The article notes that in the world and our country, non-irrigated fields have long been one of the important sources in meeting the needs of the population for grain crops, that durum wheat is a hot and dry climate crop, and that the demand for the production of durum wheat (Triticum durum), the most important raw material in the pasta and confectionery industry, is increasing Effective use of non-irrigated fields, increasing the yield of grain grown in non-irrigated fields, resistant to unfavorable factors, taking into account the high need for grain of durum wheat (Triticum durum) in the domestic and foreign markets, the creation of new varieties of durum wheat that meet the requirements of the state template, with a high yield and grain quality for non-irrigated fields, as well, taking into account soil and climatic conditions, ensuring the cultivation of a high and high-quality product based on the improvement of their scientifically based cultivation technology is one of the important tasks. Based on this, the goal of our research is to determine and introduce into production the optimal sowing times and norms for the cultivation of a cost-effective and high grain crop from new durum wheat varieties in the conditions of typical meadow soils of the non-irrigated hilly steppe (flat steppe) region of Kashkadarya region. The article presents scientists who have carried out scientific prohibitions on the treatments of selection and cultivation of durum wheat in the Republic and abroad on non-irrigated fields, materials and methods of research, the results of the study show the influence of the timing and norms of planting on the growth, development, grain yield and quality of the new variety "Mingchinor" of durum wheat. According to the results of an average 3 – year study, a new Mingchinor variety of durum wheat was obtained after pure plowing-2.5 million per hectare on October 21. the highest grain yield when sown germinate seed is 18.6 centner per hectare, and with its delay, the sowing standards are 3.0 million per hectare, when increasing the germinate seed, it is indicated that 16.8 centner will be obtained in the period of November 11 and 13.9 centner high grain yield in the period of December 1.
