Scientific basis of appropriate sowing of wheat varieties on irrigated land of Uzbekistan

Abstract

In the irrigated lands of Tashkent province, regionalized wheat varieties are usually planted at a rate of 250 kg/ha, but it would be possible to increase yields and grain quality if a scientifically based optimal sowing rate was recommended for each variety. Another opportunity to increase wheat yields in the region is the development of seed production. Numerous studies and practices have shown that it is possible to increase wheat yields by 20-25 by sowing wheat seeds. In this regard, the most pressing issue is to increase the level of seed germination. In this article, it is important to study the scientifically based sowing norms, physiological maturation of seeds, and their impact on yield and grain quality in order to take full advantage of the potential of regionalized varieties of wheat in irrigated lands. The determination of the most optimal planting norms, taking into account their biological properties, is based on research.
