Efforts for higher crop yields have led to extensive use of chemical fertilizers that may possibly leach out of crop root zone on applieation of water or rainfall. The leaching results in wastage of fertilizer as well as pollution of subsurface water. As tillage plays a vital role in the leaching process, it was planned to investigate the differential response of tillage-nutrient leac1hing. Traces of nitrates over and above the residual ones were located up to 150 cm after first irrigation. Some tillage practices were found better than others in effective management of fertilizer
