Abstract:	It is shown that, in a nine-course grain-sugar beet crop rotation, a combined tillage system (non-moldboard for cereals and moldboard for row crops)with annual application of 5 tons of manure and N₅₃P₅₆K₅₃ per hectare of rotation area restrains deterioration of the physicochemical properties of chernozem. The yield of all crops in the rotation increases.

Keywords:	grain-sugar beet crop rotation tillage chernozem properties
