The variation in photosynthetic efficiency per unit leaf area (PE) under different levels of light N rates was studied in 10 photosensitive tall and some semi-dwarf rice varieties. Among the cultivars, 'NC. 1281', a tall indica, consistently showed high PE under water-logged soil. Low light (30% normal) and high N application (80 kg/ha) in some varieties significantly reduced PE. Translocation of 14C assimilates to the ear was more in semi-dwarf than in tall types.
