The inherent potentiality for grain yield in the Chengai, Twalang and Hutan soil series can be related to the clay content and C.E.C. of the soil. These characteristics also seem to relate to the inherent available nitrogen content of the soil and the response to applied nitrogen fertilizer. In Chengai soil series the higher clay content and C.E.C. could cause a better retention and utilization of nitrogen by the rice plant for a higher grain yield in comparison to Tualang and Hutan series. It was observed that generally a higher nitrogen use efficiency was obtained at the lower levels of nitrogen and in the poorer soils.
