At the Samarkand Scientific Experimental Station, in 2025, Xin Lu Zao-78 cotton variety was planted in double rows under the film with a row spacing of 76x10 based on foreign technology. Stom-P Original 33% k.e. containing 330 g/l of pendimethalin was sprayed against weeds. Before sowing, 80-100 percent of the annual rate of phosphorus fertilizers (250-300 kg/ha in physical form of ammophos) and 80-100 percent of potassium fertilizers (100-120 kg/ha of potassium chloride) were applied under the chisel-harrow. Water-soluble NPK fertilizers were applied in solution through drip irrigation according to the recommendations. During the season, irrigation was carried out at a rate of 930-1155 m³/ha.
