AB  - In Vojvodina region, water deficit during the growing season is a major factor limiting maize production. Therefore, to achieve the ideal soil water content in this region, it is of crucial importance to optimize irrigation. The effects of different irrigation levels with sprinkler irrigation system on crop yield, yield components, water use, water (WUE) and irrigation water use (IWUE) efficiency of maize (Zea mays L) were investigated in Vojvodina (northern Serbia), on a Calcaric Chernozem soil in temperate environment for 3 consecutive years (2006-2008). Maize was subjected to four irrigation regimes, as follows: non limited irrigation (I-100), 75% of non-limited irrigation (I-75), 50% of non-limited irrigation (I-50), and rainfed (non-irrigated) as the control (I-0). The irrigation treatments were arranged in a complete randomized block design with 4 replicates. Results showed that maize grown in rainfed conditions had high annual variability, mainly due to amount of rainfall and its distribution during the crop-growing seasons. A significant irrigation effect was found for yield, yield components and others investigated parameters under study. Water stress had significant impact on yield response: as an average of the three years, a grain yield increase of 47.8, 32.8, and 22.9% was observed in I-100, I-75 and I-50 treatments compared to rainfed (I-0) treatment, respectively. Yield increased linearly with seasonal crop evapotranspiration and irrigation amount. Furthermore, WUE is maximized with a moderate water deficit (I-50), while IWUE is the highest in I-100 treatment. The deficit irrigation stress index, DISI, decreased with increasing irrigation rate. The results revealed that irrigation is necessary for maize cultivation because rainfall is insufficient to meet the crop water needs in Vojvodina. In addition, the study indicated that the irrigation regime of 25% water saving (I-75) could ensure satisfactory grain yield of maize and increment of WUE.

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  - 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.
