STUDY OF REGULATORY ACTIVITY OF D. STRAMONIUM WATER EXTRACT IN COTTON CROPS

The effect of the aqueous extract of Datura stramonium on the germination and vigor of germination, on the growth and development, and also on the yield of cotton plants has been studied. The data obtained showed that the aqueous extract improved seed germination by 6.9% and germination energy by 5.5%. The growth of the main stem has increased, the onset of the budding phase, flowering and ripening of bolls has accelerated, the rate of opening of bolls has increased by 5-6 days. Treatment of cotton seeds with an experimental extract contributed to an increase in yield by 1.2 centners / hectare.
