The object of the research work is varieties of soft winter wheat Yaksart, Gozgon, Bunyodkor. The Fankhauser-2115 seed drill is developed in Brazil, and the СЗУ-3,6 grain seed drill. Scientific novelty of the research is as follows: in the conditions of the southern region of the Republic, the terms, norms and methods of sowing, new varieties of wheat on post-grain crops and cotton inter-rows were tested and optimized; development of resource-saving technology with the use of modern grain seeders in comparison with the traditional grain seeder (CЗУ-3,6); in resource-saving technologies, growth, development and wintering of plants of new varieties of winter wheat, crop formation, resistance to lodging; It is established that the grain of new varieties of wheat by biochemical composition, protein and gluten content, baking qualities meets the requirements of strong and valuable wheat; introduction of production the most optimal technology of cultivation for new varieties of winter wheat. Implementation of the research results. On the basis of conducted research on improving resource-saving technologies for winter wheat cultivation in the southern region of Uzbekistan: on the basis of the conducted research recommendations «Application of resource-saving technology of production of grain crops» (approved on January 25, 2018 by the Ministry of Agriculture and Water Resources of the Republic of Uzbekistan) This technology is introduced in the farm, as a result, the profitability was 45-70 percent; in the farms specializing in the production of grain crops of the Nishan, Karshi and Kasbin districts of the Kashkadarya region, a technology of growing winter wheat in the inter-row cotton was introduced on a total area of 59 hectares using the resource-saving seeder Funkhauser-2115 (Certificate of the Ministry of Agriculture and Water Resources of the Republic of Uzbekistan No.02/21-543 of 16 October 2017). As a result of the application of this technology, the yield of cereals was increased by 5-7 centners per hectare, the wintering of plants, the formation of the crop, the chemical composition of the grain, the protein and gluten content, baking qualities improved; resource-saving agrotechnologies of terms and norms of sowing of winter wheat are widely used in the grain economy in the southern region of the republic Certificate of the Ministry of Agriculture and Water Resources of the Republic of Uzbekistan No.02/21-543 of 16 October 2017). As a result, to save fuel and lubricants, water and other resources, and also received from each hectare a net income of 658-1301 thousand soums and established an increase in profitability to 31-71%. Structure and volume of the dissertation. The dissertation consists of introduction, four chapters, list of used literature and appendixes. The volume of the thesis is 120 pages. 41 ЭЪЛОН ҚИЛИНГАН ИШЛАР РЎЙХАТИ СПИСОК ОПУБЛИКОВАННЫХ РАБОТ LIST OF PUBLISHED WORKS I бўлим (I часть; I part) 1. Аманов О.А., Узақов Ғ.О., Абдуазимов А.М.
