Abstract: The present study was carried out during 1989-1990 to investigate the relationship between the canopy apparent photosynthesis(CAP) rate and grainyield of two high-yielding summer corn cultivars at five different sowing densities. The results are as follows. The CAP rate of summer corn showed a

Key words: Summer corn, Canopy apparent photosynthesis rate, Grain yield.
