IMPROVED TECHNOLOGY FOR CULTIVATING A NEW VARIETY OF
The productivity of a new variety of winter hard wheat Krupinka under conditions of irrigation of the Tersko-Sulak subprovince of Dagestan was studied. The purpose of the research was to obtain experimental data for the development of a resource-saving technology for the cultivation of a new high-yielding variety of winter hard wheat Krupinka based on the determination of effective doses of mineral fertilizers and the timing of their introduction against the background of various meadow chestnut soil processing systems. Average for 2014-2017 years. the productivity of the Krupinka variety when processing the soil according to the system of the irrigated semipara decreased in comparison with the semi-steam system, respectively by 6.5; 6.9 and 9.5% and was: when applying mineral fertilizers in a dose of N90P50 - 4.44 t / ha; N180P100 - 5.83 t / ha and at the control of 2.88 t / ha, and with a semi-steam system of tillage it was higher and equaled, respectively - 4.73; 6.23 and 3.10 t / ha.
