Abstract: In agriculture, it is important to increase labor productivity, improve technological processes, and reduce costs as much as possible, save available resources. The purpose of the study is to scientifically substantiate the impact of seedling thickness and fertilization standards on cotton yield in the cultivation of cotton by sowing seeds under the film in light gray soils of Namangan region. The experiment consists of 6 options 3 turns, seedling thickness 138, 110, 90 thousand bushes / ha, application of fertilizers in the 1st norm pure nitrogen 210 kg per hectare, phosphorus 125 kg, potassium 105 kg 2nd norm nitrogen 250 kg per hectare, phosphorus 150 kg, and 105 kg of potassium were studied. In this method, the growth and development of plants is accelerated in the cultivation of cotton. The yield of cotton is also the highest (39.7 ts / ha) in the variant used in the norm N-250, F-150, K-125 kg / ha, leaving the seedlings at 110 thousand bushes / ha. K-105 kg / ha was 1.6-2.3 ts / ha when used normally, N-250, F-150, K-125 kg / ha was 2.7-3.8 ts / ha when used normally. When the thickness of seedlings is 138 thousand bushes / ha, the yield of cotton decreases slightly when applied in the norm of N-200, F-125, K-105 kg / ha 33.6; N-250, F-150, K-125 at the normal application rate was 36.3 ts / ha.
