PRODUCTION OF WINTER WHEAT IN THE PHASES OF THE SOLAR ACTIVITY CYCLE.

The impact of the phases of the solar activity cycle on winter wheat production in different physiographic zones of Ukraine: Polesie, Forest-Steppe and Steppe have been researched. Particular attention is paid to indicators of yield that have a significant impact on the development of agricultural industries. A correlation dependence between the yield of winter wheat and the phases of the cycle of solar activity was established. With a proper research of these indicators, the sectoral structures of agro-ecosystems can predict for income or prevent the growth of zonal costs in social production. The optimal periods for obtaining high and stable yields of the studied culture connected with the physical factors of nature are determined. That is why a large role is played by the scientific understanding and practical use of each individual phase of the solar activity cycle in agroecosystems, which enables a business entity to obtain a reasonable dynamic system by their periodic changes. At the same time, and is a prerequisite for control at all stages of culture production. [ABSTRACT FROM AUTHOR]
