EFFECT OF SULFUR FERTILIZATION ON RAPESEED-MUSTARD AND GROUNDNUT

Rapeseed-mustard and groundnut, two oilseed species, were compared for their sulfur status at various levels of sulfur nutrition. Rapeseed-m ustard contained a higher amount of sulfur per unit dry matter during vegetative and reproductive stages. This may be attributed to the pres ence of sulfur-rich glucosinolates which are characteristic for crucif ers. Sulfur fertilization enhanced the yield, total sulfur content and protein-cysteine content of seeds in both species. Sulfur fertilizati on did not affect the oil content of the seeds.
