Ecologization of crop industry by introducing a bean component into the field crop rotation of Western Siberia

Abstract

Abstract The paper studies field crop agrophytocenoses and their productivity in multi-year field experiments. Accompanying measurements and observations of crop rotations in the southern forest steppe zone of Western Siberia were carried out using the method of state crop testing and methodological instructions of B.A. Dospekhov. The soybean grain quality was determined according to GOST 10846-91 Grain and its processing products. Method of protein definition; GOST ISO 5983-2-2016 Fodder, compound feeds, compound feed raw materials. The mass fraction of nitrogen was determined and the mass fraction of crude protein was calculated. Sibiryachka soybean variety was used in crops. The experience has shown that the maximum accumulation of humus is ensured by crop rotation alternation. The use of complete fallow in rotation increases the productivity of the whole crop rotation to 2.36 t/ha with feed unit content amounting to 3.87 t/ha. Crop-replacing rotation differ from each other in productivity, however, the inclusion of oilseed crop in the scheme allowed balancing the content of feed units. The rotation of crops and the place of soybean in crop rotation significantly affected its yield. Protein accumulation does not depend on rotation and a set of precursors.
