Abstract

This article describes the influence of the forms and rates of phosphorus fertilizers on the corn yield in the unwashed and washed off typical gray soils of the Zerafshan Valley. Studies have shown that when cultivating corn for grain, on non-washed-out soils, the optimal rate of fertilizers N240P120K100 was determined with a grain yield of 6.82 t/ha, for washed away - N240P150K100 and a grain yield of 5.81 t/ha.
