The influence of moistening conditions and seed treatment with biological preparations on the growth and yield of winter wheat varieties

Purpose. To determine the influence of moistening conditions and treatment seeds with biological preparations Azotofit-r, Fitotsyd, Mycofriend-r, Orhanik-balans Monofosfor on growth processes at initial plant life stages, formation stand density grain yield winter wheat varieties. Methods. General scientific, special, field, mathematical-statistical calculation-comparative methods were used for research. Results. The key to a high is in obtaining even stands, forming optimal stands time harvesting, taking into account their survival rates, coefficient productive tillering, study new varieties adapted climate changes. According research results, it was determined that, average, 2020–2022, highest among studied recorded plants variety ‘Duma Odeska’ (8.38 t/ha) under irrigation variant pre-sowing biopreparation which 0.78 t/ha more compared control (treatment water). In without irrigation, 6.08 t/ha, less than by 2.3 or 27.4%. Conclusions. developed elements technology growing make possible form significantly increase Southern Steppe Ukraine
