Substantiation of agroecological factors on soybean agrophytocenoses by analysis of variance of the Right-Bank Forest-Steppe in Ukraine

In the article agroecological factors of competitive bioorganic varietal technology of soybean cultivation which provides development of regulations of application of a complex of alternative types of fertilizers for their cultivation in the context of short-term and long-term action and basic superstructure of factor estimation of block. As part of joint research work of Vinnytsia National Agrarian University and the Institute of Bioenergy Crops and Sugar Beets of the National Academy of Agrarian Sciences of Ukraine, the authors were involved in research theme "Development of methods for improving the technology of growing legumes using biofertilizers, bacterial preparations, foliar fertilizers and physiologically active substances". To establish the reliability of yield data by analysis of variance, it was determined that LSD 0.05 for factor A in 2017 was 0.09 t/ha. The largest deviations of yield indicators to control among varieties were: variety Podilska 416 +0.41 t/ha, variety Chernivtsi 9 – 0.27 t/ha and variety Agate -0.66 t/ha, which exceeded the value of LSD 0.05 for the factor A (soybean variety) by +0.32, – 0.18 and – 0.57 t/ha, respectively.
