Abstract
The article presents the results of studies of spring barley of different varietal composition (Helios, Stalker) under the influence of sowing methods (ordinary row (15 cm), narrow-row (7.5 cm)) and seeding rates (3.5, 4.0, 4.5 and 5.0 million germinating seeds per hectare) in the Southern Steppe of Ukraine. Our data show that the optimal seeding rate in the experiment was sowing with 4.5 million germinating seeds per hectare using a narrow-row sowing method for the mid-season variety Helios. This variant ensured the formation of 3.60 t/ha of grain, conditional net profit of 12895.00 UAH/ha and a profitability level of 120.7%.
