The article shows the features of the formation of productivity of melilot depending from the seeding rates of cover barley and doses of mineral fertilizers under the saline soils of the Pri-Aral region. Studies have shown that the yield of cover crops is significantly influenced by both the seeding rate, which provides an increase in barley yield by 0.37t/ha, and the application of fertilizers in doses of N30P60 and N60P60, at which the increase was 0.75 and 0.8t/ha, respectively. In general, the formation of a high yield of melilot is provided by the seeding rates of cover barley 2 -3 million./ha and doses of mineral fertilizers-N30R60, with this agrophone significantly reduces the oppressive effect of cover culture, increases the survival rate of melilot plants by 10.4-27.5%, leafiness by 12-16. 5%, yield by 22.0-55.1%.
