DYNAMICS OF ACCUMULATION OF NUTRIENTS IN PLANTS OF WINTER WHEAT AND THEIR REMOVAL WITH THE HARVEST UNDER THE INFLUENCE ORGANIC - MINERAL FERTILIZERS

In recent years, great importance has been attached to the study of the dynamics of accumulation and removal of nutrients with crop yields. In the presence of such data, it becomes possible to regulate plant nutrition more purposefully, to obtain a high and high-quality yield, while improving soil fertility. It has been established that about 35-60% of dry matter in winter wheat plants accumulates during the first half of the growing season / before heading /, and 50-65% - in the second. The dynamics of the accumulation of dry matter is largely affected by the content of mobile soil nutrients and climatic conditions. Mineral fertilizers also influence the growth and development of winter wheat plants to a certain extent.
