PRODUCTION POTENTIAL AND ECONOMIC ANALYSIS OF INDIAN MUSTARD Var. VARDAN UNDER DIFFERENT LEVELS OF NITROGEN AND SULPHUR

A field experiment was carried out with Indian mustard Var. Vardan sown during winter season of 2003-2004 to study the effect of different levels of nitrogen  (0, 60, 80,100,120 and 140 kg/ha) and sulphur (0, 20,40 and 60 kg/ha) on yield and various yield characters as well as the economics of growing mustard. Nitrogen application had significantly increased all the yield contributing characters viz. number of pods/ plants, pod length, number of seeds,seed weight /plant and test weight whereas the sulphur levels had increased significantly only the number of pods/plant and number of seeds / pod. The higher level of nitrogen had significantly increased the grain yield, stick and straw yield, whereas none of them was affected by higher level of sulphur.Neither nitrogen nor sulphur doses affected the harvest index significanty. The maximum net return of Rs 30 940/ha was obtained with fertilizer application of 120 kg N/ha + 20 kg S/ha which gave the cost benefit ratio of  1:2.58 against net return of  only  Rs 9340 /ha with 1:1.02 cost benefit  ratio under control.
