Soybean oil yield as affected by the growing locality in agro-climatic divergent years

Abstract

The subject of this study are two-year results of the oil yield of six NS soybean genotypes, 0 and I maturity group (MG) at two growing localities (Rimski Sancevi and Sombor in Serbia). Sombor had higher oil yield than Rimski Sancevi (by 119 kg ha-1, i.e. 15.97%). In the locality of Sombor, in 2010, of the oil yields were statistically significantly higher (1.088 kg ha-1) compared to 2009 (640 kg ha-1), which is higher by 448 kg ha-1 or 70% of the average oil yield in 2009. The average oil yield, for all tested genotypes at both locations was 805 kg ha-1, and ranged from 745 kg ha-1 (Rimski Sancevi) to 864 kg ha-1 (Sombor). At both sites significantly higher oil yield was recorded in 2010 compared to 2009. The highest average oil yield at both sites was achieved growing genotype Sava (840 kg ha-1). Sava had highest oil yield (887 kg ha-1) and Balkan (902 kg ha-1) in locality of Sombor. On average for both genotypes and growing localities I MG had higher average oil yield of 29 kg ha-1 ( 3.67%) than 0 MG genotypes. Realizing the potential for soybean productivity depends on genetic factors, the cultural practice implemented, meteorological conditions and the growing localities.
