Studies on Photosynthesis in Rice Plant : (VII) Photosynthesis of rice plants grown under different condition in manuring or plant spacing

Abstract

In the previous papers, we reported on the relation between light intensity and photosynthetic rate of the whole plant and on the plant factors constituting the field photosynthetic ability of rice-plant communities cultured early, ordinarily or late in the field. In this paper, we are reporting further on the results of transaction with the same problems in the case of plants grown at varying levels manuring or spacing.
