Rate of nitrogen and sulphur fertilizers on yield, yield components and seed quality of oilseed rape (Brassica napus L.)

Two experiments were carried out to investigate the influences of nitrogen and sulphur fertilizers on the morphology, reproductive structures and seed quality of new cultivars of oilseed rape (Brassica napus). Yield and yield component responses were not consistent between years and cultivars. For the crop sown in 1988, application of nitrogen at 240 kg/ha increased total dry matter production and combine seed yield. Seed yield increased mainly...
