The effectiveness of the biological preparation "Ivan Ovsinsky-fulvohumate" on the cotton variety "Bukhara-6" in the conditions of irrigated meadow-alluvial soils of the Bukhara region

Abstract

Growing high quality crops in the country depends on the fertility of the soil, the amount of humus in it and beneficial microflora. In recent years, Fusarium wilt disease caused by the soil fungus Fusarium (Fusarium oxysporum) has been observed in some crop growing areas to manifest as a "flat" disease. Fusarium wilt has been known abroad and in Uzbekistan for many years. Fusarium wilt has been associated with 1-2 % damage to fine-grained cotton varieties (Gossypium barbadense) in previous years, but medium-fiber cotton varieties (Gossypium hirsutum) have also become affected in recent decades.
