8.5 predicts a decrease in Q and increase in the depth to groundwater in the distant future. Reduced quantities of water in the warm period might have an adverse effect on drinking water supply, agriculture, hydropower, fisheries, ecology, and tourism in the study area.

AB  - Considering the already observed trends of increasing air temperatures, changes in precipitation regimes, and extension of the growing season, as well as predictions that climate conditions in Serbia will deteriorate and the risks to farming will increase, the objective of this research is to assess the vulnerability of agriculture in Serbia to climate change, based on farmers' perceptions. A team of experts in all areas of agriculture and soil and water management compiled a questionnaire for a semi-open online survey. The snowball sampling approach was followed, relying on personal contacts and social media. In total, 141 farmers responded to the questionnaire. The data were evaluated using descriptive statistics. The differences by region, activity and topography were tested by ANOVA and Student's t-test. The feedback was used to assess the damages sustained by farmers due to climate change and reduced revenues in their respective areas of agricultural activity. Certain positive effects of climate change were also identified. A need for training in climate change impact mitigation is noted. The collected data were analyzed by descriptive statistics. The surveyed farmers believe that the most important effects of climate change were periods of extreme high temperature, droughts, late spring frost, and hail. Climate change seems to be reducing yields, facilitating the appearance of new diseases and pests, and causing a lower tolerance to existing diseases and pests. Farmers expressed considerable interest in climate change impact adaptation and mitigation training.
AB  - U skladu sa već osmotrenim trendovima povećanja temperature vazduha, izmenjenog režima padavina i produžetka vegetacione sezone, kao i sa predviđanjima da će se klimatski uslovi u Srbiji izrazito pogoršavati, a rizici u poljoprivrednoj proizvodnji povećavati, cilj ovog rada je da se proceni ranjivost poljoprivredne proizvodnje u Srbiji pod uticajem klimatskih promena na osnovu percepcije poljoprivrednika. Tim eksperata iz svih oblasti poljoprivrede i upravljanja vodama i zemljištem, sastavio je pitanja za onlajn anketu, poluotvorenog tipa. Prikupljanje podataka je vršeno putem interneta, uglavnom se oslanjajući na društvene mreže. Na upitnik je odgovorio ukupno 141 ispitanik. Analiza podataka je vršena putem deskriptivne statistike, a primenjena je analiza glavnih komponenti (PCA) sa Varimax rotacijom.

abstract = "Considering the already observed trends of increasing air temperatures, changes in precipitation regimes, and extension of the growing season, as well as predictions that climate conditions in Serbia will deteriorate and the risks to farming will increase, the objective of this research is to assess the vulnerability of agriculture in Serbia to climate change, based on farmers' perceptions. A team of experts in all areas of agriculture and soil and water management compiled a questionnaire for a semi-open online survey. The snowball sampling approach was followed, relying on personal contacts and social media. In total, 141 farmers responded to the questionnaire. The data were evaluated using descriptive statistics. The differences by region, activity and topography were tested by ANOVA and Student's t-test. The feedback was used to assess the damages sustained by farmers due to climate change and reduced revenues in their respective areas of agricultural activity. Certain positive effects of climate change were also identified. A need for training in climate change impact mitigation is noted. The collected data were analyzed by descriptive statistics. The surveyed farmers believe that the most important effects of climate change were periods of extreme high temperature, droughts, late spring frost, and hail. Climate change seems to be reducing yields, facilitating the appearance of new diseases and pests, and causing a lower tolerance to existing diseases and pests. Farmers expressed considerable interest in climate change impact adaptation and mitigation training., U skladu sa već osmotrenim trendovima povećanja temperature vazduha, izmenjenog režima padavina i produžetka vegetacione sezone, kao i sa predviđanjima da će se klimatski uslovi u Srbiji izrazito pogoršavati, a rizici u poljoprivrednoj proizvodnji povećavati, cilj ovog rada je da se proceni ranjivost poljoprivredne proizvodnje u Srbiji pod uticajem klimatskih promena na osnovu percepcije poljoprivrednika. Tim eksperata iz svih oblasti poljoprivrede i upravljanja vodama i zemljištem, sastavio je pitanja za onlajn anketu, poluotvorenog tipa. Prikupljanje podataka je vršeno putem interneta, uglavnom se oslanjajući na društvene mreže. Na upitnik je odgovorio ukupno 141 ispitanik. Analiza podataka je vršena putem deskriptivne statistike, a primenjena je analiza glavnih komponenti (PCA) sa Varimax rotacijom. Uočena su dva faktora: (i) uticaj klimatskih promena na rizike u poljoprivredi, i (ii) šteta izazvana klimatskim promenama.

