The purpose of research is to develop and implement in the production of zonal systems of rotary crop rotations for the production of competitive products in market conditions. Research methods - long-term field, laboratory-field, vegetation experiments, laboratory research (chemical, physico-chemical, microbiological). The soil is a typical shallow low-humus coarse-grained coarse-grained soil. Crop rotations provided productivity: harvest from 1 ha of crop rotation area: 4.06, fodder units - 7.57, grain units - 6.52 and digestible protein - 0.68 t. The highest yield of food grain (3.02 t / ha) provides six-crop rotation: buckwheat - winter wheat - soybeans - spring wheat - winter rye - barley. It is established that 7-8-field crop rotations are 57.2-62.5% saturated with grain crops in terms of grain yield, feed and grain units are inferior to 4-5-field crop rotations by 80-100% saturated with grain crops. Relatively net profit was 17.65-24.53 thousand UAH / ha, profitability was 77-159%. Product Description popup.authors Bakumova Maryna V. Batrak Nadiia V. Boyko Petro I. Kalchun Tetiana R.
