AB  - Physical properties play an important role in determining suitability of soil for agricultural, amelioration, ecological and technical purposes. They are influence on movement, storage and availability of water and nutrients for plants, ease of plant root penetration and movement of heat and air. Furthermore, they are also effect chemical and biological properties of soil. Although Fluvisols (alluvial-meadow soils) are one of the most widespread soils in Serbia, little research has been done on them. The aim of this study was therefore to evaluate the most important physical properties of long-term irrigated Fluvisols that were formed on the carbonate deposit of the White Drim River in Kosovo and Metohija (Serbia). Eight profiles, i.e. 23 undisturbed soil samples and 69 disturbed soil samples were examined. The depth of the upper part of the soil profile, which lies above the layer of sand, stones and gravel, in which the roots of the plants develop, is very uneven from profile to profile, i.e. it varies from small (approx. 30 cm) to very large (>200 cm). The investigated Fluvisols are heavy textured (>50% clay content). The results show a high variability of the physical properties in the surface layer of these soils. Most of the investigated physical properties of the eight open Fluvisol profiles, in addition to the heavy texture, are quite favorable and fairly uniform in the plow layer, while they are much less favorable, though not particularly unfavorable, under the plow layer in deeper profiles.

AB  - The effects of long-term (>20 yr) grazing on the selected physical properties of a non carbonated silty-clay Fluvisols were studied in the region of the Kolubara Valley, Northwest Serbia. Two adjacent land-use types (native deciduous forest and natural pasture soils converted from forests for more than 20 years) were chosen for the study. Disturbed and undisturbed soil samples were collected from three sites at each of the two different land-use types from the depths of 0–15, 15–30 and 30–45 cm. In relation to the soil under native forest, soil organic matter content, total porosity and air-filled porosity were significantly reduced after long-term of grazing. The bulk density (0.99–1.48 g cm–3) and the saturated hydraulic conductivity (6.9.10–2–3.2.10–4 cm s–1) were significantly lower in forest compared to the adjacent pasture (ex-forest) soil (1.49–1.55 g cm–3 and 3.4.10–4–5.5.10–4 cm s–1, respectively). In addition, forest had significantly lower dry mean weight diameter (7.0–9.2 mm) and greater wet mean weight diameter (2.0–2.6 mm) for 0–45 cm depth compared with the pasture (8.8–9.4 mm and 1.8–2.3 mm, respectively). The decrease of soil organic matter content and reduction in aggregate stability under long-term grazing rendered the soil more susceptible to compaction. In conclusion, the results of this study indicate that removal of permanent vegetation in the conversion process from forest areas to pasture land may lead to loss of soil productivity and serious soil degradation. Obviously, there is a need for greater attention to developing sustainable land use practices in management of these ecosystems to prevent further degradation of pasture soils in the region.

AB  - The goal of this research is to determine the effects of different levels of water deficit (I100: full irrigation, I65: 35% deficit, I40: 60% deficit and I0: no irrigation) on yield and chemical composition of soybean [Glycine max (L.) Merr.] grown in Srem region of Serbia. Water deficit significantly affected the yield and chemical composition of soybean seeds. The lowest (1.63 t/ha) and the highest (3.21 t/ha) seed yields were obtained from I0 and I65 treatments, respectively. Furthermore, the highest protein (1092 kg/ha) and oil (563 kg/ha) yields were observed in I65 treatment. Lower and higher irrigation levels from I65 decreased the protein and oil yields. Our data indicated that irrigation generally increased K, P, Mg, Mn, Cu, Zn and B concentrations and decreased Ca and Fe concentrations in soybean seed. It was clearly observed that full-watered treatment (I100) provided no potential benefit in terms of soybean yield and chemical composition. For higher economic yield and good nutritional quality, water-saving treatment I65 could be suitable in soybean management in Srem region of Serbia as in other regions with similar soil and climate conditions.

