Influence of basic soil treatment methods on productivity of various links of grain crop rotation

Crop rotation in agriculture plays an important role. It provides a certain opportunity to assess the state of agricultural production, to analyze the elements of agricultural technologies used in specific natural and climatic conditions, to identify drawbacks, if any, and reasonably direct them towards optimization. The article discusses topical issues of increasing the productivity of field crops in the links of crop rotation against the background of their placement in various ways of the main processing of merged leached chernozems. During 2016–2019 agricultural years studies were carried out to establish the optimal method of soil cultivation and determine the proportion of the influence of predecessors on the productivity of the main crop of the foothill zone of Adygea – winter wheat, in various links of the crop rotation. According to the results of the research, different efficiency of the considered links of graintilled crop rotation was established. So, higher indicators of crop rotation yield and the total yield of fodder units would be achieved against the background of plowing to a depth of 22–24 cm. If we judge the productivity of a particular link in the crop rotation by the yield of winter wheat, it should be noted that in the link «soya-winter wheat», it was maximum and amounted to 4,90–5,86 t/ha, and the average productivity of the unit was 4,80 t/ha of feed units.
