The purpose of research - development and introduction of zonal systems of crop rotation with a short rotation for the production of market conditions, competitive products. Research methods - long field, laboratory and field, pot experiments, laboratory tests (chemical, physical and chemical, microbiological). The soil - black soil typical shallow. A model for the saturation short crops rotation of 50 to 100% technical 20 to 50% for cereal 20-33,3 % and application of intensification (mineral and organic fertilizers, crop protection chemicals ). Crop rotations provide performance : the collection of 1 ha of crop rotation area : grain - 3,90-5,70 t feed units - 7,5-9,2 tons of digestible protein 0,65-0,80 m, the yield of winter wheat - 5 ,10 -6 , 10 t / ha , maize - 6,90-9,40 , beet sugar - 43,0-50,0 sunflowers - 3,40-4,00 , soybeans - 2,40-2,70 t / ha. Conventionally net profit of 3900-4900 UAH / ha, profitability was 64-80 %. Product Description popup.authors Єрмолаєв М.М. Єрмолаєва Т.М. Бойко П.І. Борук О.С. Вінничук Т.С. Василенко В.Т.
