Abstract

In the conditions of typical gray soils of Tashkent region, before sowing of winter wheat under the plow once in three years in addition to the norms of mineral fertilizers N₂₀₀P₁₄₀K₁₀₀ ва N₁₅₀Р₁₀₅K₇₅kg/ha 1,5-3,0-4,5 t per hectare. The effect of irrigation on soil agrophysical properties and plant growth and grain yield was studied for three years in the order of 60–70–60 and 70–80–70% of the soil moisture before irrigation during the period of application, using bentonite mud.

The obtained data show that the pre-irrigation soil moisture is irrigated in the order of 60–70–60% relative to LMFC, in addition to the norms of mineral fertilizers (N₂₀₀P₁₄₀K₁₀₀ ва N₁₅₀Р₁₀₅К₇₅/hec) 1,5–3,0–4,5 t per hectare. Germination of seedlings 18–16 compared to control options when using bentonite silts in the amount of 18–16; 33–28 and 46–44 m²/piece, total number of stems 49,0–81,6; 96,6-99,4; 104,7-108,3 m²/piece, and the number of productive stems is 47,4-76,1; 97,7-100,3; 102,2-107,6 m²/grain was observed, grain yield was 6,9-11,3; 8,8-13,4; It was noted that it was higher than 10,1-14,7 ts/hec.
