Biological properties of cotton varieties

Study of biological properties of cotton-plant and their adaption to the natural conditions, especially in the south of Uzbekistan, where optimally selected norms of irrigation increase the efficiency of irrigating techniques, shows the ways of raising fertility of cotton-plant in the fields and recommends optimal elements of irrigation techniques which are considered as the basis of plant cultirating technology, supplying entire, field uniformly with water, neither too much nor too little, since salinization is not restored.
