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  - 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  - The role of hydrological models in water management is significant. One of their important applications is the development and management of water resources, including water quality and sediment transport. Semi-distributed hydrological models, such as HBV-light, provide the possibility of dividing the catchment into sub-catchments and zones according to height and type of land cover. GIS tools provide significant support to prepare input for these models. The paper presents the methodology for preparing input data, using the QGIS tool, for the HBV-light hydrological model, which is used for continuous hydrological simulations. This model transforms precipitation from the catchment into runoff. Three alternative methods are described and compared within the methodology, based on the example of the Veternica river catchment.

AB  - Potato is the most important non-grain crop in the world. Produced in a traditional way (without irrigation) in Bosnia and Herzegovina averages about 370 000 tons per year. Climate change will probably affect potato crop production, especially due to shallow rooting system. The aim of this paper is to assess the impact of climate change on the potato water requirements for the IPCC RCP 8.5 scenario. AquaCrop V6.0 model was used to estimate potato irrigation norms (In), drainage water and yield. Three distinct area were analyzed; Banja Luka, Bijeljina and Mostar. Climate data were obtained from a climate change simulation of a regional climate model NMMB. The simulation is done as a dynamical downscaling of the global model CMCC-CM over the Southeast Europe. Models are forced with IPCC RCP8.5 scenario. Four periods were analyzed; the reference period (1971-2000) and three time slices in the future: 2020s (2011-2040); 2050s (2041-2070; 2080s (2071-2100). Obtained results in three future periods were compared with referenced ones, and shown as a relative ratio. Sowing dates will be moved towards winter months in all areas. Such results will have an impact on yield increment in rainfed conditions up to 85%. Obtained data showed decrement of the In in Banja Luka and Mostar area up to 18% and 25% through the century, respectively. However, drier conditions in Bjeljina region will affect yield decline. In increment with magnitude of 70% to 34% will be expected in Bjeljina area due to lower precipitation. Thus makes irrigation very important in order to achieve genetic potential of potato. Drainage system should be implemented and/or well maintained in all areas.

AB  - A probabilistic crop forecast based on ensembles of crop model output estimates, presented here, offers an ensemble of possible realizations and probabilistic forecasts of green water components, crop yield and green water footprints (WFs) on seasonal scales for selected summer crops. The present paper presents results of an ongoing study related to the application of ensemble forecasting concepts in crop production. Seasonal forecasting of crop water use indicators (evapotranspiration (ET), water productivity, green WF) and yield of rainfed summer crops (maize, spring barley and sunflower), was performed using the AquaCrop model and ensemble weather forecast, provided by The European Centre for Medium-range Weather Forecast. The ensemble of estimates obtained was tested with observation-based simulations to assess the ability of seasonal weather forecasts to ensure that accuracy of the simulation results was the same as for those obtained using observed weather data. Best results are obtained for ensemble forecast for yield, ET, water productivity and green WF for sunflower in Novi Sad (Serbia) and maize in Gross-Enzersdorf (Austria) - average root mean square error (2006-2014) was  lt 10% of observation-based values of selected variables. For variables yielding a probability distribution, capacity to reflect the distribution from which their outcomes will be drawn was tested using an Ignorance score. Average Ignorance score, for all locations, crops and variables varied from 1.49 (spring barley ET in Gross-Enzersdorf) to 3.35 (sunflower water productivity in Gross-Enzersdorf).

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  - Serbia is situated at Balkan Peninsula, and currently majority of the territory is under warm temperate fully humid climate type with warm summers (Cfb type, according to Koppen-Geiger Climate Classification). Observed changes in climate conditions since 1961 until present time show significant increase in temperature change and change in precipitation patterns. Disturbances in heat conditions, which are recorded to affect human health, agricultural production and forest ecosystem, are priority in climate change analysis and application in adaptation planning. Future change analysis show accelerated increase of temperature by the end of the 21st century, which proves the needs for immediate measures for mitigation of negative impacts. Temperature increase averaged over the territory of Serbia is 1.2 degrees C for the period 1996-2015 with respect to the period 1961-1980, with highest increase of maximum daily temperature during the summer season, 2.2 degrees C. Using high resolution multi-model ensemble approach for analysis of the future changes with respect to the base period 1986-2005, in compliance with Intergovernmental Panel on Climate Change (IPCC) fifth assessment report (ARS), it is estimated that temperature may increase by 1.9 degrees C according to Representative Concentration Pathway 4.5 (RCP4.5) scenario and by 4.4 degrees C according to RCP8.5 by the end of the century. Spatial distribution of temperature increase, intensification of high precipitation events and decrease of summer precipitation, show intrusion of subtropical climate over the Serbia and increase of high temperature and high precipitation risks. Results presented in this paper, using high-resolution multi-model ensemble approach, provide climate change information for short term to long term planning in different sectors of economy and preservation of human health and environment.