AB  - Land use change in all river basins leads to changes in hydrologic response, soil erosion, and sediment dynamics characteristics. Those changes are often viewed as the main cause of accelerated erosion rates. We studied the impact of land use changes on soil erosion processes in one of the watersheds in Montenegro: the Miocki Potok, using this watershed as a pilot river basin for this area. We simulated responses of soil erosion processes by using a process-oriented soil erosion Intensity of Erosion and Outflow (IntErO) model, with different settings of land use for the years 1970, 1980, 1990, 2000, 2010, and 2020. The model provides fast, effective, and affordable insight into the effects of land use change on soil erosion processes. Testing of the applied procedures was important for the further establishment of watershed management methodologies at the national level, for the other 300 river basins of Montenegro. For the current state of land use, calculated peak discharge for the Miocki Potok was 364 m3 s−1 (2020)–372 m3 s−1 (1970) for the incidence of 100 years, and there is a possibility for large flood waves to appear in the studied basin. Real soil losses, Gyear, were calculated at 13680 m3 year−1 (2020) and specific 333 m3 km−2 year−1 (2020). A Z coefficient value of 0.439 (2020) indicated that the river basin belongs to destruction category III. The strength of the erosion process was medium, and according to the erosion type, it was mixed erosion. According to our analysis, the land use changes in the last 50 years influenced a decrease in the soil erosion intensity for 14% in the Miocki Potok River Basin. Further studies should be focused on the detailed analysis of the land use changes trends with the other river basins at the national level, closely following responses of soil erosion to the changed land use structure, and effects of plant-and-soil interaction on soil erosion and sediment dynamics.

AB  - The effect of different irrigation regimes and the application of kaolin on the canopy temperatures of sweet pepper (Capsicum annuum L.) and tomato (Lycopersicon esculentwn MilL), determined by a nondestructive imaging method, is discussed in the paper. The research was conducted in an open field on carbonate chernozem soil at Stara Pazova (40 km north of Belgrade, Serbia), over a period of three years (2011, 2012 and 2013). The setup was a two-factorial, completely random block system, with three replications. The first factor was the irrigation regime and the second the application of kaolin. The experimental pepper plants were subjected to thre different irrigation regimes: a) full irrigation (F), covering 100% of ETc (cultivar's evapotranspiration rate); b) deficit irrigation at 80% of ETc (R1); and deficit irrigation at 70% of ETc (R2). Two different irrigation regimes were monitored in the case of tomato: full irrigation (F), covering 100% of ETc, and b) deficit irrigation at 50% of ETc (D). The kaolin treatments of both crops were: a) control without kaolin (C) and 5% kaolin suspension (K). The results of this research indicated that the irrigation regime had a very significant effect on the temperature of pepper and tomato; the higher the level of irrigation, the lower the temperature. The dual-effect of kaolin impacted the heat balance of the plants.