AB  - This study examines the effects of different irrigation regimes on seed yield and yield components of sprinkler-irrigated soya bean [(Glycine max (L.) Merr.] under field conditions in 2006, 2007 and 2008 in Zemun Polje (Srem, Srbija). Four irrigation regimes: 80-85% (T1), 70-75% (T2), 60-65% (T3) of field capacity, and non-irrigated regime (T0) were evaluated each experimental year. The experimental design was a randomised complete block with four replications on a Calcaric Chernozem. Water stress (drought) during growing season in the non-irrigated treatment (T0) decreased plant physiological activity, vegetative growth, and productivity of soya bean. Irrigation treatments significantly (P  lt  0.01) influenced soya bean seed yield and yield components. The treatment T2 produced higher seed yield than T1 and T3. Irrigation regimes had statistically significant different effects on yield components such as the plant height at harvest, number of pods per plant, number of seeds per plant, mass of pod with seeds per plant, 1,000 seed mass and hectoliter mass of soya bean seeds. Yield reduction was mainly due to a lower number of pods and seeds per plant and lower seed mass. The T1 treatment had the highest plant height of soya bean in all three growing years. The results have shown that under water scarcity, the treatment T3 is an acceptable irrigation strategy to stabilize and increase soya bean yield in Srem and neighboring countries in the region, provided that this practice is not prevented by economic constraints.
AB  - U ovom radu ispituje se uticaj različitih režima navodnjavanja orošavanjem na prinos i komponente prinosa semena soje [(Glycine max (L.) Merr.] u poljskim uslovima u 2006, 2007. i 2008. godini u Zemun Polju (Srem, Srbija). Svake godine istraživana su po tri režima navodnjavanja, i to sa 80-85% (T1), 70-75% (T2), 60-65% (T3) poljskog vodnog kapaciteta i prirodni vodni režim bez navodnjavnja (T0). Ogled je izveden po metodi slučajnog blok sistema u četiri ponavljanja na karbonatnom černozemu. Deficit vode u toku vegetacionog perioda u nenavodnjavanom tretmanu (T0) smanjio je fiziološku aktivnost biljaka, vegetativni rast i produktivnost soje. Navodnjavani tretmani su vrlo značajno (P  lt  0,01) uticali na prinos zrna soje i komponente prinosa. Na tretmanu T2 postignut je veći prinos semena nego na tretmanima T1 i T3. Iako je tretman T2 dobio oko 37% manje vode za navodnjavanje u poređenju sa T1, prinos soje povećan je u proseku za 11%. Navodnjavani režimi imali su statistički značajno različite uticaje na komponente prinosa kao što su visina biljaka u vreme žetve, broj mahuna i zrna po biljci, masa mahuna po biljci, masa zrna po biljci, masa 1.000 zrna i zapreminska masa zrna. Smanjenje prinosa je uglavnom posledica manjeg broja mahuna i zrna po biljci i manje mase 1.000 zrna. Tretman T1 imao je najveću visinu biljaka u sve tri godine ispitivanja. Rezultati su pokazali da je tretman T3 prihvatljiva strategija navodnjavanja za stabilizaciju i povećanje prinosa soje u Sremu i susednim zemljama regiona u uslovima ograničenih vodnih resursa, pod uslovom da ova praksa nije sprečena ekonomskim ograničenjima.

