Biomass yield was significantly higher in the mineral fertilizer and rice residue than in the control treatment. Total N uptake by rice was not significantly affected by rice residue incorporation. A lower N uptake in the rice residue plots can be attributed to relatively high C/N ratios. The result suggests that the application of rice residue at a suitable time is crucial for maximizing the beneficial effects of rice residue application. In particular, the increased immobilization process in early stages and the subsequent gradual remineralization allowed plant to utilize N more efficiently. Rice residue application noticeably reduced the pH of the flooded water as compared with mineral fertilizer alone.]]>Ayoub, A.T.,199955117121Bevacqua, R.F. and V.J.
