| Abstract (English): |
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 < 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 reima navodnjavanja oroavanjem 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 istraivana su po tri reima navodnjavanja, i to sa 80-85% (T1), 70-75% (T2), 60-65% (T3) poljskog vodnog kapaciteta i prirodni vodni reim 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 fizioloku aktivnost biljaka, vegetativni rast i produktivnost soje. Navodnjavani tretmani su vrlo značajno (P < 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 reimi imali su statistički značajno različite uticaje na komponente prinosa kao to su visina biljaka u vreme etve, 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.
