THE EFFECT OF BIOLOGICAL PREPARATIONS ON THE SOWING QUALITIES AND FIELD GERMINATION OF ALFALFA SEEDS

Abstract

Agriculture has been solving the problem of increasing yields through chemical plant protection products. Their intensive use has led to the need for the biologization of agriculture, which means the production of products using the maximum potential of environmental factors to increase yields without harming the environment. Using seeds with high sowing qualities is the key to obtaining sustainable yields. In this regard, this article presents the results of research on the effect of pre-sowing treatment of alfalfa seeds with Organit P, Organit N, Biodux, Systemica M biopreparations, OrganitN+ OrganitP+Bidux for sowing qualities and field germination. The experiments were carried out in 3-fold repetition, observations were made according to 6 variants of the experiment. Laboratory experiments were conducted according to the methodology for determining the growth strength of seeds of forage crops according to GOST 12038-84. The flow rate of the working fluid for seed treatment was taken at the rate of 1 ml per 100 g of seeds. Germination energy was determined on the 3rd day, and laboratory germination on the 7th day. The scheme of the experiment included a variant without treatment (control) with the treatment of seeds with biological preparations a day before sowing. It was revealed that the treatment of alfalfa seeds with biological preparations improves the indicators characterizing the initial stages of plant growth and development ontogenesis. Regarding germination energy, the highest result was shown by the preparations Systemica M–75,0% and Organit N+ Organit P+ Bidux – 68,5%. Using the Organit N+ Organit P+ Bidux complex of drugs increased laboratory germination to – 81,5% and field germination to – 41,5%.
