Abstract
The article deals with the study of agricultural techniques of cultivation of new varieties of winter wheat under drip irrigation. For the implementation of tasks in 2014 were sown 2 lines of new varieties of winter wheat. Study of the reaction of new winter wheat varieties under drip irrigation showed that super wheatSWW 1/904 and 1/97, having a large size of the photosynthetic organ, dry biologically harvest reached 167,2-172,8 c/ha. Definition at super winter wheat photosynthetic organ in the study was aimed at the formation of a good total biomass. Structural analysis of the ear on the studied samples of super grade wheat SWW 1/904, SWW 1/97 in comparative terms by morphological characters, they were characterized by a certain variety. Research has established in the cultivation of new varieties of winter wheat under drip irrigation, provided the greatest yield grade line of super wheat SWW 1/904. When seeding rate of 4 million. / Ha and the optimal conditions of mineral nutrition with the introduction N120P60 grade grain formed 95.2 centners per 1 hectare.
