Parameters related to photosynthetic nitrogen use efficiency (PNUE) are key contributors to rational dry matter distribution and improvements in the spike weight of rice. However, it is unclear whether the interaction effects of drought–flood abrupt alternation (DFAA) have an antagonistic compensati...
