In this article, the influence of the non-traditional legume Crotalaria (Crotalaria juncae L.) as the main crop on its growth, development and productivity in conditions of degraded meadow alluvial soils of Khorezm region Autographed Mini-Helmets is described.That is, the highest indicators of seed germination were observed on May 1-5 of crotalaria in the version where 18 kg/ha of germinating seeds were planted, and increasing the sowing rates in all planting periods increased seed germination by 3-5%; as of July, when crotalaria was planted on April 20-25, the plant height was 10-14 cm higher than the options planted in other periods; in the case of September, when the plant was planted at 14 kg/ha on April 20-25, the number of leaves formed was 265.0, which was 85.0 more than when planted early and 15 more than when planted late, and the number of leaves when 14 kg/ha of seed was planted was 10 85.
0 units per kg/ha compared to the variant planted with seeds, 111 units compared to the variant planted with 18 kg/ha; the higher seed yield of crotalaria in 20-25.04 when 14 kg/ha of seed is planted is 18.0 t/ha, compared to the option planted in the early period, 5.9 t/ha; 3.7 ts/ha compared to the option planted in the late period; 2.
4 ts/ha compared to the option with 10 kg/ha of seeds; Compared to option 6, where 18 kg/ha of seeds were planted, 4.8 ts/ha of additional grain yield was scientifically justified.Key words: Audio Crotalaria juncae, grassland alluvial soil, legume, duration, rate, fertility, seed, hay, productivity.
