Abstract. The article describes the work of a number of scientists of the Russian Federation on the effect of rye on the structure of the crop, the timing of its sowing and the rate of fertilizer application. In our experience, it was noted that some elements of the crop structure decreased due to plant deposition, with an increase in the rate of mineral fertilizers when sowing rye in the early (1.10) terms under the conditions of Vakhsh 116 variety. We see that the mid-season sowing options are higher than the early-ripening and late ones. The lowest indicator for this variety was observed in late (1.11) varieties of sowing. In the Waterfall variety, plant dormancy was observed relatively rarely and did not adversely affect some elements of the crop structure. The sowing date for both varieties is October 15, and the rate of mineral fertilizers was high when N180P110K90 kg/ha was applied.
