In the previous papers, plant factors constituting dry matter production had been investigated analytically. Then the authors compare the productivity applying mathematical model among three varieties of corn possessing different plant forms and different patterns of leaf photosynthetic reaction for light. That is, Golden Cross Bantam has a horizontal plant form and high leaf photosynthetic capacity under abundant radiation. While, Koh No. 7 has rather a vertical plant form and higher efficiency for light utilyzation under low level of radiation. Koh No. 3 is in-between type. Applied values of photosynthetic parameters were quoted the values for imitated population by pots in the previous experiment. Following results were confirmed mathematically among these varieties. 1. Surplus production calculated with Monsi-Saeki model agreed fairly well with the observed CGR acquired in the previous experiment. 2. Golden Gross Bantam is advantageous during initial vegetative stage having only sparse leaf layers. However, the surplus production in Koh No. 7 exceeds those of the other varieties in active vegetative stage. These facts agree with results obtained in the analysis of dry matter production.
