Results of the investigation of variability character of nitrogen, phosphorous and potassium content in grain and straw of spring triticale of Lana and Kargo varieties depending on cultivation conditions and crop variety peculiar features realized on sod-podzolic, light podzolic soils in the Republic of Belarus were presented. Research results showed that nitrogen, phosphorous and potassium content in the primary and subsidiary products of spring triticale varied substantially. The highest influence was exercised by the nitrogen nutrition content and crop variety peculiar features. Application of the increased doses of nitrogen fertilizers significantly increased the content of the total nitrogen in grain and straw, the content of potassium in straw as well as exercised the positive influence on phosphorous accumulation in plants. Triticale sowing rates did not exercise significant influence on plant chemical composition. It was shown that Lana triticale variety was characterized by higher nitrogen, protein and phosphorous content in grain and potassium content in straw in comparison with the same analysed indices of Kargo variety
