Abstract
It was achieved to improve agro physical properties of soil by forming of 22.41-52.92 t/ha green biomass of pea, chickpea, rape and barley when sown as green manure as well as tilling it into soil in summer July 10 wheat freed areas, and autumn October 10 cotton freed areas. It was determined that the mass of soil before the first irrigation of cotton in 0-20 cm tilling layer of soil with green manure applied variant was 0.06-0.08 g/cm 3 ; 0.03-0.08 g/cm 3 and it was less 0.05-0.07 g/cm 3 ; 0.03-0.08 g/cm 3 in 20-40 cm of soil layer relatively to control-without green manure variants. In its turn, it creates best and favorable condition of branching root system of cotton-plant and will be achieved to get high and quality yield.
