Abstract

This article presents data from a field experiment conducted in the south of Uzbekistan, growth, development and fruiting, the cotton yield in one box is much better compared to the control. In this article, the tables give materials for August 1 and September 1, which can be considered more final materials. The yield of raw cotton in the control variant was 31.3 centners/ha, and the yield of cotton after harvesting winter wheat with soybeans for green manure was 35.1 centners/ha, while the maximum yield was 36.8 centners/ha. The yield of cotton after harvesting winter wheat with sowing oats on green manure is 35.3 c/ha. The data obtained indicate that the cotton harvest on the studied variants of short-rotation crop rotation, the formation of bolls of the Bukhara 102 variety occurred more intensively than on the plants of the control variant. The weight of one box in the control was 4.7-5.0 grams, and in the variants where intermediate and green manure crops were the predecessors of cotton, the weight of one box was 5.2-5.5 grams. Regarding the control, in the crop rotation variant, more income was received from the sale of raw cotton and, 600 thousand sums, where it was, formed the maximum yield and the best quality of cotton fiber.
