Investigations carried out under conditions of meadow alluvial soils in the southern zone of the Republic of Karakalpakstan have determined the effectiveness of various norms of mineral fertilizers (N160P100K75; N200P140K100 and N240P170K125 kg / ha) applied to cotton grown in the following year after winter wheat and as a secondary crop of mung beet against mineral fertilizers (N30P80K60 kg/ha). When cotton was grown in the following year after winter wheat and the second crop of mung beans, the highest yield of raw cotton was obtained, which was 3.4 t/ha against the background of mineral nutrition N200P140K100 kg / ha. As a result of research, in the system of crop rotation, winter wheat-recurrent cotton culture is scientifically grounded in the effectiveness of the agro technical method of locating the mung beans culture before sowing cotton.
