Abstract

The article shows that the productivity of spring wheat is determined by the total effect of a set of conditions, each of which affects the amount of products obtained. As a result of the research, it was found that the yield of spring wheat directly depends on the hydrothermal conditions of the growing season. The key factor affecting the increase in the productivity of crops when using mineral fertilizers is the amount of precipitation during the growing season. The use of mineral fertilizers can significantly increase the yield of spring wheat, reducing the negative effect of the hydrothermal conditions of the growing season. So, when N₆₀P₃₀K₆₀ was introduced, the yield increase in different climatic conditions of the research years was 9, 3 … 92, 8%. It was also found that the reproductive function of durum spring wheat is characterized by the fact that the total number of caryopses of a shoot spike and their total weight are in close proportional dependence on the value of its vegetative mass. In this case, the value of the grain-straw ratio is a consequence of the proportional dependence of the reproductive elements of the shoot (acceptors) of wheat on the size of its vegetative (donors) organs.
