Zero tillage saves tillage and irrigation costs, results in yield gains through a possible improvement in sowing time and enhanced fertilizer and water use efficiencies. The present study was conducted to explore the possibilities of saving critical inputs and to enhance the profit margin of the rural farmers of Uttar Dinajpur, Dakshin Dinajpur, Malda and Murshidabad districts of West Bengal through National Agricultural Innovation Project. Mean grain yield of 10 villages showed that zero tillage practices produced 8.004% more grain yield than conventional tillage method. On an average zero tillage method save total cost of Rs. 4449.67 ha -1 and increase profit margin of Rs. 7056.25 ha -1. Zero till field also recorded higher B:C ratio of 0.923 as compared to conventional tillage method (0.432).
