BUCKWHEAT YIELD UNDER BIOLOGIZED FERTILIZATION SYSTEM IN ORGANIC PRODUCTION

The article substantiates the relevance of research in the field of organic production, which results in environmentally friendly products. It is noted that the demand for organic products both in the world and in Ukraine is constantly growing, which stimulates producers to increase their volumes using the latest technologies that meet the requirements of organic production. This is especially true for such a valuable cereal crop as buckwheat, which is used as a dietary medicinal product. A comprehensive assessment of the biologized system of buckwheat fertilization is scientifically valuable and relevant in today's conditions, which will allow obtaining high-quality environmentally friendly products. The effect of the use of a microbial preparation and an organic fertilizer-biostimulator on the formation of buckwheat productivity under organic cultivation technology in the soil and climatic conditions of the Western Forest-Steppe was studied. It was determined that bacterization of buckwheat seeds before sowing and foliar feeding with biofertilizer had a significant effect on the growth and development of plants and their productivity. In particular, treatment of buckwheat seeds with the nanocomposite complex bacterial preparation Azogran (108 cells/ml) and two-time spraying of buckwheat crops with the liquid organic fertilizer-biostimulator Vermimag contributed to a decrease in weediness of crops, an increase in the mass of 1000 seeds, grain quality, which ensured an increase in buckwheat yield by 0.57 t/ha, or by 46.0% relative to the control. Analysis of research results indicates the feasibility of organic buckwheat cultivation with the use of a bacterial preparation for seed treatment and an organic fertilizer-biostimulator for foliar feeding in the fertilization system.