Four irrigation regimes: 80-85% (T1), 70-75% (T2), 60-65% (T3) of field capacity, and non-irrigated regime (T0) were evaluated each experimental year. The experimental design was a randomised complete block with four replications on a Calcaric Chernozem. Water stress (drought) during growing season in the non-irrigated treatment (T0) decreased plant physiological activity, vegetative growth, and productivity of soya bean. Irrigation treatments significantly (P  lt  0.01) influenced soya bean seed yield and yield components. The treatment T2 produced higher seed yield than T1 and T3. Irrigation regimes had statistically significant different effects on yield components such as the plant height at harvest, number of pods per plant, number of seeds per plant, mass of pod with seeds per plant, 1,000 seed mass and hectoliter mass of soya bean seeds. Yield reduction was mainly due to a lower number of pods and seeds per plant and lower seed mass. The T1 treatment had the highest plant height of soya bean in all three growing years. The results have shown that under water scarcity, the treatment T3 is an acceptable irrigation strategy to stabilize and increase soya bean yield in Srem and neighboring countries in the region, provided that this practice is not prevented by economic constraints., U ovom radu ispituje se uticaj različitih režima navodnjavanja orošavanjem na prinos i komponente prinosa semena soje [(Glycine max (L.) Merr.] u poljskim uslovima u 2006, 2007. i 2008. godini u Zemun Polju (Srem, Srbija). Svake godine istraživana su po tri režima navodnjavanja, i to sa 80-85% (T1), 70-75% (T2), 60-65% (T3) poljskog vodnog kapaciteta i prirodni vodni režim bez navodnjavnja (T0). Ogled je izveden po metodi slučajnog blok sistema u četiri ponavljanja na karbonatnom černozemu. Deficit vode u toku vegetacionog perioda u nenavodnjavanom tretmanu (T0) smanjio je fiziološku aktivnost biljaka, vegetativni rast i produktivnost soje. Navodnjavani tretmani su vrlo značajno (P  lt  0,01) uticali na prinos zrna soje i komponente prinosa. Na tretmanu T2 postignut je veći prinos semena nego na tretmanima T1 i T3. Iako je tretman T2 dobio oko 37% manje vode za navodnjavanje u poređenju sa T1, prinos soje povećan je u proseku za 11%. Navodnjavani režimi imali su statistički značajno različite uticaje na komponente prinosa kao što su visina biljaka u vreme žetve, broj mahuna i zrna po biljci, masa mahuna po biljci, masa zrna po biljci, masa 1.000 zrna i zapreminska masa zrna. Smanjenje prinosa je uglavnom posledica manjeg broja mahuna i zrna po biljci i manje mase 1.000 zrna. Tretman T1 imao je najveću visinu biljaka u sve tri godine ispitivanja. Rezultati su pokazali da je tretman T3 prihvatljiva strategija navodnjavanja za stabilizaciju i povećanje prinosa soje u Sremu i susednim zemljama regiona u uslovima ograničenih vodnih resursa, pod uslovom da ova praksa nije sprečena ekonomskim ograničenjima.",

AB  - In the Vojvodina region, drought is an important factor limiting grain yield in maize. The aims of this research were to compare irrigation scheduling in maize (cv. ZP SC 684), and to evaluate grain yield and ear characteristics. A 3-year field experiment was carried out in the Vojvodina region, a northern part of the Republic of Serbia (384 mm of rainfall in the maize-growing period). Maize was subjected to four irrigation levels (rainfed - I0 and supply at 80-85% - I1, 70-75% - I2 and 60-65% - I3 of field capacity). The results indicated a large yearly variability, mainly due to a rainfall event at the flowering, fertilization and grain filling stages. A significant irrigation effect was observed for all the variables under study, with significant differences between the three irrigation treatments. The grain yield ranged between 8.73 and 16.33 t ha-1. The highest grain yield of maize (average of 15.08 t ha-1) was in the I1 treatment, while the non-irrigated (I0) treatment had the lowest yield (average of 10.20 t ha-1), a 35% grain yield reduction. With the decrease of irrigation water, the grain yield of maize decreased. The most distinctive impact the irrigation had on maize yield was during the warm and very dry growth period of the year of 2008. Maize in the Vojvodina region can be cultivated with acceptable yields while saving irrigation water and maximizing resource-use efficiency.
AB  - U Vojvodini, suša je važan faktor koji ograničava prinos kukuruza. Ciljevi ovog istraživanja bili su upoređivanje prirodnog i različitih irigacionih vodnih režima u kukuruzu (cv. ZP SC 684 - FAO 600), ocena prinosa i osobina klipa. Trogodišnja eksperimentalna istraživanja obavljena su u Zemun Polju (Vojvodini), odnosno u severnom delu Republike Srbije (dvadesetogodišnji prosek padavina u vegetacionom periodu kukuruza je 384 mm). Ispitivan je efekat četiri varijante vodnog režima kukuruza: I0 - bez navodnjavanja, I1 - sadržaj vode u zemljištu održavan je na nivou 80-85% poljskog vodnog kapaciteta (PVK) dopunskim navodnjavanjem kišenjem, I2 - 70-75% PVK i I3 - 60-65% PVK. Rezultati su pokazali veliku varijabilnost između godina, uglavnom zbog pojave padavina u fenofazi cvetanja, oplodnje i nalivanja zrna. Navodnjavanje je značajno uticalo na prinos zrna, karakteristike klipa i visinu biljaka kukuruza. Takođe, utvrđene su značajne razlike i između navodnjavanih varijanti. Prinos zrna varirao je između 8,73 i 16,33 t ha-1. Najveći prinos kukuruza (prosečno 15,08 t ha-1) ostvaren je u varijanti I1, a najmanji (10,20 t ha-1) u nenavodnjavanoj (I0) varijanti. Prinos se smanjivao i do 35% sa smanjenjem količine vode za navodnjavanje. Najizraženiji efekat dopunskog navodnjavanja na prinos zrna kukuruza ostvaren je u toplom i veoma sušnom vegetacionom periodu 2008. godine. Kukuruz u Vojvodini može da se gaji sa prihvatljivim prinosima uz uštedu vode za navodnjavanje, što će rezultirati efikasnijim korišćenjem vodnih resursa.