AB  - In order to calculate water deficit of agricultural crops, it is necessary to have an insight into the evapotranspiration process. As for evaluation of reference evapotranspiration, the Penman-Monteith (FAO56-PM) method, suggested by The International Commission on Irrigation and Drainage (ICID) and Food and Agriculture Organization of the United Nations (FAO), requires several climate parameters, which are often unavailable. Thus, in this paper, the methods for computing ETo, which use limited weather data, were tested and then compared to FAO56-PM. The selected methods were those most often used as the replacement for FAO56-PM: Hargreaves, adjusted Hargreaves, Copais, Turc, Priestley-Taylor, Makkink and Hamon. ETo was calculated at the daily and average monthly levels, for the 2010 2013 period, using data from the following meteorological stations: Niš, Belgrade, Novi Sad, Loznica, Valjevo, Zlatibor, Ćuprija and Kikinda. Special importance was given to the vegetation period during the dry season due to the application of irrigation. The comparison of methods was based on statistical analysis, using parameters: MXE, MAE, RMSD, ARMSD, WRMSD, b and R2. The highest rate of matching FAO-PM at the average monthly level, as well as during the 2012 growing season, was shown by Copais, Turc and Priestley-Taylor methods, thus these methods may be recommended as the replacement for FAO-PM under climate conditions of Serbia. In case only temperature data are available, the results of this research justify the use of the adjusted Hargreaves equation to calculate ETo for the vegetation period.

Zato su u ovom radu testirane metode za proračun ETo koje koriste manji broj podataka i upoređivane sa FAO56-PM.

Poseban značaj dat je vegetacionom periodu tokom sušne godine, interesantnom sa aspekta primene navodnjavanja. Upoređivanje metoda rađeno je na osnovu statističke analize, pri čemu su korišćeni parametri: MXE, MAE, RMSD, ARMSD, WRMSD, b i R2. Najbolje slaganje sa metodom FAO-PM na prosečnom mesečnom nivou, kao i u letnjem periodu 2012. godine, pokazale su metode Copais, Turc i Priestley-Taylor, pa se one mogu preporučiti kao zamena za metodu FAO56-PM, u našim klimatskim uslovima. Ukoliko se raspolaže samo podacima o temperaturi vazduha, rezultati dobijeni u ovom istraživanju pokazuju opravdanost upotrebe modifikovane metode Hargreaves za proračun ETo u toku vegetacionog perioda.

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  - 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  - Given that the optimal sowing rate and inter-row spacing of Italian ryegrass raised for seed have not been determined, the objective of this research was to assess the effect of crop density on biomass and seed yields under different climate conditions, applying the AquaCrop model. The data came from experiments conducted under moderate continental climate conditions at Stitar (Serbia) and Mediterranean climate conditions at Cukurova (Turkey). At Stitar, there were three different inter-row spacings (high (S-d), medium (S-m) and low (S-w) crop densities), while at Cukurova there was only high crop density (S-n). In the calibration process, the initial canopy cover, canopy expansion and maximal canopy cover were adapted to each crop density, while the other conservative parameters were adjusted to correspond to all climate conditions. Calibration results showed a very good match between measured and simulated seed yields; the values of the coefficient of determination (0.922). The biomass simulation was very good for Cukurova (R-2=0.97), but somewhat poorer for Stitar (R-2=0.72). Other statistical indicators were high such as Willmott index of agreement of both the calibrated and validated data sets, for both study areas >0.916 and normalized root mean square error in the range from 9-18%. The AquaCrop model was found to be more reliable for Italian ryegrass biomass and seed yield predictions under mild winter climate conditions, with adequate water supply, compared with moderate climate and water shortage conditions.

