The comparison of differences is conducted to the average value of single factor effect and the interaction of double factor in the same column in the average of two year since no difference was found in two year results. The same letter after each data means that the difference is not significant, otherwise the difference is significant. Lower case letters represent significant level at < 5% and upper case letters represent significant level at < 1% , EP: effective panicles; GN: grain number per panicle; TGW: 1000-grain weight; SSP: seed setting percentage; MTY: theoretical yields of the main crop; RTY: theoretical yields of the ratoon rice; TTY: total theoretical yield; MPH: Plant height of the main crop; RPH: Plant height of ratooning rice; MHI: Harvest index of the main crop; RHI: Harvest index of ratooning rice; MGD: growth duration of the main crop; RGD: growth duration of ratooning rice; NFPP: Nitrogen fertilizer partial productivity; NAUE: nitrogen absorption and utilization efficiency; PENU: Physiological efficiency of nitrogen use; NAUE: Nitrogen agronomic use efficiency; NCRF: Nitrogen contribution rate of fertilizer.