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  - The study of effects of water stress on yield and water use by onion plants was carried out at the experimental field of the Institute of Field and Vegetable Crops in Novi Sad in the period 2005-2007. Onion sensitivity to water stress was determined using a yield response factor (Ky). The values of Ky were derived from the linear relationship between relative evapotranspiration deficits (1-ETa/ETm) and relative yield decrease (1-Ya/Ym). To assess the irrigation effect on onion yield, irrigation water use efficiency (Iwue) and evapotranspiration water use efficiency (ETwue) were determined. Values of Ky in the growing season (Ky 1.78) indicate that onion is highly sensitive to water stress under the climate conditions of the Vojvodina region. The amounts of water used on evapotranspiration under irrigation and non-irrigation conditions ranged from 448.4 to511.9 mm, and 290.2 to 393.9 mm, respectively. The values of Iwue and ETwue varied from 4.35 to 28.05 kg ha-1/m-3 and 7.87 to 19.51 kg ha-1/m-3, respectively, mostly depending on the favorableness of the year for the onion production and irrigation water applied. Ky, Iwue and ETwue can be used as a good basis for onion growers in the region in terms of optimum irrigation water use, for the planning, design and operation of irrigation projects in the region, and also for the improvement the production technology of the crop.

The amounts of water used on evapotranspiration under irrigation and non-irrigation conditions ranged from 448.4 to511.9 mm, and 290.2 to 393.9 mm, respectively. The values of Iwue and ETwue varied from 4.35 to 28.05 kg ha-1/m-3 and 7.87 to 19.51 kg ha-1/m-3, respectively, mostly depending on the favorableness of the year for the onion production and irrigation water applied. Ky, Iwue and ETwue can be used as a good basis for onion growers in the region in terms of optimum irrigation water use, for the planning, design and operation of irrigation projects in the region, and also for the improvement the production technology of the crop.",

AB  - The aim of the present study was to observe the response of maize hybrids under rainfed and irrigation conditions of the soil in order to establish the dependence of yielding potential on the water amounts reaching the soil surface during the growing season. The four-replicate trail was set up according to the randomised complete-block design on chernozem. Pre-watering soil moisture was approximately 70% of field water capacity, and soil moisture was established thermogravimetrically. During the five-year studies, the following differences in yields could be as follows: 12.68 t ha-1 (ZP 341); 12.76 t ha-1 (ZP 434); 13.17 t ha-1 (ZP 578); 14.03 t ha-1 (ZP 684) and 13.75 t ha-1 (ZP 704) under conditions of 440 mm, 440 mm, 424 mm, 457 mm and 466 mm of water, respectively. The hybrid ZP 341, i.e. ZP 578 expressed the highest, i.e. the lowest tolerance in dry relative seasons, respectively. The reduction of the water amount for every 10 mm decreased the yield by 119.4 kg ha-1 (ZP 341), 156.7 kg ha-1 (ZP 434), 172.3 kg ha-1 (ZP 578), 148.9 kg ha-1 (ZP 684) and 151.1 kg ha-1 (ZP 704).

