PRODUCTIVITY AND QUALITY OF RED CLOVER GRASS STANDS DEPENDING ON CULTIVATION TECHNIQUES TECHNOLOGY

Meadow clover (red) is the most important forage crop in most of Russia. The positive qualities of this plant are the presence in the plant tissues of a significant amount of reserve nutrients (crude protein, protein, nitrogen-free extractives), providing high feed value. Meadow clover as a legume plant accumulates organically bound nitrogen in the soil, a large amount of organic mass of crop and root residues, enriching the soil with nutrients and contributing to an increase in its physico-mechanical properties. The disadvantage of culture is its low productive longevity. In this regard, there is a need to intensify cultivation methods in a short period of use in order to obtain the greatest return from crops in the fodder and agrotechnical aspects. Intensification of cultivation methods is everything that helps to increase plant productivity: the application of mineral and organic fertilizers to improve mineral nutrition, inoculation of seeds before sowing to mobilize and activate soil microflora and productive symbiosis of plants and microbiota, the use of growth regulators to directly influence the optimization of photosynthesis processes. The study of the influence of these intensification techniques served as the purpose of our research. It was found that the use of calculated doses of mineral fertilizers most optimally contributed to the processes of crop formation and final productivity of clover herbage. Of the variety of nodule bacteria inoculant strains studied, strain 348a was the most effective because it is species-specific for meadow clover. A positive technique that ensures optimal plant growth and development during the growing season is the use of growth regulators Ribav Extra and Root Super. The studied techniques also had a positive effect on the seed productivity of clover plants, increasing the yield and quality of seeds.
