At present, a number of scientific studies have been carried out in the field of grain growing, and the average yield in the Republic of Uzbekistan has reached 55 c / ha. The density of seedlings obtained after sowing is of particular importance for increasing yields, which largely depends on the norms, timing and methods of fertilization. In studies, various options for fertilizer rates were applied at a depth of 35-40 cm before sowing grain, and the use of fertilizers in more surface soil layers, where plant roots are more common, has been little studied. In this study, the effect of the result of using phosphorus, potash fertilizers completely, and nitrogen fertilizers 30% before planting at different planting depths on the field germination of winter wheat seeds was studied, and positive results were obtained.
