KUNGABOQAR URUG‘INING SIFATINI OSHIRISHDA EKISH SXEMASINI MAQBULLASHTIRISH

On the irrigated lands of Uzbekistan, 28-30 thousand hectares of sunflower are grown every year. Supplying such a large area with seeds is an urgent issue. In the scientific article, the effect of sowing on seed quality in different schemes (70x40-1, 70x50-1, 70x60-1, 70x70-1 cm. and 60x40-1, 60x50-1, 60x60-1, 60x70-1 cm.) was studied in primary seedbeds for the cultivation of high-quality elite sunflower seeds. The best and best seeds in terms of quality indicators of the variety were obtained when the plant was grown in a large planting scheme (70x60-1 and 60x60-1 cm.). In order to study the after-effects of the planting schemes or the yield obtained in the next generations, the seeds grown in different planting schemes in 2019-2020 were planted in the same soil conditions in 2020 and 2021, and the seed germination and yield were determined. In the indicators after the impact, the SamQXI 20-80 variety in the planting scheme 70x60-1 - 36.3 ts/ha. It was found that the yield of cha and SUR variety was up to 31.2 t/ha due to planting in 60x60-1 scheme.
