The article provides data that the depth of groundwater located at 2-2.5 m above sea level in the moderately saline meadow-alluvial soil of the Bukhara region of the Republic of Uzbekistan, which is applied in agriculture immunostimulant contact and triple action - “Zerox” norms (1 - 2 - 3 l / t; 1 - 2 - 3 l / ha + surfactant 0.15 l / ha) and terms (in pre-sowing treatment of seeds, in the appearance of 2-4 true leaves, budding and flowering) of cotton vegetation , and in various densities (80-90; 100-110; 120-130 thousand pcs. bush / ha) standing, the highest yield (52.5 c / ha) and quality (fiber length 35.3 mm; fiber yield - 40% and 22.6% oil content) fiber and seed oil content were obtained when using Zerox at 2 l / t; 2l / ha + surfactant 0.15 l / ha at a plant density of 80-90 thousand pcs. bush / ha, which leads to high economic efficiency, the share of the first harvest (28.7%) and the constituent crop additives (by 11.7 c/ha), the quality (1.1 mm; 2.5%) of the fiber and oil content of seeds (1.5%) more than the control variant.