AB  - The paper presents the results of leaf temperature measurements in a raspberries orchard, recorded by a thermal imaging camera. The raspberry orchard was planted in spring 2014, while the experiment was set up in spring 2015, i.e., the first yielding year. The orchard is located in the south-western part of Republic of Serbia (Ivanjica region). This mountain region is characterized by limited water resources. During the experiment, three irrigation treatments were applied: deficit irrigation (N), deficit irrigation with hay mulch (NM), and rain-fed condition (NN). Leaf temperature was measured with a FLIR T335 thermal camera, six times during harvesting. In total 30 measurements were carried out on plants of each treatment and the average leaf temperatures calculated. In the N and NM treatments, soil water content was continuously measured by TDR sensors. Weather data were automatically recorded near the experimental field. Results indicated that plants in the NN treatment were warmest, followed by those in the N treatment. Leaf temperatures for plants of the NN treatment were mostly higher than air temperature, while in the N and NM treatments higher values were only observed in one of the six measurements. However, soil moisture contents reflected the trend observed for leaf temperature. Soil moisture content in the NM treatment was the closest to field capacity, while that in NN treatment was close to the wilting point. According to the presented results, mulch has a positive impact on irrigation water saving, which is very important for this region. Difference in air and leaf temperature vs. vapour pressure deficit was linearly related. Average CWSI for N, NM and NN treatments indicated clear differences between treatments.

AB  - Limited water resources, an increase in water demand and a changing climate triggered the development of new concepts for assessment of water demand and water consumption locally and globally. The newest concepts that successfully tackle this issue are water footprint and virtual water trade. Aims of this study are: (1) to define specific water demand for the most important agricultural products in the international trade of the Republic of Serbia, (2) to assess possibilities of an increase in water productivity for those products, and (3) to assess sustainability of water resources in Serbia, based on the ratio of import/export during virtual water trade. Specific water demand for wheat, maize, sunflower, sugar beet and soya bean has been calculated and compared with specific water demand in other countries. Results prove that water productivity can be improved by, for example, using other varieties of crops or modifying cultivation technology. The ratio of imported/exported virtual water quantities for the periods 1995-1999 and 2010- 2013 in Serbia shows that more water was exported than imported. Sustainability of water resources in Serbia will not be endangered even if the export of agricultural products is increased.
AB  - Ograničeni vodni resursi, rastući zahtevi za vodom i sve nepovoljniji klimatski uslovi doveli su do razvoja novih koncepata, sa ciljem procene potražnje i potrošnje vode na lokalnom i globalnom nivou. Koncepti koji se u novije vreme koriste pri rešavanju ovakvih problema su 'vodni otisak' i 'virtuelna trgovina vodom'. Ciljevi ovog rada su: (1) da se odrede specifični zahtevi za vodom najvažnijih poljoprivrednih proizvoda u procesu međunarodne trgovine Srbije, (2) da se oceni mogućnost povećanja produktivnosti vode pri proizvodnji tih proizvoda i (3) da se proceni održivost vodnih resursa Srbije, na osnovu odnosa vode koju Srbija uvozi/izvozi tokom 'virtuelne trgovine vodom'. Izračunavanjem specifične potrošnje vode za pšenicu, kukuruz, suncokret, šećernu repu i soju i poređenjem sa specifičnom potrošnjom vode ovih kultura u drugim zemljama, utvrđeno je da postoji prostor da se unapredi korišćenje vode, npr. podešavanjem sortimenta ili promenama u tehnologiji gajenja. Na osnovu odnosa izračunatih izvezenih i uvezenih virtuelnih količina vode za period 1995-1999. godine i 2010-2013. godine, može se zaključiti Srbija izvozi više vode nego što uvozi. Čak i sa dodatnim porastom izvoza poljoprivrednih proizvoda neće doći do narušavanja vodne održivosti Srbije.

Ciljevi ovog rada su: (1) da se odrede specifični zahtevi za vodom najvažnijih poljoprivrednih proizvoda u procesu međunarodne trgovine Srbije, (2) da se oceni mogućnost povećanja produktivnosti vode pri proizvodnji tih proizvoda i (3) da se proceni održivost vodnih resursa Srbije, na osnovu odnosa vode koju Srbija uvozi/izvozi tokom 'virtuelne trgovine vodom'. Izračunavanjem specifične potrošnje vode za pšenicu, kukuruz, suncokret, šećernu repu i soju i poređenjem sa specifičnom potrošnjom vode ovih kultura u drugim zemljama, utvrđeno je da postoji prostor da se unapredi korišćenje vode, npr. podešavanjem sortimenta ili promenama u tehnologiji gajenja. Na osnovu odnosa izračunatih izvezenih i uvezenih virtuelnih količina vode za period 1995-1999. godine i 2010-2013. godine, može se zaključiti Srbija izvozi više vode nego što uvozi. Čak i sa dodatnim porastom izvoza poljoprivrednih proizvoda neće doći do narušavanja vodne održivosti Srbije.",

