Development of irrigation regime of promising autumn wheat variety “Alekseich” under conditions of low-salinity soils of Bukhara region

This article is written based on the experiments conducted on the irrigation regime of autumn wheat variety "Alekseich" in the conditions of low salinity, mechanical composition medium hummock soils of the "Muhammad Ismat" farm located in the Bukhara district, Bukhara region.The article describes the results obtained based on the study of the irrigation regimes of autumn wheat, the influence of the irrigation regime on the amount of salts in the soil, and the growth and development of autumn wheat, grain, and straw yields.Within the framework of scientific research, experiments were carried out on a total of 6 variants.In variant 1, irrigation works were carried out under farm conditions, measuring only the water provided for irrigation.In variant 2 of the studies, however, pre-irrigation soil moisture, in 70-70-65% compared to LSMC, 70-75-65% compared to LSMC in variant 3, 70-80-65% from irrigation in variant 4, and 75-75-65% pre-irrigation soil moisture in variant 5. Also, in variant 6 of the studies, pre-irrigation soil moisture in 75-80-65% compared to LSMC was carried out.While the autumn yield of wheat grain grown in agricultural conditions during scientific research was 6.3 t/ha and 6.0 t/ha in variant 2 of the studies, the average grain yield in variant 3 was 6.1 t/ha.The extraction of experiments pre-irrigation soil moisture, irrigated at 70-80-65% compared to LSMC, in variant 4, the grain yield of autumn wheat was 7.2 t/ha, compared to LSMC in variant 5, and the grain yield of autumn wheat in the irrigated field at 75-75-65% was 6.8 t/ t/ha.Pre-irrigation soil moisture, with an autumn grain yield of 7.1 t/ha in irrigation variant 6 at 75-80-65% compared to LSMC.
