An experiment was conducted to investigate the response of rapeseed to nitrogen and sulphur at the Research Farm ofthe College of Agriculture, Central Agricultural University, Imphal during raM seasons of 1990-2000 and 2000-2001 on a clayey soil. Treatments consisted of three levels of nitrogen (0, 40 and 60 kg ha-I) and three levels of sulphur through gypsum (0, 20, 40 kg ha-I). Application of 60 kg N ha-I produced the highest seed (1.18 t ha-I) and straw (1.69 t ha-I) yield of rapeseed. Oil content in seed increased significantly with the addition of nitrogen (60 kg ha-I) and sulphur (40 kg ha-I). Total N uptake by rapeseed progressively increased from 39.6 to 72.6 kg ha-I with the increase in N levels. The uptake of sulphur increased with sulphur application up to 40 kg S ha-I. Uptake of P and K by rapeseed increased with graded levels of-nitrogen and sulphur. .
