Effect of Cotton Maturity Degree on Changes in Fiber Quality Indicators

the research was carried out in the field of the REEL technical engineering agrocluster in the Orta Chirchik district. For this, cotton plants with a distance of 100x100 meters were selected. First, the first bolls opened on the cotton after defoliation were harvested, then bolls weighing about 1 kg, ripened for 3 days, 6 days, 9 days and 12 days, were harvested. The peeled bolls were separated from the fiber by hand. The physical and mechanical properties of the fiber were determined.
