The nitrogen and phosphorus fertilizer with a N/P ratio of 1.50 (60 kg N, 40 kg P2O5 and 30 kg K2O ha-1) produced higher seed and oil yield (1957 kg ha-1 and 775 kg ha-1, respectively) as compared to the recommended N/P ratio of 0.75 with 60 kg N, 80 kg P2O5 and 30 kg K2O ha-1 fertilizer level (1753 kg ha-1 and 690 kg ha-1) and N/P ratio of 0.00 (1581 kg ha-1 and 560 kg ha-1). Further increase in N/P ratio there was no significant increase in the seed yield and oil yield. Economic analyses based on net monetary returns and benefit : cost (B:C) revealed that the treatment N/P ratio of 1.50 with 60 kg N, 40 kg P2O5 and 30 kg K2O ha-1 fertilizer level was most economical with a net monetary returns of Rs. 30,529 ha-1 and B:C ratio of 2.86.