AB  - The applicability of the FAO AquaCrop model to simulate sweet pepper growth with and without plastic film mulching under different water supply and weather conditions is assessed. Pepper yield and biomass are simulated using the results of a two-year (2012 and 2013) field experiment conducted in Stara Pazova and a three-year (2011, 2012 and 2013) field experiment in Sombor, both in Serbia. The year 2012 was much warmer and drier than the two other years. At the Stara Pazova site, black plastic mulch was used and three different irrigation treatments applied: 1) full irrigation (F), at 100% of ETc (crop evapotranspiration); 2) deficit irrigation (R), at 80% of ETc; and 3) deficit irrigation (S), at 70% of ETc. In Sombor, only full irrigation (F*) was applied and there was no mulching. Two different cultivars (cv. Elephant Ear and Misina) were grown in Stara Pazova and Sombor, respectively. The model was calibrated using data from the F-treatment in 2012 at Stara Pazova and F*-treatment in 2011 at Sombor, given that the highest yields were recorded in these two cases. The difference between the measured and simulated values was 2.9% and 7.5% for yield and 7.6% and -14.3% for biomass, in Stara Pazova and Sombor, respectively. The calibration results showed a very good agreement between the measured and simulated values. The deviation of simulated yields from the measured values in the validation data set depended on weather and soil conditions. Namely, the match was very good in the case of well-watered pepper grown without plastic film mulching in the average year at Sombor (1.2%), and was the worst in the extremely warm year (-45.2%). Similar differences were noted in biomass. Based on statistical indicators, the coefficient of determination (R-2) of pepper yield at Stara Pazova and Sombor was 0.61 and 1.00 and the Willmott index of agreement (d), 0.79 and 0.89, respectively. Thus the AquaCrop model simulates the yield of pepper grown with and without plastic film mulching quite well. Biomass simulations resulted in slightly lower values of R2 and d. The AquaCrop model can also predict the amount of water needed for pepper grown with and without black plastic mulch.

AB  - Modern agriculture is faced with two tasks: (1) to produce enough food for a growing global population, and (2) to ensure satisfactory crop quality while using water resources efficiently. A study of the effect of kaolin on the yield, quality and water use efficiency of tomato (Lycopersicon esculentum Mill.), grown under different irrigation regimes, is reported in the paper. The research was conducted in an open field with carbonate chernozem soil, at Stara Pazova (40 km north of Belgrade, Serbia). It lasted for three years (2011, 2012, and 2013). The experimental setup was a two-factorial, completely random block system, with three replications. The first factor was the irrigation regime and the second the application of kaolin. Two irrigation treatments were studied: (a) full irrigation (F), covering 100% of ETc (crop evapotranspiration), and (b) deficit irrigation (D) at 50% of ETc. The kaolin treatments were: (a) control treatment, without kaolin (C) and treatment with a 5% suspension of kaolin (K). On average, the highest fresh tomato fruit yields were achieved under full irrigation, with kaolin (FK) (21.0 kg m(-2)). The FK treatment also resulted in the greatest dry weight of the fruits (1.1 kg m(-2)). The average fruit weight was rather uniform and ranged from 71.7 g with DC to 75.4 g with DK. The average sugar and lycopene content was quite uniform over the study period, while the irrigation regime had a significant effect on the average organic acid content and total antioxidant activity. Deficit irrigation treatments resulted in a higher organic acid content and higher total antioxidant activity than full irrigation. The application of kaolin had a greater effect of the water use efficiency of tomato than the irrigation treatment.

