Krivenko A. Scientific substantiation of biologized technologies of growing of winter grain crops in the conditions of the Southern Steppe of Ukraine

Object of research - The process of biologization of technologies of growing of winter grain crops under conditions of regional climate change for the Southern Steppe of Ukraine. The purpose of the research is to develop and scientifically substantiate the biologized technologies of winter crop cultivation for conditions of arid southern steppe of Ukraine to reduce anthropogenic loading on the natural environment. Methods of research - bibliographic, abstract-logical, monographic, field, laboratory, calculation-comparative or constructive, mathematical statistics. Research results - For the theory: For the first time, technologies of growing winter cereal crops in short-rotational grain-field crop rotations using sideral vapors were first developed and scientifically substantiated by introducing elements of biologization to reduce the chemical and anthropogenic loading on agroecosystems and to ensure the requirements of a gradual transition to organic farming in conditions of regional climate change . For practice: It is proved that in short-rotation crop rotation it is advisable to introduce busy pairs (winter wick or a mixture of peas with white mustard), shelled and non-polar, shallow soil cultivation, which provide a positive balance of humus and nutrients, allow the formation of high winter wheat yield and grain quality on grades 3-4 depending on the weather conditions, the system of basic cultivation of the soil, as well as the organizational and economic opportunities of the economy. The sphere of use is agricultural enterprises of the south of Ukraine.
