On middle-cultivated sod-podzolic light sandt soils of western part of Belarus spread from depth of 0,7 m by moraine loam a winter wheat "Legend" under optimum conditions of a nitric feed on background Р50K120 and application of means of protection of plants forms productivity of grain of 41,5-47,7 c/ha. The recoupment of nitrogen by fertilizers of grain makes 9,6-9,7 kg. Fractional entering of nitric fertilizers (90-120 kg/ha) on a background of P50K120 without application fungicides provides reception of grain of 38,7-41,5 c/ha with its good quality. The content of fiber and gluten raises with increase in dozes of nitric fertilizers, terms of their entering. Positive action of late top dressing on quality indicators of grain - the content of fiber and gluten is established. Means of protection of plants raise efficiency of applicated nitric fertilizers that provides an increase of a crop of 4,9-6,2 c/ha in relation to variants without their application. Processing of fungicides plants in a flag phase a leaf raised the content of fiber on 0,5-0,8 %, gluten on 1,2-3,2%
