Yield wheat yield on erosion and dangerous slope depending on the method of main soil treatment and mineral nutrition level

The article presents the results of 2014-2016 studies of the formation of reserves of productive moisture and 2015-2016 yields of winter wheat varieties Donskaya Lira on the erosion-dangerous slope, depending on the method of the main tillage and the level of mineral nutrition. It was established that the highest indicators of productive moisture reserves, yield - 6.1 t / ha were obtained with chisel basic tillage and application of the second level of mineral fertilizers by the standard N84Р28К46 (per 1 hectare of crop rotational area). A higher payback of 1 kg of fertilizers by increasing the yield was obtained when mineral fertilizers were applied by the zonal norm N42P28K46 and amounted to 11-13 kg / kg depending on the method of the main tillage.