AB  - The formation of a river channel stream profile in natural conditions is a long process that lasts for hundreds of years. Research at experimental sections of streams is necessary to discover the initial phases of river beds morphological development. In order to achieve this, this study focused on the period after regulatory earth works. From this initial period, the earthy regulated channel is left to the natural processes of morphological formation. This paper presents the research on morphological changes in the Pestan River (H min, 44 degrees 26'08.4" N 20 degrees 15'23.2" E) from 1978 to 2013, after the regulatory works. One of the possible reasons for permanent morphological changes is reaching the balance between transport and disposition of river sediment, and transport capacity of the stream. The experimental stream reach is located upstream from the mouth of the Pestan into the Kolubara. The goal of the research was to determine the causes of steady morphological changes of the regulated channel, from the initial phase, after the regulatory works, until today.

AB  - There are conflicting opinions about the need to fertilize Miscanthus and, also, the question has been raised whether Miscanthus should be irrigated, especially if water resources are limited. Crop growth modeling can help answer such questions. In this article the FAO AquaCrop water-driven model was selected to simulate Miscanthus biomass under different nutrient and water supply conditions. The article reports the outcomes of 6-year experiments with Miscanthus on two locations in Serbia: Zemun, where three fertilizer treatments were applied (N-l - 100kgha(-1), N-opt 50kgha(-1) and N-f nonfertilized), and Ralja, where only N-l 100kgha(-1) was applied. Model calibration focused on the measured data (root depth, crop phenology, and the above-ground biomass by year of growth. Calibration results showed a very good match between measured and simulated values. The largest and only significant difference was noted in 2008, when the crop was establishing and exhibited uneven radication. The simulation results for the next 5years showed a variance from -4 to 5.7%, believed to be a very good match. A high coefficient of determination (R-2=0.995) and high Willmott index of agreement (0.998) were also indicative of a good match between simulated and recorded biomass yields. The measured and simulated results for validated datasets at both locations were good. The average RMSE was 2.89 Mgha(-1); when compared to the deviations noted at the test site itself, it was apparent that they were smaller in all the years of research except the first year. The index of agreement was 0.97 and the coefficient of determination R-2 0.947. The AquaCrop model can be used with a high degree of reliability in strategic planning of Miscanthus cultivation in new areas, under different nutrient and water supply and local weather and soil conditions.

AB  - The present paper reports research that focused on the effect of kaolin on the yield, quality and water use efficiency of the sweet pepper Capsicum annuum L, grown under different irrigation regimes. The research was conducted in an open field with carbonate chernozem soil, at Stara Pazova (40 km north of Belgrade, Serbia). It lasted for three years (2011, 2012, and 2013). Three irrigation regimes and two kaolin treatments were compared. The irrigation regimes were: (i) full irrigation (F) ensuring 100% of crop evapotranspiration (ETc), (ii) deficit irrigation at 80% ETc (R1), and (iii) deficit irrigation at 70% ETc (R2). The kaolin treatments were: (i) control without kaolin (C) and (ii) treatment with kaolin application (K). The setup was a two-factorial, completely random block system, with three replications. The first factor was the irrigation regime and the second kaolin application. On average, the highest fresh sweet pepper yields were achieved under full irrigation (10 kg m(-2)). Also, FC and FK treatments resulted in the highest first-class, second-class and first + second class yields. On average, the lowest percentage of sunburn was noted in the case of the FK treatment (10%), and the highest with the R2C treatment (about 27%). The sugar content of the pepper was quite consistent, while the organic acid content varied from 15.0 mLg(-1) with R1C to 18.7 mLg(-1) with FK. The application of kaolin and the irrigation regime did not have a statistically significant effect on the antioxidant activity of the pepper and ranged from 5538.4 to 6447.4 p.mol TU g(-1). The highest yield water use efficiency (yWUE) of first-class and first+second class yields was recorded with the FC, FK and RIC treatments. Throughout the study period, yWUE levels of the second-class yields, and of the total yield, were rather uniform, regardless of the type of treatment.

