Irrigation Procedure And The Effect Of Mineral Fertilizer Norms On Autumn Rye Grain Yield

Abstract

In the conditions of light gray soils of Andijan region studied the norms of mineral fertilizers and the requirements for irrigation procedures in the cultivation of high-quality grain from autumn rye. The obtained data show that pre-irrigation soil moisture is irrigated at 70–70–60% relative to the ChDNS, and mineral fertilizers are applied. N₁₅₀P₇₅K₁₂₀ and N₂₀₀P₁₀₀K₁₆₀ When applying the norms of kg / ha, in addition to the control option 6.7–10.5 ts / ha, pre-irrigation soil moisture is irrigated at 70–80–70% relative to the ChDNS, mineral fertilizers N₁₅₀P₇₅K₁₂₀ ва N₂₀₀P₁₀₀K₁₆₀ When applying the norms of kg / ha, an additional grain yield of 8.0–12.2 ts / ha was obtained compared to the control variant.
