ВИВЧЕННЯ ВПЛИВУ БІОПРЕПАРАТІВ ЗА РІЗНИХ НОРМ ВНЕСЕННЯ НА ПРОДУКТИВНІСТЬ ПШЕНИЦІ ОЗИМОЇ В УМОВАХ ПІВНІЧНОГО СТЕПУ УКРАЇНИ

The article investigated the effect of biological products for different application rates on the productivity of winter wheat in the northern steppes of Ukraine. The technology of growing winter wheat has been determined, which is based on optimizing a huge number of different conditions that affect the formation of high grain productivity of the required quality. Growing technologies pay great attention to sowing dates, which directly affect not only the quantity and quality of the crop, but also the formation of plant resistance to many adverse factors. The weather conditions on which the studies were conducted are analyzed. The biometric indicators of winter wheat plants were revealed, namely: tillering coefficient, coefficient of secondary roots, number of grains in an ear, weight of a thousand seeds. The yield of winter wheat was determined depending on the proposed experimental design.