AB  - The analysis of spatiotemporal changes of temperature extremes in Serbia, based on 18 ETCCDI indices, was performed using daily minimum and maximum temperature observations from 26 meteorological stations over the period 1961-2010. The observation period was divided into two sub-periods (1961-1980 and 1981-2010) according to the results of the sequential Mann-Kendall test. Temporal trends were evaluated by a least-squares linear regression method. The average annual minimum temperature displayed a mixed pattern of increasing, decreasing, and no trends over 1961-1980 and a significant increasing trend over 1981-2010 across the whole country, with a regionally averaged rate of 0.48 degrees C per decade. The average annual maximum temperature showed a decreasing trend during 1961-1980 and a significant increasing trend at all stations during 1981-2010, with a regionally averaged rate of 0.56 degrees C per decade. Hot indices exhibited a general cooling tendency until 1980 and a warming tendency afterwards, with the most pronounced trends in the number of summer and tropical days during the first period and in the frequency of warm days and nights in the second. Cold indices displayed a mostly warming tendency over the entire period, with the most remarkable increase in the lowest annual maximum temperature and the number of ice days during the first period and in the frequency of cool nights during the second. At most stations, the diurnal temperature range showed a decrease until 1980 and no change or a slight increase afterwards. The lengthening of the growing season was much more pronounced in the later period. The computed correlation coefficient between the annual temperature indices and large-scale circulation features revealed that the East Atlantic pattern displayed much stronger association with examined indices than the North Atlantic Oscillation and East Atlantic/West Russia pattern.

AB  - The present research was conducted during the dry and warm growing seasons of 2011, 2012 and 2013 at Guca, which is a well-known potato-growing region of Serbia. Potato was grown under both rainfed conditions and with irrigation, applying two methods: sprinkler and subsurface drip irrigation. The objective of the research was to conduct a comparative analysis and assess the profitability of potato production under rainfed conditions and with irrigation by these two methods. The main outcome of the research showed that higher yields and more profitable production are achievable with irrigation, compared to rainfed conditions. Subsurface drip irrigation was found to be more profitable than sprinkler irrigation. The results provided insight into the structure and distribution of income and expenses, the income and expense growth trend, the percentage profit growth in the case of sprinkler and subsurface drip irrigation, as well as potential income losses at the national level if the irrigation methods considered are not used. A detailed analysis of the production costs provided insight into the feasibility of optimizing potato-growing approaches for all three types of production. The higher profitability of irrigated potato production opens the question of the need to increase irrigation coverage in Serbia.

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.

AB  - Chemical properties of water (pH, electrical conductivity and carbonate, bicarbonate, chloride, calcium, magnesium and sodium concentrations) of the water in the drainage canals of Galovica and Petrac, southeastern Srem, were tested in the period from 2008 to 2010. The objective was to determine the interaction between water quality and hydrological and anthropogenic drivers that characterize these two drainage areas, as well as to find out whether the water complies with quality requirements for irrigation. The results show that hydrological and anthropogenic factors do affect the quality of water in the drainage canals. It is poorer than that of the Sava River, which is the recipient of the drained waters. The concentrations of salts in the canal water, if used for crop irrigation, pose a low-to-moderate risk. Elevated bicarbonate concentrations restrict the application of drip or sprinkler irrigation systems. Irrigation of large surfaces in the drainage areas of Galovica and Petrac would require the Galovica and Petrac pumping stations to be reversible, so that, when needed, they can pump water from the Sava into the system of drainage canals.

