Sažetak
Soybean as wide spread crop in eastern Croatia is planted on 45888 ha with grain yield 2.0 t ha-1. The treatments in the field trials were growing season (GS, main factor, A: A1=year 2010 ; A2= year 2011 ; A3= year 2012), irrigation rate (IR, sub factor, B: B1=control, no irrigation, B2= soil water content maintained from 60% to 100% of field water capacity (FWC), B3= soil water content maintained from 80% to 100% of FWC) and soybean varieties (sub sub-factor, C: C1=Lucija, C2=Vita, C3=Ika and C4=Tena, created at Agricultural Institute Osijek). The objective of this study was testing irrigation and genotype impact on grain yield, oil and protein content at the soybean in the no nitrogen fertilization soil conditions. Therefore, the nitrogen potential in three climatically different growing seasons in natural, field conditions has been tested. Mean soybean grain yields were 3436 kg ha-1, 3678 and 3633 kg ha-1 in year 2010, 2011 and 2012, respectively. Irrigation and soybean variety had statistically significant impact on soybean grain yield, while growing season not. Growing season, irrigation and soybean variety resulted by statistical significant impact on oil content, while growing season on protein content, only.
