To determine the optimal nitrogen rate for mechanical transplanted rice(MTR) with straw manuring and to clarify the effects of nitrogen rate on grain yield and the formation of high quality population, the good eating quality rice Naning 9108 was field-grown to investigate the yield and yield components and population quality of MTR with straw manuring in 2013 and 2014. Results showed that, yield of MTR increased and then reduced with increasing nitrogen rate. At a nitrogen rate of 270 kg/hm2, the grain yield of MTR peaked, which is mainly due to high spikelet number of the population. With increasing nitrogen rate, panicle number of MTR increased, spikelet number per panicle increased and then reduced, filled grain percentage and 1000-grain weight followed a declining tendency. The number of stem and tiller, leaf area index, photosynthetic potential, dry matter accumulation increased with increasing nitrogen rate, but dry matter accumulation after heading, percentage of productive tiller, leaf area rate of productive tillers, leaf area rate of flag leaf to 3rd leaf from top of productive tillers and spikelet per leaf area increased and then reduced. Therefore, optimal nitrogen rate improves grain yield of MTR and optimizes population quality.
