Agri-environmental conditions of the soybean yield formation

Abstract

In order to identify the degree of dependence of crop on environmental factors needed for the formation of high productivity, an assessment of influence of agro-ecological conditions on grain yield formation of soybean in crop rotation was conducted. The article presents the results of a comparative analysis of soybean productivity, starting with 1963, the influence of hydrothermal conditions in July and in August (the period of flowering and ripening of beans), the content of labile 2O5, their relationship and contribution of each of these factors to yield formation of soybean varieties depending on forecrop (soy-oat mixture and wheat).
