Central Asian Problems of Modern Science and Education


The paper indicates scientifically substantiated continuous, year-round use of irrigated lands in Surkhan-Sherabad valley, southern zone of Uzbekistan. In research, scientifically substantiated production agrotechnology of crops in one agricultural system were investigated, where the crops were grown as a main crop, summer crop and after winter wheat and barley harvesting. The following yields were obtained winter wheat variety “Chillaki” 4.89 to 5.65 t ha-1, barley variety “Bolgali” 5.44 to 6.03 t ha-1, after winter wheat and barley harvesting: maize variety “Uzbekistan-306 AMB” 4.60 to 5.28 t ha-1 grain, variety “Nart” 4.27 to 5.19 t ha-1 grain, cabbage variety “Sharkiya” 44.8 to 53.5 t ha-1, variety “Uzbekistan-133” 45.7 ELECTRONIC JOURNAL OF CENTRAL ASIAN PROBLEMS OF MODERN SCENCE AND EDUCATION. MARCH, 2019-I ISSN 2181-9750 126 to 54.0 t ha-1, upland cotton varieties “Bukhara-6” and “Bukhara-8” 2.85 to 3.21 t ha-1 and 2.89 to 3.24 t ha-1respectively
