Savranska L. Basic treatment of the podzolized chernozem under spring rape after winter wheat in the conditions of the right-bank Forest-Steppe zone

Subject of research - the process of spring rape productivity formation at different basic tillage mathods and depths after winter wheat, economic and energy characteristics of the crop growing technology. The purpose - to determine an influence of different depths of moldboard ploughing and blade loosening in the right-bank Forest-Steppe of Ukraine on the condinions of growing and productivity of spring rape seeds after the winter wheat and to give an economic and energy evaluation of these components of technology. Methods of research - field, laboratory, mathematical-statistical, computational and comparative. The expediency of substitution of the traditional energy-intensive moldboard ploughing for blade loosening with simultaneous decrease of its depth from 20-22 up 15-17 cm in the system of autumn cultivation of the podzolized chernozem under spring rape after winter wheat is substantiated. Recommendations to production are developed concerning the application of blade cultivation of the podzolized chernozem under spring rape what will secure the equivalent crop harvest compared to the traditional moldboard ploughing and will allow to economize 29-32%of all kinds of expenses for the basic treatment of soil. The research developments are introduced in 2005 in the Cherkassy region over an area of 64 ha. The sphere of application - the agricultural production.