AB  - In view of the fact that water is a limited resource, the present research aims to contribute to the development of various approaches and measures that will save water while achieving economically-viable crop yields. The goal of this research was to test the effect of kaolinite on crop quality and water use efficiency (WUE) in the case of peppers irrigated with various treatments. The object of research was the Elephant Ear pepper. A field experiment was conducted, based on a two-factorial, completely random block design with three replications. The first factor was the irrigation treatment mode (full irrigation (F) and two levels of deficit irrigation (R1 and R2)), and the second factor was the application of kaolinite (treatments with and without a 5% kaolinite suspension). All the treatments threated with kaolin has been labelled with a sign K. The research has been conducted at the experimental field of Napredak AD Stara Pazova on Chernozem soil type during three vegetative seasons (May-September) in the years 2011-2013. In the year 2011 the vegetative period of pepper lasted 120 days (from 16 May to 15 September), 113 days (from 18 May to 7 September) in the year 2012 and 117 days in 2013 (from 20 May to 13 September). The years were warm, having intensive dry period during July and August. Precipitation sum during the vegetation of pepper was for around 150 mm lower than the average sum for the 20 year period. A large number of parameters were monitored, including: soil moisture (water content of the soil in all irrigation treatments, with and without the application of kaolinite), canopy cover, dry biomass accumulation, leaf area index, water consumption (evapotranspiration, real evapotranspiration), water stress (leaf temperature, leaf-to-air temperature ratio, plant water stress index), yields (average yield of fresh and dried peppers, fresh and dry biomass, first-class yield, second-class yield, first- and second-class yield), physical properties (number of peppers per plant, pepper mass, pepper length, pepper diameter, sunburn), chemical properties (sugar and organic acid content and total antioxidant activity), and WUE (all peppers, first-class peppers, second-class peppers, and first- and second-class peppers). The highest soil moisture, or the greatest water content of the soil, was noted in the case of full irrigation, with and without kaolinite. The greatest canopy cover and the highest rate of dry biomass accumulation were achieved with full irrigation...
AB  - S obzirom da je voda ograničen resurs, istraživanja idu u smeru pronalaženja različitih sistema i mera kojima se štedi voda, a postižu zadovoljavajući ekonomsko opravdani prinosi. Cilj ovog rada je bio ispitivanje uticaja kaolina na prinos, kvalitet plodova i efikasnost korišćenja vode paprike gajene u različitim režimima navodnjavanja. Istraživanje je obavljeno na paprici sorte Slonovo uvo. Korišćen je metod poljskog ogleda, ogled je postavljen kao dvofaktorijalni po blok sistemu u tri ponavljanja. Prvi ispitivani faktor bio je režim navodnjavanja (puno navodnjavanje (F) i dva nivoa redukovanog navodnjavanja (R1 i R2)), drugi faktor je bio primena kaolina (tretmani sa i bez primene petoprocentne suspenzije kaolina). Svi tretmani sa primenom kaolina imaju oznaku K. Ispitivanja su obavljena na oglednom polju poljoprivrednog dobra „Napredak“ a. d. – Stara Pazova na zemljištu tipa karbonatni černozem tokom tri godine u periodu maj - septembar (2011., 2012., 2013.). Vegetacija paprike u 2011. godini trajala je 120 dana (16. maj – 15. septembar), 113 dana u 2012. (18. maj – 7. septembar) i 117 dana u 2013. godini (20. maj – 13. septembar). Sve tri godine su bile veoma tople, sa veoma izraženim sušnim periodom tokom jula i avgusta. Suma padavina tokom vegetacionog perioda bila je za oko 150 mm niža od proseka. Tokom istraživanja praćen je veliki broj parametara: vlažnost zemljišta (sadržaj vode u zemljištu na svim tretmanima navodnjavanja sa i bez primene kaolina), zasenčenost zemljišta lisnom masom i akumulacija suve biomase, indeks lisne površine, potrošnja vode biljaka (evapotranspiracija kulture, realna evapotranspiracija), pokazatelji vodnog stresa (temperatura lista, temperaturna razlika lišća i vazduha, biljni vodni stres indeks), prinos i parametri prinosa (prosečan prinos sveže i suve mase plodova paprike i sveže i suve biomase, prinos plodova paprike prve klase, prinos plodova druge klase, prinos plodova prve i druge klase), fizičke osobine plodova (broj plodova po biljci, masa ploda, dužina ploda, prečnik ploda, prisustvo ožegotina od sunca), hemijske osobine plodova (sadržaj šećera, organskih kiselina i ukupna antioksidativna aktivnost) i efikasnost korišćenja vode (efikasnost korišćenja vode pri proizvodnji svih plodova paprike, pri proizvodnji plodova prve klase, pri proizvodnji plodova druge klase i efikasnost korišćenja vode pri proizvodnji plodova paprike prve i druge klase)...

Cilj ovog rada je bio ispitivanje uticaja kaolina na prinos, kvalitet plodova i efikasnost korišćenja vode paprike gajene u različitim režimima navodnjavanja. Istraživanje je obavljeno na paprici sorte Slonovo uvo. Korišćen je metod poljskog ogleda, ogled je postavljen kao dvofaktorijalni po blok sistemu u tri ponavljanja. Prvi ispitivani faktor bio je režim navodnjavanja (puno navodnjavanje (F) i dva nivoa redukovanog navodnjavanja (R1 i R2)), drugi faktor je bio primena kaolina (tretmani sa i bez primene petoprocentne suspenzije kaolina). Svi tretmani sa primenom kaolina imaju oznaku K. Ispitivanja su obavljena na oglednom polju poljoprivrednog dobra „Napredak“ a. d. – Stara Pazova na zemljištu tipa karbonatni černozem tokom tri godine u periodu maj - septembar (2011., 2012., 2013.). Vegetacija paprike u 2011. godini trajala je 120 dana (16. maj – 15. septembar), 113 dana u 2012. (18. maj – 7. septembar) i 117 dana u 2013. godini (20. maj – 13. septembar). Sve tri godine su bile veoma tople, sa veoma izraženim sušnim periodom tokom jula i avgusta. Suma padavina tokom vegetacionog perioda bila je za oko 150 mm niža od proseka. Tokom istraživanja praćen je veliki broj parametara: vlažnost zemljišta (sadržaj vode u zemljištu na svim tretmanima navodnjavanja sa i bez primene kaolina), zasenčenost zemljišta lisnom masom i akumulacija suve biomase, indeks lisne površine, potrošnja vode biljaka (evapotranspiracija kulture, realna evapotranspiracija), pokazatelji vodnog stresa (temperatura lista, temperaturna razlika lišća i vazduha, biljni vodni stres indeks), prinos i parametri prinosa (prosečan prinos sveže i suve mase plodova paprike i sveže i suve biomase, prinos plodova paprike prve klase, prinos plodova druge klase, prinos plodova prve i druge klase), fizičke osobine plodova (broj plodova po biljci, masa ploda, dužina ploda, prečnik ploda, prisustvo ožegotina od sunca), hemijske osobine plodova (sadržaj šećera, organskih kiselina i ukupna antioksidativna aktivnost) i efikasnost korišćenja vode (efikasnost korišćenja vode pri proizvodnji svih plodova paprike, pri proizvodnji plodova prve klase, pri proizvodnji plodova druge klase i efikasnost korišćenja vode pri proizvodnji plodova paprike prve i druge klase)...",

