Zvedeniuk T. The productivity of five-course grain rotation with using different basic cultivation methods of gray forest soil of the Right-Bank Forest-Steppe zone

Object - the process of changing fertility indices of gray forest soil, weed-infestation of sowing and yield formation with prolonged use methods of basic tillage and use crop residue as fertilizer. The goal of research is establish the basic laws of formation of crop productivity and gray forest soil fertility under different systems of basic cultivation with use of crop residue as fertilizer, optimal doses of mineral fertilizers in shot-term crop rotation of Right-Bank Forest. Methods - field, laboratory, quantity and weight, biochemical, calaulation-comparative, mathematical and statistical. Scientifically grounded application of differentiated system of basic soil tillage to improve soil fertility by use of crops residue on a background of mineral fertilizers in order to create sustainable yilds - 4,4-4,5 t / ha of grain units. Main research results implemented in 2013 and 2014 yr in the farms of Kyiv and Khmelnytsky region on a total area of 700 ha. Areas of use is agricultural production.
