These practices include differentiated moisture regimes, varying row spacing, nitrogen fertilization, seed treatment with biological growth regulators, as well as modern methods of variance, correlation, and economic analysis for objective verification of the results. This allowed, in 2025, to identify and scientifically substantiate the most efficient maximized irrigation model for obtaining maximum profit. This model involves complete moisture supply (maintaining soil moisture at 60% of field capacity throughout all growth stages), a row spacing of 45 cm, N45 fertilization at the stem elongation stage, and seed treatment with the biopreparation "Shchedra Nyva HV". Due to the synergy of these factors, the model ensures the highest seed yield – 0.27 t/ha – and a record profitability level of 253.4%. Scientific and methodological recommendations for the formation of models for high-quality planting and seeding material of bioenergy crops and raw materials for biofuel production in non-irrigated and irrigated lands of southern Ukraine have been developed.
