THE IMPORTANCE OF APPLICATION OF RESOURCE-SUCCESSFUL AGROTECHNOLOGIES OF SOIL TREATMENT IN THE CULTIVATION OF COTTON AND IN THE SET COTTON OF CROPS

In this paper, it was given data about the experiments carried out in the "winter wheat-mung bean-cotton" crop rotation system in the conditions of the old irrigated typical sierozem soils in Tashkent region, and the soil tillage (0-30 cm) and tillage in comparison with the usual tillage technology compaction was observed in the lower (30–50 cm) layers, efficient use of winter wheat fields can improve soil water permeability by reducing the number of repeated plantings and the number of tractors entering the field due to minimal tillage compared to conventional technology, irrespective of the amount of plant residues (25, 50, 100% plant residues left), the yield of mung bean was 11-12 c / ha under normal tillage, and 10-11 c / ha in the variant with annual tillage, in both normal and intermittent plowing, the highest cotton yield was obtained when 100% of crop residues were left, and in the case of normal plowing, 3.8 c / ha more cotton was obtained than in the case of annual plowing, efficient use of all plant residues left on the surface after the winter wheat harvest, improvement of resource-saving technology in storage and increase of humus content in the soil by placing them underground as much as possible, conducting research on new methods and aggregate selection to prevent soil compaction important.
