Nakl'oka Y. Tillage under spring barley after winter wheat in the conditions of the southern Forest-Steppe Zone of Ukraine

Dissertation is devoted to the complex study of various methods and depths of the tillage under spring barley after winter wheat in the conditions of the southern Forest-Steppe Zone of Ukraine due to their influence on the change of agrophysical indices of opodzolic black soil fertility, biological activity of soil, choking of sowing, nutritious regime, forming of seeds yield and economic effectiveness of growing spring barley. It is determined that in the conditions of the southern Forest-Steppe Zone of Ukraine under crop rotation with various depth of the main soil tillage on the black heavy loam opodzolic soils under growing spring barley after winter wheat in the system of fall soil cultivation it is recommended to use the blade loosening instead of mouldboard plowing, the depth of blade loosening is reduced to 10-12 cm without the deterioration of the main agrophysical indices of soil and considerable decrease of sowing productivity
