Abstract
The purpose. To determine agro-physical properties and water regime of soil at different systems of basic cultivation and doses of fertilizers, to calculate the level of yield of crops and productivity of crop rotation. Methods. Field and mathematical analysis. Results. Subsoiling systems of basic soil cultivation, and irrigation water form agro-physical properties which are optimum for growing winter barley and partially meet demands of corn and soya bean. Use as fertilizer of all collateral products of crops and increase of rate of application of nitrogen fertilizers from 75,0 up to 97,5 kg/hectare d.w. counting for 1 hectare of crop rotation square with inoculation of seeds of soya bean by Rizogumin promoted increase of productivity of crop rotation for 15,0 — 16,3% c. units according to systems of basic soil cultivation. Conclusions. In the tilling crop rotations on dark-chestnut medium-loamy soils in conditions of irrigation in the South of Ukraine it is expedient to apply system of the differentiated-1 basic cultivation with use as fertilizer of all collateral products and enter fertilizers in dose N97,5P60. That will ensure profit at the level of 10 thousand hrn/hectare, and the level of profitableness 110%.

Key words: method, depth, dose of fertilizers, firmness of build, water permeability.
