Estimates using the Cobb-Douglas production function indicate that aside from irrigation; land tenure, type of farming and farm size had no significant effect in improving the technological efficiency in both dry and wet seasons. The significant effect of irrigation in improving the productivity of resource-use was attributed to the adequacy of water supply for irrigation in both seasons. In the lowland farms, farmers were not allocating the resource inputs efficiently particularly nitrogen applied, land cultivated and human labor employed. Farm income in the lowland rice farms can still be increased by adjusting the level of inputs used. Addition of nitrogen applied and reduction of the current labor employed appear to be some of the adjustment possibilities.
