The yield composition was different among the treatments. The treatment with application of organic manure combined with chemical fertilizer had higher total panicles and filled grains per panicle. The filled grains per panicle in NPKM and M treatments were higher than that of NPK treatment. Application of organic manure was propitious to rice seed formation.
1 000-grain weight had no difference among different treatments. Filled grain rate was higher in the NPKM treatment, to which high photosynthetic rates in late growth period of rice were related, than that of NPK treatment.
