The purpose of research - development and introduction of zonal systems of crop rotation with a different 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 different crops rotation of 62,5 to 100% technical 20 to 42,9% 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 - 4,53-7,08 tons, feed units - 8,0-11,8 tons of digestible protein 0,64-1,17 m, the yield of winter wheat - 5,59-8,03 t / ha , maize - 5,8-9,3 , sugar beet - 35,3-46,5, spring barley - 4,74-7,79, sunflowers - 3,64-4,55 , soybeans - 2,56-2,7 t / ha. Conventionally net profit of 4.64-4.94 thousand / ha, profitability was 59-62%. Product Description popup.authors Єрмолаєв М.М. Єрмолаєва Т.М. Бойко П.І. Василенко В.Т. Кальчун Т.Р. Літвінов Д.В.