The irrigation regimes were: (i) full irrigation (F) ensuring 100% of crop evapotranspiration (ETc), (ii) deficit irrigation at 80% ETc (R1), and (iii) deficit irrigation at 70% ETc (R2). The kaolin treatments were: (i) control without kaolin (C) and (ii) treatment with kaolin application (K). The setup was a two-factorial, completely random block system, with three replications. The first factor was the irrigation regime and the second kaolin application. On average, the highest fresh sweet pepper yields were achieved under full irrigation (10 kg m(-2)). Also, FC and FK treatments resulted in the highest first-class, second-class and first + second class yields. On average, the lowest percentage of sunburn was noted in the case of the FK treatment (10%), and the highest with the R2C treatment (about 27%). The sugar content of the pepper was quite consistent, while the organic acid content varied from 15.0 mLg(-1) with R1C to 18.7 mLg(-1) with FK. The application of kaolin and the irrigation regime did not have a statistically significant effect on the antioxidant activity of the pepper and ranged from 5538.4 to 6447.4 p.mol TU g(-1). The highest yield water use efficiency (yWUE) of first-class and first+second class yields was recorded with the FC, FK and RIC treatments. Throughout the study period, yWUE levels of the second-class yields, and of the total yield, were rather uniform, regardless of the type of treatment.",

AB  - Water table forecasting plays an important role in the management of groundwater resources in agricultural regions where there are drainage systems in river valleys. The results presented in this paper pertain to an area along the left bank of the Danube River, in the Province of Vojvodina, which is the northern part of Serbia. Two soft computing techniques were used in this research: an adaptive neurofuzzy inference system (ANFIS) and an artificial neural network (ANN) model for one-month water table forecasts at several wells located at different distances from the river. The results suggest that both these techniques represent useful tools for modeling hydrological processes in agriculture, with similar computing and memory capabilities, such that they constitute an exceptionally good numerical framework for generating high-quality models.

AB  - This paper presents measurements of temperature of the above-ground parts of peppers plants using a thermal imager in order to determine the water regime. The experiment was set as a bifactorial block system, with three replications, in the open field on a carbonate chernozem soil in Stara Pazova (40 km North from Belgrade, Serbia). Three treatments of irrigation regimes, with and without the application of 5% kaolin suspension (Surround WP), were monitored. Kaolin (Surround WP) was applied by spraying of the part of the plant above the ground seven times during the vegetation seasons between April and September 2011. All the treatments that have been applied with kaolin have a sign K. Treatment with full irrigation (F, FK) when 100% is covered by ETc (evapotranspiration), a treatment with deficit irrigation (R, RK) with 80% of the ETc and a treatment with deficit irrigation (S, SK) with 70% of ETc. The measurements of plant temperature were carried out with an infrared camera (FLIR, T335) seven times during the vegetation season. From each treatment a sample of 15 measurements was taken and the measurements were used for determination of average temperature of the plant on every level of irrigation. Soil moisture was measured by gravimetric method in 7 day intervals, up to 0.6 m and every 0.2 meters. Temperature measurement data show that the F treatment plants were the coldest with the average temperature of 21.29 degrees C, followed by the R and S treatment with the average temperature of 21.79 degrees C and 22.26 degrees C, respectively. Average temperatures of FK, RK and SK treatments were as follows 21.58 degrees C, 22.11 degrees C and 22.47 degrees C. Plants treated with kaolin had higher temperatures on average, but for the precise conclusion more measurements are needed due to the variability of canopy temperature. Observing the values of soil moisture over all treatments, it can be assumed that kaolin has a role in reducing water consumption. It is also confirmed by CWSI (Crop Water Stress Index). Relationships of available soil water (ASW) and the CWSI show differences between all irrigation and kaolin treatments. The values of CWSI are the lowest and almost never more than zero in fully irrigated treatments (F and FK), in R and RK treatments they are slightly higher, and the highest in S and SK treatments. The values of CWSI are lower in the treatments without kaolin application. Obtained results show an effect of irrigation regime on the canopy temperature of peppers, while the influence of kaolin is small.

