The present study was undertaken to compute the economics of using fertilizers and manure under continuous rice-wheat cropping for over 3-decades on an Aquic Hapludoll. Various fertilizer and manurial treatments substantially increased the yields of both crops with successive increase in the levels of NPK along with Zn. Application of 100 % NPK with FYM produced the highest yields as well as maximum net profit (Rs. 32477/- ha-1 yr-1) of nutrient application. Treatments receiving recommended level of optimal NPK with zinc fetched about 97 per cent of the maximum net profit. With the application of only recommended N with Zn and at 50% NPK dose with Zn net profit was only about 77 per cent and 67 per cent, respectively. However, their value cost ratios were higher than all other treatments. These two fertilizer practices seem to be suitable options for low input farming.
