Burning of rice stubbles is widely practised in Punjab, India, due to a lack ofsuitable machinery to direct drill wheat into combine-harvested rice residues.Although burning is a rapid and cheap option, and allows quick turn around betweencrops, it has serious effects on human and animal health due to air pollution,reduced soil fertility due to loss of nutrients and organic matter, and green house gas(GHG) emissions. The recently developed Happy Seeder (HS) overcomes thetechnical problems associated with direct drilling into rice residues. The primaryaim of the present study was to conduct a preliminary evaluation of the directfinancial benefits and costs to farmers of use of the HS in comparison with thecurrent practices of straw burning followed by direct drilling or conventional tillageprior to sowing. The results of the evaluation suggest that the HS technology ismore profitable than conventional cultivation or direct drilling after burning, andthat it is viable for farmers from a financial perspective. The net present value(NPV) of the benefits is highly sensitive to yield; a 5% increase in yield with the HSdoubles the increase in NPV of the HS over conventional tillage. The NPV is alsoquite sensitive to changes in herbicide use, and less sensitive to changes in irrigationwater saving and discount rate. Furthermore, there are significant economic,community and environmental benefits through adoption of the technology. Forwidespread adoption of the technology, a range of potential mechanical, technical,social, institutional and policy constraints need to be considered and addressed inconjunction with a detailed economic assessment of the HS technology.