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.

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  - Maize is the most important agricultural product in Serbia, providing the largest revenue stream. Maize production in Serbia is largely rainfed and dependent on weather conditions. In the past four decades, the area of Zemun (Vojvodina Province) registered an upward air temperature trend, a decrease in summer rainfall, and a downward maize grain yield trend. Since Serbia is faced with climate change and increasing drought, the aim of the paper is to examine the agronomic and economic impacts of shifting maize production from rainfed to irrigated. An experimental study was carried out in the most important agricultural region of Serbia (Vojvodina), where maize was grown in both rainfed and irrigated conditions (2002-2010). Maize grain yields and climate parameters were recorded. The results showed that each year during the growing season, the crops were exposed to some degree of water deficit. The average water deficit in June, July and August was 48 mm, 98 mm and 88 mm, respectively. During that period maize underwent phenological stages in which its sensitivity to drought was high. Rainfed maize grain yields varied considerably from year to year, ranging from 8.57 t ha(-1) to 12.73 t ha(-1) (average 10.46 t ha(-1)). Irrigation increased yields by 4.8-48% (average 18.7%). This increase depended on weather conditions; the highest increase was noted in a dry and very warm season. The economic assessment confirmed higher profitability of irrigated maize (841.79(sic)/ha vs. rainfed 699.35(sic)/ha). Irrigation increased overall costs by 10.75% and profits by 21.4% (142.44(sic)/ha), compared to rainfed conditions. The estimated average annual loss incurred in Serbia due to a lack of irrigation in maize production is 122,161,287(sic). Considering the results of this research, as well as predictions of increasing drought in South East Europe, irrigation appears to be essential for successful maize production in Serbia and the entire region.

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  - In suburban Belgrade, there are some 200 local water supply systems which are not connected to either the Belgrade Water Supply System or to supply systems operated by municipal utilities. The small systems in Belgrade suburbs are either operated by local municipality (local government) or even by the group of local citizens who have neither technical capability nor financial resources to do it properly. Roughly 200,000 of Belgrade's inhabitants obtain their drinking water from these water supply systems. The water quality delivered by these local water supply systems is often compromised in terms of microbiological, physical and/or chemical compliance with drinking water standards in addition to the general lack of strategy on water safety plans and risk assessment. WHO Guidelines on water quality standards as well as the recommendations on safety plans and whole risk assessment are strictly respected in the main (central) Water Supply System in Belgrade. Most frequently, elevated concentrations of ammonia, nitrites, nitrates and iron lead to lack of chemical compliance, while elevated counts of aerobic mesophilic bacteria and the presence of bacteria indicative of faecal pollution tend to be behind microbiological lack of compliance with drinking water standards. In most cases, failure to meet drinking water standards can be attributed to groundwater pollution. No sewer system exists in these areas, and wastewater from septic tanks, in practice infiltration wells, is in direct contact with groundwater. Of a total of 72 laboratory-tested drinking water samples, 51.3% failed to meet physical and/or chemical standards, and 73.6% failed to meet microbiological standards. Groundwater pollution can only be prevented if wastewater disposal system is provided for all households and all suburban residential areas which obtain their water supply from local water supply systems. Some possible mitigation measures have been indicated. In the interim period, water must be disinfected continually, and the feasibility of ozonation or UV irradiation, in addition to chlorination, should be assessed.
