Analysis of a complex of agricultural activities and productivity of cotton varieties Ganja-182 and Beyaz-Altun-440 in Azerbaijan

When cultivating cotton, it is more effective to use an optimized set of agrotechnical measures to obtain high and high-quality yields from one area. This goal can be achieved if the sowing dates, thinning and planting density are observed in accordance with the appropriate agrotechnical rules. Depending on the use of a set of agrotechnical measures in the variant with a sowing pattern of 74 thousand plants (90x15x1) of the Ganja-182 variety, sowing on April 20, fertilization and thinning on May 10, the number of bushes is 12, which is 5-7% more than in other variants. The Beyaz-Altun variety had slightly lower indicators. This variety also had a higher yield of 74,000 plants (90x15x1) with a sowing pattern of April 20 and May 20 thinning, with 9 bushes. The raw cotton weight per boll, the number of bolls per bush, the fiber yield, and the weight of 1,000 seeds were higher for both varieties with a sowing pattern of 74,000 plants (90x15x1), sowing on April 20, and thinning on May 10.
