Implementation of research results. Based on the results of a study on two-row sowing on the ridges and the optimal density of standing, as well as the determination of the economic efficiency of the cotton variety "Omad" in the conditions of old-irrigated typical sierozem soils of the Samarkand region:
a recommendation for farms was developed and approved, specializing in cotton growing, a recommendation was developed and approved “Terms and norms of two-line sowing of cotton seeds” (Certificate of the Ministry of Agriculture dated September 21, 2022 No. 07/22-04/6751). Which serves as a benefit for obtaining high and high-quality cotton yields for farms specializing in cotton growing;
the developed agricultural technology for the cultivation of cotton of the Omad variety at optimal standing density in the conditions of old-irrigated typical sierozem soils of the Samarkand region in 2019-2021 was introduced on an area of 53 hectares at the Usto Temir farm, 41 hectares at Firdavs Farrukh Khaydarov Chashmasi 94 hectares (Certificate of the Ministry of Agriculture dated September 21, 2022 No. 07/22-04/6751) according to the results of the experiment, the high efficiency of the cotton variety “Omad” was achieved with row sowing of seeds along the ridges with a density of 140-150 thousand bushes/ha and with double-row sowing with a density of 170-180 thousand bushes/ha;
double-row sowing on the ridges of cotton seeds of the Omad variety with a standing density of 170-180 thousand bushes / ha with the application of mineral fertilizers was introduced in the Usto Temir farm in the Pastdargomsky district of the Samarkand region. (Certificate of the Ministry of Agriculture dated September 21, 2022 No. 07/22-04/6751). As a result, the cotton yield was 37.2-40.8 centners/ha, the total income was 25.3-26.9 million soums per hectare, the net profit was 5.7-8 million soums, the profitability level was 29-41.
