The results from the trials showed the technical and economic feasibility, as well as the social acceptance of cultivation on soybeans and mungbeans under no-tillage after rice. The main role of No-tillage was to allow the cultivation of a second crop after rice, thus taking advantage of the residual soil moisture. However, the system is not yet completely turned into No-tillage, because rice is still being cultivated under conventional system. It is necessary to know which could be the incentives for the farmers to change the system of rice cultivation.