AB  - The aim of this study was to investigate the effects of land use changes on the aggregate size distribution, soil structural stability, and soil erodibility in Luvisols on Central Serbia's rainfed farms at a depth of 0.00-0.30 m. Six sites, selected for the study, contained adjacent land uses of natural grassland and arable land that have undergone conversion from grassland for more than 10 years. The inherent problems of Luvisols include weak structured surface horizons susceptible to structure deterioration, where tilled when wet or when heavy machinery is used. Aggregate size distribution and soil structural stability in the topsoil was tested by soil dry and wet sieving. Soil erodibility was assessed with the USLE-K factor. The natural grassland served as a control against which to assess changes in soil properties resulting from the removal of natural vegetation or cultivation of soil. The results showed that conversion of natural grassland to dry land farming led to a significant degradation of the soil structure. Aggregate separation by dry-sieving indicated that the natural grassland had significantly fewer unfavorable cloddy aggregates (>10 mm) and more agronomically most valuable aggregates (0.25-10 mm) than the arable soils. The mean weight diameter of dry aggregates (MWDdry) was greater in the grassland (7.0 mm) compared to the arable soils (9.7 mm). The arable soil had significantly lower (1.03) structure coefficient (Ks) than grassland soils (2.77). Higher percentages of water stable aggregates (WSA) >0.25 mm were found under natural grassland (50 %) than in arable fields (41 %). In addition, grassland soil had significantly higher mean weight diameter (0.92 mm) of wet stable aggregates (MWDwet) than arable soils (0.81 mm). Tillage of the unaltered grassland significantly increased the soil erodibility measured by the USLE-K factor. The USLE-K factor was approximately by 17% greater in the arable soil than in the grassland, indicating the vulnerability of the arable soil to water erosion. In summary, the results showed that the tillage of the grassland degraded the soil structure, leaving soils more susceptible to the erosion in the temperate climate zone. This suggests that land disturbances should be avoided in the grasslands in the study region of the Central Serbia.

AB  - The study of effects ofwater stress on yield and water use by maize plants was carried out in the experimental field of the Maize Research Institute at Zemun Polje in the period 2006-2008. Maize sensitivity to water stress was determined using a yield response factor (Ky). The values of Ky were derived from the linear relationship between relative evapotranspiration deficits (1-ETa/ETm) and relative yield decrease (1-Ya/Ym). To assess the irrigation effect on maize yield, irrigation water use efficiency (Iwue) and evapotranspiration water use efficiency (ETwue) were determined. Values of Ky in the growing season (Ky 0.94) indicate that maize is moderately sensitive to water stress under the climate conditions of Serbia. The amounts of water used on evapotranspiration under irrigation (ETm) and non-irrigation (ETa) conditions ranged from 453 to 501 mm, and 257 to 363 mm, respectively. The values of Iwue and ETwue varied from 0.020 to 0.0361 ha-1/mm and 0.024 to 0.0381 ha-1/ mm, respectively, mostly depending on the favourableness of the year for the maize production and irrigation water applied. Ky, Iwue and ETwue can be used as a good basis for maize growers in the region in terms of optimum irrigation water use, for the planning, design and operation of irrigation projects in the region, and also for the improvement the production technology of the crop.

Osetljivost kukuruza na vodni stres u periodu vegetacije utvrđena je na osnovu vrednosti koeficijenta opadanja prinosa - Ky. Vrednosti Ky su obračunate iz odnosa relativnog opadanja prinosa (1-Ya/Ym) i relativnog deficita evapotranspiracije (1-ETa/ETm).

Vrednosti Ky u vegetacionom periodu (Ky 0,94) ukazuju da je kukuruz umereno osetljiv na vodni stres u klimatskim uslovima Srbije.

AB  - Extensive organic production under irrigation conditions requires greater amounts of NPK fertilisers. Furthermore, the mobility of fertilisers, especially of nitrogen, is greater under the increased soil moisture content, hence the incorporation of unnecessary amounts leads to nitrogen leaching into deeper layers causing pollution of the agro ecosystem. The objective of the present study was to determine maize yields and the content of NPK in soil under irrigation conditions after three years of the application of the same fertiliser amounts. There were four variants of water regime in the trail and the following amounts of fertilisers were incorporated: 136 kg N ha-1, 68 kg P2O5 ha-1 and 68 kg K2O ha-1. The obtained results show that the greatest differences in the content of the available soil nitrogen were established in relation to the rainfed regime. Moreover, under rainfed conditions, the highest nitrogen content (9.84 mg kg-1) and the lowest yield (10.2 t ha-1) were recorded at the end of the performed experiment. The lowest nitrogen content in the soil (7.84 mg kg-1) was established in the variant in which soil moisture had been maintained at the level 70-75% of filed water capacity (FWC). At the same time the average yield in this variant amounted to 13.55 t ha-1. The higher moisture was (80-85% FWC) the higher maize yield was (15.08 t ha-1), but also the nitrogen mobility over a profile depth was, and a greater holding capacity of nitrite in the humus horizon was. In comparison with rainfed conditions, irrigation variants had lower contents of P2O5 and K2O in the soil, which is, among other things, a consequence of higher yields obtained under irrigation conditions. .

