【 摘 要 】

The growth and yield components of the second crop (ratoon crop) are affected by the growth of the first crop. The first crop growth was modified by the deep-flood irrigation (DF: 20 days of 15 cm flooding), reduced fertilizer (RF: reduced by 50%), and without treatment (Control). The number of tillers in the second crop was larger in DF and RF than in the Control. The number of days to heading was in the order of DF
