The object of research work is the seeds of Atriplex canescens obtained from ICARDA (International Center for Agricultural Research in Arid Zones, Aleppo) and seeds of Atriplex undulata, obtained from ICBA (International Center for Salt Resistant Crops, Dubai). Scientific novelty of research work as follows: for the first time, the growth, development, viability, productivity, liveliness and nutritional properties of Atriplex canescens and A.undulata species, derived from the Arabian soil in the conditions of the Qarnabchol soil-climatic conditions; was created from perennial species of Atriplex undulata the «Yagona» variety; laboratory and field strength of Atriplex canescens and A.undulata seeds, their sharp increase in cold stratification and the seeds' susceptibility; the formation of the root system of plants, the transpiration intensity of the Atriplex undulata plant, the amount of water in the tissues, the water scarcity of the local phytomeliorant (Kochia prostrata (L.) Schrad); agrotechnical measures of cultivation of Atriplex canescens and Atriplex undulata plants in the conditions of Karnabchul were developed (seeding time, norms and depth). Introduction of research results. Based on the results of research on the development of agro-technical measures for the cultivation of long-haul alabuta in the herbaceous grass-barberry conditions: for agricultural cooperatives «Agrotechnical recommendations for the cultivation of perennial Atriplex undulata in the soil-climatic conditions of Garnabchul with Euler-Efemer» (Ministry of Agriculture and Water Resources dated 12.06.2017, reference number 6). As a result, the yield of pastures has been increased to 15-25 ts / hectare per hectare; «Yagona» grade of Atriplex undulata of perennial has been created and submitted to the State Commission for the testing of varieties of agricultural crops (State Reference Testing Commission dated 21.08.2017, 53/4-369). At present, the primary seed areas of this species have been established; In order to increase the productivity of pastures, A.undulata species has been introduced in Samarkand region in 4 hectares, in Jizzakh province - 4 hectares, in Bukhara region - 4 hectares, on a total area of 12 hectares (Ministry of Agriculture and Water Resources dated 27.11.2017, 02/12-613). As a result, pasture yields increased by 4-5 times (35,4 s/ha) relative to natural pastures. The structure and volume of the thesis: The structure of the thesis consists of an introduction, 5 chapters, conclusions, references 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. Раббимов А., Хамроева Г.
