Marchenko K. Physiological justification of the use of biological preparations in the technology of growing whole-grain oats in the Right Bank Forest Steppe of Ukraine

As a result of vegetation and field studies, it was established that MBP Melanoriz and RRR Agrolight affect the directionality of metabolic processes in whole-grain oat plants, whose active and direct participants in the plant organism are enzymes. The dependence of the content of chlorophyll in whole-grain oat leaves on the norms of the use of MBP Melanoriz, introduced separately and in a complex with RRR Agrolight, was established. It was found that MBP Melanoriz and RRR Agrolight are able to significantly influence the passage of metabolic processes in plants, which is appropriately reflected in the main stages of cell development (embryonic, elongation and differentiation) and the anatomical structure of individual tissues and organs; with their combined use, a stimulating effect can be traced, which is expressed in the formation of the anatomical structure of the leaf apparatus of the mesomorphic type. The use of biological preparations in the technology of growing whole-grain oats had a positive effect on the growth processes of plants. The influence of drugs on the formation of the root system of plants has been clarified. The obtained data indicate a positive effect of the MBP + RRR complex on growth processes in whole-grain oat plants, which are the result, on the one hand, of the stimulating action of exogenous phytohormones, and on the other hand, the improvement of the mineral supply of the plant organism due to microorganisms introduced into the rhizosphere. The use of the microbial preparation Melanoriz separately and in combination with the plant growth regulator Agrolight in whole-grain oat crops contributed to the activation of the vital activity of certain groups of microorganisms in the rhizosphere of whole-grain oats. Recommendations have been developed on the use of biological preparations in the technology of growing whole-grain oats in the Right Bank Forest Steppe of Ukraine in order to increase the yield and quality of grain.
