Abstract

Two-year survey was conducted according to the principles of organic and conventional dryland cropping technologies. Experiment was placed in Backa Topola, on calcareous chernozem with wheat as preceding crop. In ecological production basic soil fertilization was performed with 15 t∙ha-1 cowshed manure, and in conventional production as pre-sowing treatment was applied 100 kg N∙ha-1. In both years were similar weather conditions. Examination factors were production ways and application of microbial fertilizer. Microbial fertilizer was in liquid state and it contained various types of microorganisms. Data were processed by twofactorial split-plot experiment variance analysis method, and differences between treatments were analyzed by LSD-test. Correlation analysis was conducted. The aim of this work was to determine yield of organic and conventional cropping technologies and correlational dependency between surveyed characteristics. The average yield was statistically very significantly higher (p<0.01), for 24.09% in conventional production compared to ecological production. However, in the world, the average price of organic soybean (Anonymus, 2014a), is higher in comparison with prices of soybean from conventional production (Anonymus, 2014b). The highest yield was reached in variations with microbial fertilizer soil treatment and in phenophases at the beginning and during the flowering. Number of pods was in a strong (p<0.01) positive correlation with number of grains, and grain weight per plant with yield. Strong negative correlation was faund between number of grains and 1000-kernel weight (-0.76). Ecological soybean production, as production system with respect of environmental principles and standards, as well as specific local agroecological conditions, has its priority