AB  - Climate change impact on field production may play a great role in strategic planning on soil and water resources management. Therefore, the aim of this work was to find out the impact of climate change on sugar beet yield, irrigation depth variation and water saving practices. AquaCrop model v.4.0 was used for yield and irrigation requirement estimation. Input data for future climatic parameters were obtained from EBU-POM for four scenarios A1B, A2, A1B* and A* (* >CO2), and periods of observation were first (2010-2039); second (2040-2069), and third (2070-2099). Undoubtedly, yield will not be reduced in the first period by any scenario, on the contrary, it might be increased. In the second period, yield reduction was observed in A1B i A2 scenarios, hence without the increment of CO2 in the Vojvodina region, whereas in Central Serbia, yield reduction might be expected even in scenarios of A1B and A2*. Irrigation could ensure yield increment in both regions, provided that an increase is more considerable in Central Serbia, due to lower soil water capacity. Application of optimal irrigation depth yield could be increased by up to 57-97% in Vojvodina and 77-285% in Central Serbia. Lower values are obtained in the first period and the highest in the third period. Applying deficit irrigation, water saving would reduce yield in scenario A2, otherwise to obtain high yield, irrigation depth of 300-500 mm should be ensured in Central Serbia. In the same scenario, 300-420 mm of water for irrigation is needed in Vojvodina, but its water savings could be 80-120 mm, or 20%. In scenario A1B, to obtain high yield, 80 mm could be saved in both regions.
AB  - Uticaj klimatskih promena na proizvodnju hrane je od velikog značaja za strateško planiranje upravljanja prirodnim resursima, pre svega vode i zemljišta. Stoga je cilj ovoga rada bio da se proceni kako klimatske promene mogu uticati na prinose šećerne repe, norme navodnjavanja i mogućnosti uštede vode za navodnjavanje. Za simulaciju prinosa i potreba useva za vodom korišćen je model AquaCrop i rezultati povezanog regionalnog klimatskog modela za atmosferu i okean EBU-POM za scenarija A1B, A2 za prvi period (2010-2039); drugi (2040-2069) i treći (2070-2099). U scenarijima sa oznakom A1B* i A2* su u modelu AquaCrop uzete povećane koncentracije CO2. Na područjima Vojvodine i centralne Srbije se jasno vidi da se u prvom periodu neće smanjiti prinosi ni po jednom scenariju, već se mogu očekivati i povećanja po svim varijantama gajenja šećerne repe. U drugom periodu, uočavaju se padovi prinosa u scenarijima A1B i A2 na području Vojvodine, dok se u centralnoj Srbiji može očekivati i pad prinosa u scenariju A1B kao i u scenariju A2*. Navodnjavanjem se u svim scenarijima značajno povećava prinos, s tim što je povećanje prinosa izraženije na području centralne Srbije. Ukoliko bi se koristile optimalne norme navodnjavanja prinos bi mogao da se poveća od 57-97% u Vojvodini i 77-285% u centralnoj Srbiji. Uticaj navodnjavanja na povećanje prinosa je najmanji u prvom periodu i on linearno raste u drugom i trećem periodu. U uslovima redukovanog navodnjavanja u scenariju A2, na području centralne Srbije voda bi mogla da se uštedi samo na račun pada prinosa. Za postizanje visokih prinosa, neophodno je obezbediti od 300 do 500 mm vode, a na području Vojvodine od 300 do 420 mm, s mogućnošću uštede za oko 20%. Pri scenariju A1B bi se moglo uštedeti do 80 mm na oba područja.