U uslovima prisustva veće količine vode (80-85% PVK) bila je najveća rodnost kukuruza (15,08 t·ha-1), ali i veća pokretljivost azota po dubini profila, kao i zadržavanje nitrata u humusnom horizontu. U poređenju sa prirodnim vodnim režimom, varijante sa navodnjavanjem su imale manji sadržaj P2O5 i K2O u zemljištu što je, između ostalog, zbog ostvarenih većih prinosa u navodnjavanju. .

AB  - The aim of this study was to use results of experimental work to analyse effects of maize irrigation and to quantify basic parameters that are included into exploitation costs of a long-ranged self-propelled sprayer, so called typhoon sprinkler. The four-replicate trial was carried out according to a randomised block design in the experimental fields of the Maize Research Institute, Zemun Polje, during the 2002-2008 period. The irrigation was applied in all years but 2004 in which the precipitation sum was sufficient to maintain soil moisture above the predetermined pre-watering soil moisture. According to obtained results, effects of irrigation on grain yields over years varied from to 0.315 t ha-1 to 4.459 t ha-1. Furthermore, the input to output ratio varied over years. The long-term average shows that each tone of a yield obtained by irrigation was loaded by consumed energy of 328 kWh used for the operation of a submersible pump that supplied the typhoon sprinkler with a necessary water amount (555 m3) from a deep well, then with approximately 2 l of fuel necessary for the tractor operation and with 17 hours of labour. .

AB  - In order to investigate the possibility of onion production from seed in conditions without irrigation under the ecological conditions of Vojvodina the study was conducted at Rimski Šančevi experiment field of Institute of Field and Vegetable Crops on the calcareous chernozem soil of the loess terrace. Potential evapotranspiration (ETP) of onion during growing season were calculated using the procedure of water balance, and bioclimatic method using hydrophytothermic index (K), the value of which had been estimated at 0.19 for onion in the climate of Vojvodina. After determining the ETP value, the actual evapotranspiration (ETR) was calculated on the basis of precipitation data and pre-vegetation soil water reserve. These values were then used to calculate the readily available soil water deficit during the onion growing season. In the study period the consumption of water on the ETP and ETR ranged from 446-495 mm and 249-417 mm respectively. Deficit of readily available water in the soil was 78 mm, 114 mm and 197 mm in 2005, 2006 and 2007 respectively. Determined deficit of readily available water in the soil was negatively affect all tested parameters (bulb yield r = -0.847**, bulb weight r = - 0.760**, bulb diameter r = - 0.712**, bulb height r = - 0.547*, plant height r = -0.864**). Based on the results, it can be concluded that the production of onions from seed in varying climatic conditions of Vojvodina is possible only under irrigation conditions.
AB  - U cilju ispitivanja mogućnosti proizvodnje crnog luka iz semena u uslovima prirodne obezbeđenosti biljaka vodom u agroekološkim uslovima Vojvodine istraživanja su obavljena na Oglednom polju Instituta za ratarstvo i povrtarstvo na Rimskim Šančevima na zemljištu tipa karbonatni černozem lesne terase. Utrošak vode na potencijalnu evapotranspiraciju (ETP) u pojedinim mesecima i vegetacionom periodu, obračunat je bioklimatskim postupkom, primenom hidrofitotermičkog indeksa 0,19. Nakon obračuna ETP bilansiran je utrošak vode na stvarnu evapotranspiraciju (ETR) od padavina i rezervi vode akumuliranih u zemljištu u predvegetacionom periodu i tako utvrđen deficit lakopristupačne vode u periodu vegetacije crnog luka. U ispitivanom periodu utrošak vode na ETP se kretao u intervalu od 446-495 mm, a na ETR 249-417 mm. Deficit lakopristupačne vode u zemljištu bio je 78 mm u 2005, 114 mm u 2006 i 197 mm u 2007 godini. Utvrđeni deficit lakopristupačne vode u zemljištu je negativno uticao na sve ispitivane parametre (prinos lukovica r = -0,847**, masa lukovica r = - 0,760**, prečnik lukovica r = - 0,712**, visina lukovica r = -0,547*, visina biljaka r = - 0,864**). Na osnovu rezultata istraživanja može se zaključiti da je proizvodnja crnog luka iz semena u promenljivim klimatskim uslovima Vojvodine moguća samo u uslovima navodnjavanja.

