Analysis of agricultural and economic efficiency and doses and terms of mineral and organic fertilizers application during cultivation of cereal winter crops (winter wheat (Triticum aestivum) of Kubus variety; winter triticale of Voltario variety; and winter rye (Secale cereale) of Zarnitsa variety) on sod-podzolic light loamy soils in the conditions of the Republic of Belarus was presented. In the realized study the full organic and mineral fertilizer system with application of N60+30P60K120 and 20-60 t/ha of bedding manure provided the productivity of winter wheat grain of 4,60- 6,19 t/ha, winter triticale - 5,99-7,27 t/ha, and winter rye – 5,33-6,74 t/ha. Cost effectiveness of fertilizer application after sales of winter wheat grain for food purposes was 111,3-142,0%, winter triticale grain – 43,1-59,5 %, winter rye grain – 20,7-34,4%. Yield increasing after application of organic fertilizers was 5,1-21,1 c/ha with cost recovery of 1 tone of manure 25,5-39,2 kg of grain. There was stated the substantial yield increase after the increased doses of organic fertilizers - 50 t/ha. Cost recovery of 1 kg of NPK was 8,1-9,6 kg of grain with yield increasing of 21,8-25,8 c/ha