AB  - Over the past several decades, drought events in Serbia have become increasingly frequent. There is no temporal pattern and relatively homogeneous regions tend to exhibit varying degrees severity and non-uniform spatial distributions of drought. The impact of scarce or excessive precipitation during a specific time period largely depends on the local geography, climate, vegetation and other factors. Agriculture in Serbia is traditionally rainfed and the question is often raised, who has suffered more from drought and who should receive more subsidies. The task of the government, as the highest instance in the decision-making process, is to make such decisions based on a set of local parameters reflecting a large number of regions. The approach leading to a general decision using a series of local indicators needs to be objective and founded upon both physical observations and statistical decision-making methods. The main objective of this paper is to propose an approach to the characterization of individual areas within a region (the lowland region of Vojvodina) from a drought severity perspective during the growing season, and to then validate the procedure in areas of another region (the hilly region of Sumadija), whose characteristics differ to a large extent but which is under the administrative jurisdiction of the same legislative bodies in Serbia. The proposed approach is based on the Standardized Precipitation Index (SPI) and on statistical pattern recognition. Using SPIs derived for individual local areas, a random vector is generated to represent drought severity in the extended region, and then scattering matrices are applied to reduce dimensions and design a parametric classifier for the reduced space, leading to the final, general decision. The proposed algorithm is not subject to any geographical constraints and is not affected by the surface areas of the regions or their inter-relationships. The end result is a clear picture of the areas within the analyzed region which are influenced by local factors and, as such, representative of the analyzed region, and those that stand out as good representatives for final decision-making purposes. The procedure was implemented using SPIs from 20 meteorological stations, covering a period of 56 years.

AB  - Farming in Serbia is traditionally rainfed. Analyses show that drought events of varying severity are frequent in this region, although there is no specific pattern. There is a distinct need for an objective assessment of the impact of drought on strategic field crops, to solve the dilemma whether irrigation is required or not. For this reason, and based on available field data, the FAO AquaCrop water driven model was selected to simulate yield and irrigation water use efficiency (IWUE) for three major field crops (maize, sunflower, and sugar beet), under two scenarios: (1) natural water supply and adequate supply of nutrients, and (2) supplementary irrigation and adequate supply of nutrients. The experiments presented here were conducted between 2000 and 2007 in northern Serbia, where chernozem soil is prevalent. Data of 2003 cropping seasons were used for local calibration, whereas the remaining years for validation. Results were such that local calibration resulted in very minor changes of AquaCrop coefficients (e.g.. maize basal crop coefficient, sunflower harvest index, etc.). Simulated maize yield levels exhibited the greatest departure from measured data under irrigation conditions (-3.6 and 3.3% during an extremely dry and an extremely wet year. respectively). Simulated sunflower yield levels varied by less than 10% in 8 out of 10 comparisons. The most extreme variation was noted during the extremely wet year. The difference between simulated and measured values in the case of sugar beet was from -10.2 to 12.2%. Large differences were noted only in two or three cases, under extreme climatic conditions. Statistical indicators - root mean square error (RMSE) and index of agreement (d) - for all three crops suggested that the model can be used to highly reliably assess yield and IWUE. This conclusion was derived based on low values of RMSE and high values of d (in the case of maize and sugar beet 0.999 for both yield and IWUE, and in the case of sunflower 0.999 for yield and 0.884 for IWUE). It is noteworthy that under wet conditions, the model suggested that sunflower and sugar beer do not require irrigation, as confirmed by experimental research. These data are significant because they show that the AquaCrop model can be used in impartial decision-making and in the selection of crops to be given irrigation priority in areas where water resources are limited.

AB  - This paper proposes a procedure for decision-making regarding the extent to which a certain geographical region is affected by drought. Professional circles generally recognize the Standardized Precipitation Index (SPI) as a good indicator of a drought event. However, as a result of varying precipitation levels due to various local geographical, climatic, vegetational and other factors, this indicator is determined based on precipitation measurements and different meteorological centres within the same administrative region often generate different SPI values, even when the geographical distance between them is small. During a dry period, various local authorities, ministries of agriculture or governments have to make important decisions about, for example, declaring disasters, subsidizing farmers for certain crops, or providing financial aid to agricultural producers, based on voluminous and diverse data about local precipitation, the yield of various crops, or the condition of the soil. This paper proposes an automated methodology for such decision-making, which can be used as a support tool by decision-makers. The methodology is based on the SPI and statistical pattern recognition methods (dimension reduction and classifier design based on the desired output). The entire procedure is illustrated using Vojvodina, a region in Serbia in the southern portion of the Pannonian Plain, as a case study. The proposed algorithm is not subject to any constraints with regard to geographical locations of regions, their surface areas, or inter-relationships.
