Efficiency of the basic soil tillage and fertilizer system at growing spring wheat in the conditions of Precarpathian region

Within 2016‒2018 Kalussky district of the Ivano-Frankovsk area (Ukraine) cultivation of wheat summer kinds of Klarisa on sod-podzolic bedrocks in короткоротационном a crop rotation is investigated. It is positioned that application of the organic fertilizers received on a yield of the biogas equipments, at organic and organo-mineral fertilizer systems at all means of the basic treatment of sod-podzolic bedrock improved its agrophysical, agrochemical and biological properties that considerably influenced yield increase and quality indicators of grain of wheat summer. So, at an organic fertilizer system on a variant of a surface treatment of bedrock (depth of 8‒10 sm) productivity of wheat summer has compounded a discing 5,28 т/hectare, or on 2,43 т/hectare more than on control, indexes of the contents of protein, клетчатки, glassiness was above accordingly on 1,9%, 1,6% and 22% of indexes of a control variant. By the economic assaying it is defined that entering of the organic fertilizer received on offered technics, in an organic fertilizer system in a dose 40 т/hectare and in organo-mineral ‒ 20 т/hectare + N40P30K40 at all means of the basic soil cultivation has provided augmentation of conditional net profit, has raised level of profitability and has reduced the cost price of grain of wheat summer. The highest conditional net profit 13878 UAH/hectare, or on 8106 UAH/the hectare is more than control, the cost price 2872 UAH/т, or on 602 UAH/т below control, were on a variant of an organo-mineral fertilizer system (the dung of pigs received on a yield of the biogas equipment in a dose 20 т/hectare + N40P30K40) on a surface treatment of bedrock (a discing depth of 8‒10 sm). On this variant profitability compounded on 33,3% more than the control. On the basis of field and laboratory explorations it is positioned that application of new kinds of organic fertilizers at organic both organo-mineral fertilizer systems and various means of treatment of sod-podzolic bedrocks positively influenced on their agrochemical, agrophysical and biological properties that promoted enriching of growth and development of plants during all season of their vegetation, provided yield increase on 1,91‒2,43 т/hectare in comparison with control and enriching of quality indicators of wheat summer kinds of Klarisa
