Productivity of winter wheat depending on phytohormonal regulation

Abstract

   Phytohormonal regulation with the help of BAV (bio-power and binorama) helps to increase the yield of winter wheat – up to 4.13 t/ha, reduces losses during harvest, reduces the amount of fungicides and herbicides used, increases the assimilatory surface of the leaves and increases the coefficient of utilization It is photosynthetically active radiation. when applying nitrogen-phosphorus fertilizers in the dose of N60P40 and N90 P60, the coefficient of use of the incoming FAR increases by 1.0...1.2 and 1.2...1.4%, respectively, compared to the unfertilized variant [2]. The biological basis of the production management of the productive activity of cultivated crops are the natural processes of plant growth and development, which are regulated by substances produced by the plant itself (endogenous phytohormones). Most of the synthetic growth regulators are either physiological analogues of endogenous phytohormones, or act by changing the hormonal status of plants, which do not produce toxic effects in the concentrations used, and are not a source of nutrition [5].
