Abstract

The article highlights the peculiarities of growing winter barley crops in the southern steppe zone of Ukraine and its importance in the grain balance of the state. The influence of biological characteristics of the crop and changes in climatic conditions on the productivity of winter barley in different weather factors of growing years is substantiated. The results of research conducted during 2016-2019 yrs on Southern chernozem in the Educational, Scientific and Practical Center of MNAU with four varieties of winter barley are presented. The research was devoted to improving the nutrition of crops based on the principles of resource conservation by using modern biopreparations in the main periods of vegetation of winter barley plants for foliar treatments of crops of varieties taken for study. Studies determined the influence of various types of biopreparations and the period of top dressing on the growth and development of winter barley plants, the formation of productivity in the context of varieties, technology elements and years of cultivation, which differed in climatic conditions. The positive impact of the use of biopreparations on the growth processes of plants and the yield of winter barley grain was established, the most productive varieties, the best biopreparations and the timing of foliar top dressing were determined
