Boris N. The productivity of corn with using different basic soil cultivation methods and sowing in a grain short crop rotation of the Right-Bank Forest-Steppe.

The object of the study is the process of changing the water-physical, agrochemical and biological parameters of gray forest soils, the influence of seeding methods on growth, plant development, the formation of corn yield and the productivity of grain rotation, depending on the main soil processing systems and the use of by-products on fertilizer. The aim of the work was to establish the effectiveness of various methods of basic treatment of gray forest soil and the influence of the sowing method on the growth, development and productivity of corn in the conditions of the Right-bank Forest-Steppe. Methods - field, laboratory, measuring-weight, comparatively-calculated, mathematical-statistical. The use of chisel loosening of soil to a depth of 43-45 cm in a differentiated main processing system in a short-rotation grain rotation is scientifically justified, which contributes to a decrease in the differentiation in the fertility of the 0-40 cm layer, provides an 11% higher crop productivity level relative to other non-waste treatments and is economically and energetically feasible. For the first time for the conditions of the Right-bank Forest-Steppe, the expediency of applying a combined seeding method is substantiated, the regularities of its influence on the temperature regime of the soil and the peculiarities of the formation of the yield of maize plants are established. Scientific developments to optimize the methods of basic soil cultivation introduced in 2016 PE "Agrarian" Volodarsky district of the Kiev region on an area of 500 hectares annually. The implementation of the completed research and development to optimize the ways of sowing maize was carried out in 2014-2016. In the NSC "Institute of Mechanization and Electrification of Agriculture" NASA on a total area of 50 hectares. The field of application is agricultural production.
