Dunkeld). Sole dose of N proved superior to split dose and produced significantly taller plants. Nitrogen application methods had no influence on grain yield and oil contents. Grain yield increased with increase in P level. Oil contents significantly increased by P up to 50 kg ha-1, but further increase in P decreased the oil contents. Potassium showed no influence on any observation other than oil contents. A combination of 100 kg N, 75 kg P and 30 kg K ha-1 seems to be the optimum dose in terms of higher canola grain production. While highest oil contents can be obtained with 100 kg N, 50 kg P and 60 kg K ha-1.]]>Chen, M.L., X.L. Jaing, B.Y. Wang, B.Y. Zhov, Z.Y. Zheri and G.S.
