The highest yield was provided by the film spring barley variety Sviatomikhailivsky and after soybeans on the background of N30Р30K30 at the rate of seed sowing of 4.5 million sh. of seeds per 1 ha, it was 5.33 t/ha, after sunflower – 4.50 t/ha (N60Р60К60 and 4.5 million seeds per 1 ha). The increase compared to the control was 1.16 t/ha (27.9%) and 1.23 t/ha (37.4%). Higher yield of 5.35 t/ha of spring barley after soybeans against the background of post-sowing application of N10Р10К10 in the option of foliar fertilization Urea (10 kg/ha) + Magnesium sulfate (2 kg/ha), after winter wheat – 3.53 t/ha, Avangard R for grain (2 l/ha), sunflower - 4.34 t/ha, Urea (5 kg/ha) + Magnesium sulfate (2 kg/ha) + Avangard R for grain (2 l/ha); corn for grain - 3.55 t/ha, magnesium sulfate (2 kg/ha). When growing ordinary spring barley seeds after soybeans on a background without fertilizers, the higher conditionally net income of UAH 24,574/ha (profitability 144.5%, yield 4.62 t/ha) was provided by the Nugget variety at a seeding rate of 3.5 million sh. seeds per 1 ha and the Sviatomikhaylivskyi variety - UAH 24,584/ha, 139.5% and 4.69 t/ha; on the background of N30P30K30 – 23,207 UAH/t, 93.7% and 5.33 t/ha of the Sviatomikhailivskyi variety for sowing rates of 4.5 million sh. seeds/ha; N60P60K60 - grade Krok for norms 4.0 million sh. of seeds per hectare - 17,846 hryvnias/ha, 58.4% and 5.38 t/ha.
