PRODUCTIVE CHARACTERISTICS OF SOYBEAN IN AGROECOLOGICAL CONDITIONS OF SREMSKA MITROVICA, SERBIA

Abstract

The objective of this paper was to examine and present the results of soybean grain yield and oil content during a two-year period in agro-ecological conditions of Sremska Mitrovica, Serbia. Data were statistically analysed by analysis of variance, using the method of two factorial trials (variety, year). LSD was used to compare means for significant differences. Significantly higher yields were recorded in 2010 compared to 2009. Average yield amounted to 4,409 kg ha -1 for analysed soybean varieties, and ranged from 3,697 kg ha -1 (2009) to 5,121 kg ha -1 (2010). The average highest yield was found in Victoria variety (4,520 kg ha -1 ). The year 2009 was favourable for oil synthesis. The tested soybean varieties had average oil content of 21.07%. Statistically significantly higher oil content was recorded in 2009 compared to 2010 (p <0.05). The average highest oil content was found in VojvoĊanka variety (21.42%). The tested soybean varieties had average oil yield of 927 kg ha -1 . The average highest oil yield was found in varieties VojvoĊanka and Victoria (957 kg ha -1 , 942 kg ha -1 ). During the analysed period varieties VojvoĊanka and Victoria higher average oil yield compared to Trijumf variety. Yield in soybean grain, 2009-2010, was statistically highly significantly positively correlated with oil yield and precipitation (r= 0.94**, r= 0.92**). Yield in soybean grain, 2009-2010, was negatively correlated with oil content (r= 0.37) and statistically highly significantly negatively correlated with temperature (r= 0.93**).
