| Abstract: | A simple randomized field experiment was conducted to assess the growth and yield of rape-seed-mustard in relation to sulphur and nitrogen interaction. Three levels of sulphur (0, 40 and 60 kg ha?1) in combination with three levels of nitrogen (60, 100 and 150 kg ha?1) were tested as treatments, T1, T2, T3, T4, and T5. Results indicated significant favourable effects of sulphur and nitrogen, when applied together, on yield components, seed and oil yield. Maximum response was observed with treatment T3 (having S and N of 40 and 100 kg ha1, respectively). Percentage oil content of seed was maximal at T4 (having S and N of 60 and 100 kg ha1) in both cultivars. The increase in N dose from 100 to 150 kg ha?1 without any change in applied S, i.e. 60 kg ha1 (T5), decreased the percentage oil content. The seed and oil yield, however, were similar to T3. Favourable responses of S and N interaction on leaf area index, rate of photosynthesis and biomass production were also observed. |
