Lenshin A. Productivity of short-term crop rotations depending on the saturation of grain and row crops in the Right Bank of Forest-Steppe

Object of research is the process of formation of the yield of agricultural crops, and changes in soil fertility depending on the crop rotation with a different share of grain and tilled crops. The study objective was to increase productivity of crop rotations through optimal saturation of grain and tilled crops for soil conservation in the Right Bank of Forest-Steppe. Research methods - field, laboratory, mathematically-statistic, calculations and comparative. For the first time in the north-western part of the Right Bank Forest-Steppe regularities of changes podzolic chernozem fertility, the number of weeds in crops under the influence of crop rotation and crop productivity, depending on the crop pattern, making it possible to identify the most productive short-term rotations for farms with a narrow specialization. Found that the introduction of short-term rotations high concentration crops - up to 75% and an average row crops - up to 25% makes it possible to increase the productivity of crop rotations to 9.7 t/ha of fodder units. Research results are introduced into production in 2011 in the ACC "Reshnivetsky" in Starokonstantinov district of Khmelnitsky region in the area of 400 hectares. Field of applicant of the results of investigation is agricultural production.
