Abstract
Purpose. The purpose of the study is to substantiate the importance of alfalfa as one of the key crops in agriculture, which requires improvement of technologies for growing new synthetic varieties. Methods. Field, laboratory, visual, measuring, weighing, quantitative, trial sheaf method, mathematical, statistical. Results. Innovative aspects of the technology for growing seeds of new synthetic varieties of alfalfa seed have been developed by pre-sowing treatment of seeds with bacterial preparations Rhizobofit and Rice P with foliar feeding during the growing season with chelated microfertilizers Ecoline Bean and Rist Humate Potassium to improve the fixation of atmospheric nitrogen by nodule bacteria and the mobilization of macro- and microelements from the soil against the background of the main fertilizer for the cover crop with mineral and limestone fertilizers. In the conditions of 2021-2023. This ensured the maximum yield of alfalfa seeds depending on the varieties (405-451) in the first and second years of use. Conclusions. It was established that when growing alfalfa seeds of new synthetic varieties with high sowing and yield properties, the most effective is to carry out pre-sowing treatment of seeds with bacterial preparations in combination with chelate-based microfertilizers twice in the budding phase and the beginning of bean formation against the background of the main mineral nutrition N30P90K90 and fast-acting limestone fertilizer Ca(OH)2 (slaked lime - fluff) - 0.5 norms for hydrolytic acidity, which contributed to an increase in seed yield on average over the years of research by 101-117 kg/ha or 31-35% compared to the control without seed treatment and foliar feeding.
