Skalyga A. Productivity of fruitshift crop rotation depending on the systems of basic soil till and levels of fertilizing in Ukraine’s central Forest-steppe

1. Object – process of forming and potential realization of crop rotation productivity and indexes and terms of soil fertility under the influence of different basic till systems in the conditions of central Ukraine’s forest-steppe; Purpose – define the most rational system of basic soil till in the five-course crop rotation of central Ukraine’s forest-steppe, which provides a receipt from 1 hectare of plough-land more than 70 centner of forage units at high economic and power efficiency; methods – the field and laboratory; novelty – In the condition of central Ukraine’s forest-steppe the influence of different systems of basic till on physical and chemical properties and microbiological soil activity and productivity of five-course crop rotation with 80% grain-crops satiation is first defined ; results – recommended to production to offer to the economies of the unsteady moistening areas of central Ukraine’s forest-steppe in five-course crop rotation with 80% grain-crops satiation the protracted shallow till system, for meadow clover – shelling on 10–12 sm + N30P30K30, winter wheat – shelling on 10–12 sm + N40P60K60, corn on grain – ploughing on 25–27 sm + 40 ton/hectare of manure + N60P80K80, pea – disk shelling on 10–12 sm + N30P40K40 and barley with meadow clover undersow – shelling on 10–12 sm + P30K30; industry – agriculture.
