Qattiq bug'doyning don hosildorligiga ma'danli o'g'itlar me'yori hamda sug'orish tartiblarining ta'siri

Under the conditions of the ancient irrigated meadow soils of the Andijan region, the requirements of the norms of mineral fertilizers and irrigation regimes for the cultivation of high-quality grain of winter durum wheat were studied. The results show that soil moisture before irrigating winter durum wheat during the growing season is irrigated about 60-70-60% in relation to the NPV 9-18.3-20.3 c/ha, straw yield 10.6-20.3-26.6 c. / ha, pre-irrigation soil moisture is about 70-70-60% relative to the NDN, grain yield 11.1-20.0-22.1 c/ha, straw yield 12.6–23, 3–30.4 q/ha. When analyzing the yield of grain and straw under the conditions of irrigation regimes, the yield of winter durum wheat for the growing season was 70-70-60% of the pre-irrigation soil moisture in relation to the NPV, the pre-irrigation soil moisture was 60-70-60% relative to the NPV 2.1-3.3 -3.8-3.9 c/ha, and straw yield. High results of 3.7-5.7-6.7-7.5 q/ha were established.
