The effects of highly concentrated air with CO_2 on the growth, the yield, the yield components and the chemical compositions of rice plants were examined in a field as well as in pots. Some noteworthy results were obtained as follows from an experiment, in which poted rice plants grown in a highly CO_2-concentrated (0.1 %) phyto-torone were compared with those in natural condition. The rice plants treated with high concentration of CO_2 were (1) more numerous in number of tillers and less in plant height, (2) higher in dry weight, in the amount of starch and sugar, in total carbohydrate, in total nitrogen and potassium, (3) mostly more numerous in number of panicles per plant, in number of spikelets per panicle, in percentage of ripened grains, and in consequently, (4) higher in yield and straw weight than those in the natural condition.
