PRODUCTIVITY OF JOINT APPLICATION OF BENTONIT CLAY, MINERAL FERTILIZERS STANDARDS AND IRRIGATION PROCEDURE IN WINTER WHEAT

Аннотация

The use of bentonite clay in addition to the rate of mineral fertilizers N150P105K75 kg/ha before sowing winter wheat every year in a 1:1 system (cotton-grain) under conditions of typical gray soils of the Tashkent region with irrigation in the order of 60-70-60 and 70-80-70 % of pre-irrigated soil moisture, relative to LFMC, had a positive effect on the agrophysical properties of the soil, on the growth and development of the plant. Relative to the control variant, by the end of the growing season, the actual density of winter wheat increased to 54-59 m2/piece, growth to 4,3-6,8 cm, the number of common stems to 1,0-1,050 million/ha and the number of productive stems to 758,0-774,0 thousand/ha, achieved up to 12,5-13,4 centner of additional grain yield
