Abstract: Farmer in Ponsai district, Roi Et province has initiated leaf cutting method for improving productivity of broadcasting rice and has practiced this method for years. Farmer claimed that by practicing this method rice grain yield has been improved substantially. In 2004/2005 cropping season, an average rice grain yield of approximately 6.25 ton/ha was obtained. For clarification and verification, the Ubon Ratchathani Rice Research Center has been carrying out 2 on-farm farmer participatory activities in 2006/2007 cropping season. The first activity was carried out at Ponsai district, Roi Et province aiming to study and verify the leaf cutting method in details with farmer who initiated the method. The second activity was carried out in 6 farmer fields in the area of At Samart district, Roi Et province and Muang district, Ubon Ratchathani province aiming to verify the methods with farmers who had never ever practiced this method before. The preliminary results from on-farm trial at Ponsai district, Roi Et province trial at showed that, by practicing this method, rice grain yield of 1.44-2.36 ton/ha were obtained which well below the 6.25 ton/ha that has been claimed before. This trial, however, will be repeated for 1-2 cropping seasons to verify the result. Meanwhile, on-farm trials at At Samart district, Roi Et province and Muang district, Ubon Ratchathani province showed that by practicing this method, on average, rice grain yield was improved by 12 percent and reflection from farmer on leaf cutting method are highly positive.