AB  - A field study was carried out from 2001 to 2007 in order to determine the water-yield relationship of maize in the Vojvodina region, a northern part of the Serbia Republic. The yield response factor (K-y) was calculated to express the response of maize to water stress both for the growing season and specific growth stages. To assess the effectiveness of irrigation on maize yield, an irrigation water use efficiency (I-WUE) and evapotranspiration water use efficiency (ETWUE) were determined. The study indicated that in the climatic conditions of Vojvodina maize is most sensitive to water stress in the flowering and pollination stage (K-y = 0.52), but less sensitive in the stages of vegetative gowth (K-y = 0.37), grain filling and maturity (K-y = 0.41). Values of yield response factor in the growing period (K-y = 0.54) indicated that maize is moderately sensitive to soil water stress in the temperate climatic conditions of Vojvodina. The I-WUE and ETWUE were in intervals of 0.47 to 3.00 kg m(-3) and 0.67 to 2.34 kg m(-3) respectively, mostly depending on the extent of favorable conditions of the season for maize production and irrigation water applied. The parameters K-y, I-WUE and ETWUE could be used by maize growers as a guide in the study region in terms of optimum utilization of irrigation water for the planning, design and operation of irrigation projects and for improving the production technology of the crop.

The I-WUE and ETWUE were in intervals of 0.47 to 3.00 kg m(-3) and 0.67 to 2.34 kg m(-3) respectively, mostly depending on the extent of favorable conditions of the season for maize production and irrigation water applied. The parameters K-y, I-WUE and ETWUE could be used by maize growers as a guide in the study region in terms of optimum utilization of irrigation water for the planning, design and operation of irrigation projects and for improving the production technology of the crop.",

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  - Field pea (Pisum sativum L.) has the potential to be a suitable companion crop for the establishment of red clover (Trifolium pratense L.), as it is fast growing and is harvested early, and thus reduces the duration of competition and allows light to be transmitted through its canopy to an undersown species more so than other companion crops such as small grains. The aim of this study was to determine the suitability of field pea as a companion crop for red clover, and in particular to determine the effect of pea cultivar and plant population density. The field experiment comprised 2 sowing years, (2004 and 2005), and the first cut in the first full harvest year in 2005 and 2006. The factorial component of the experiment involved 2 pea varieties (Jezero: semi-leafless; Javor: normal leaves with reduced leaflet size) and 3 densities (30, 60, and 90 plants m(-2)). Two control treatments were also included in the experiment, i.e. red clover grown as pure stand (control I) and red clover with oat as a cover crop (control II). When the field pea had reached the harvestable stage all plots were cut, followed by 2 additional cuts in the sowing year. Yields at the first cut in the following year were also recorded. Forage and protein yields, as well as the weed proportion were measured. On average, control II produced the highest forage yield, followed by pea as the cover crop; the lowest yield was obtained in the pure stand of red clover. Field pea cultivar yields did not differ significantly. The highest average yield was obtained with 90 plants m(-2). The first cut comprised the highest proportion of annual yield (50%-69% when field pea was included). Red clover establishment was not adversely affected by competition from peas. As crude protein content did not vary much, crude protein yield followed the same trend as forage yield (r = 0.83).

AB  - An experiment was conducted at Rimski Šančevi Experiment Field of Institute of Field and Vegetable Crops in Novi Sad during 2000 - 2005. The soil in the experimental plot was calcareous chernozem on loess terrace. Using the yield response factor (ky), the study investigated how sunflower yield and evapotranspiration were affected by deficit of available soil water during the growing season. The experiment consisted of an irrigated treatment (T1), in which irrigation was used when soil moisture levels dropped to 60-65% of FC (field capacity), and a nonirrigated control treatment (T0). The sunflower hybrid used in the study was NS-H-111. On average, no significant differences in yield level were observed between T1 (3.79 t ha-1) and T0 (3.75 t ha-1) treatments. Seasonal evapotranspiration (ETm) obtained in T1 treatment was in the 402-479 mm range. The yield response factor (ky) was obtained as 0.20 for total growing season and 0.27, 0.31 and 0.48 for vegetative, flowering and yield formation period, respectively. Period from flowering to maturity was the most sensitive towards water deficiency.

AB  - An investigation was carried out at Rimski Šančevi experiment field of Institute of Field and Vegetable Crops in Novi Sad in the period 1997-2007, aiming to determine the sensitivity of maize to soil water deficit at specific growth stages. The values of yield response factor (ky) were derived from the linear relationship between relative seasonal evapotranspiration deficit (1-ETa/ETm) and relative yield loss (1-Ya/Ym). The obtained results indicate that in the climatic conditions of Vojvodina maize is the most sensitive to water stress in the stage of flowering and fertilization (ky 0.49), but less sensitive by the beginning and at the and of growing season in the stage of vegetative growth (ky 0.46) and grain filling and maturity (ky 0.43). Values of yield response factor in the growing period (ky 0.65) indicate that maize is moderate sensitive to soil water stress in the climatic conditions of Vojvodina.
AB  - Eksperimentalna istraživanja uticaja deficita lakopristupačne vode u zemljištu u određenim podperiodima vegetacije kukuruza su obavljena na oglednom polju Naučnog instituta za ratarstvo i povrtarstvo iz Novog Sada, na Rimskim Šančevima u periodu od 1997-2007. godine. Vrednosti koeficijenta opadanja prinosa (ky) su obračunate iz odnosa relativnog opadanja prinosa (1-Ya/Ym) i relativnog deficita evapotranspiracije (1-ETa/ETm). Rezultati istraživanja ukazuju da je kukuruz u klimatskim uslovima Vojvodine najosetljiviji na deficit vode u zemljištu u periodu cvetanje oplodnja (ky 0,49), a manje na početku i kraju vegatacije, u periodu vegetativnog porasta (ky 0,46) i periodu nalivanja zrna i sazrevanja (ky 0,43). Vrednosti koeficijenta opadanja prinosa u periodu vegetacije (ky 0,65) ukazuju da je kukuruz umereno osetljiv na deficit vode u zemljištu u klimatskim uslovima Vojvodine.

abstract = "An investigation was carried out at Rimski Šančevi experiment field of Institute of Field and Vegetable Crops in Novi Sad in the period 1997-2007, aiming to determine the sensitivity of maize to soil water deficit at specific growth stages. The values of yield response factor (ky) were derived from the linear relationship between relative seasonal evapotranspiration deficit (1-ETa/ETm) and relative yield loss (1-Ya/Ym). The obtained results indicate that in the climatic conditions of Vojvodina maize is the most sensitive to water stress in the stage of flowering and fertilization (ky 0.49), but less sensitive by the beginning and at the and of growing season in the stage of vegetative growth (ky 0.46) and grain filling and maturity (ky 0.43). Values of yield response factor in the growing period (ky 0.65) indicate that maize is moderate sensitive to soil water stress in the climatic conditions of Vojvodina., Eksperimentalna istraživanja uticaja deficita lakopristupačne vode u zemljištu u određenim podperiodima vegetacije kukuruza su obavljena na oglednom polju Naučnog instituta za ratarstvo i povrtarstvo iz Novog Sada, na Rimskim Šančevima u periodu od 1997-2007. godine.

AB  - The paper emphasizes the importance of forage sorghum and Sudan grass in animal nutrition. Peculiarities in production technology with respect to utilization, crop rotation, tillage, fertilization, time and mode of sowing as well as crop mowing are taken into consideration. Production in irrigation conditions have also been analyzed, such as the effect of irrigation on green forage yield, plant water requirements and preirrigation soil moisture.
AB  - U radu su razmatrane specifičnosti u tehnologiji proizvodnje krmnog sirka i sudanske trave sa aspekta načina iskorišćavanja, počev od izbora preduseva obrade zemljišta, đubrenja, vremena i načina setve, do košenja useva. Takođe analizirane su specifičnosti gajenja ovih biljnih vrsta u uslovima navodnjavanja sa aspekta potreba biljaka za vodom, racionalnog režima zalivanja i efekata navodnjavanja na ostvarene prinose zelene mase.
