To analyze the compensatory growth and yield observed in rice plants adjacent to empty hills and to evaluate the limit of the distance between planted and empty hills allowing safe and effective replanting of young seedlings, field experiments were c

We investigated the changes of water-and soil temperature, redoxy potentials in paddy fields, as well as the changes of roots of rice plants, in relevance among them, in order to know the agronomical capability of different season cultivation of rice

In order to know the agronomical capability of rice plants in different season cultivation, such as early, usual and late, we investigated their growing progress and changes of chemical composition of them. 1) Rice plants cultivated early were lower

For the purpose to know beforehand the heading date of "early transplanted rice", we investigated the relations among the sowing date, the transplanting date, the heading date and the accumulated air temperature from 1956 to 1961. Thus we found high

Four series of experiments were conducted by; (1) removing the rachis branches of "early transplanted rice" just after heading in order to equalize the number of spikelets per unit area with that of "usual transplanted rice"; (2) equalizing the numbe

1. The heavily fertilized rice plant is easier to lodge by breaking of culm than the plant applied with usual dose of fertilizers. The former plant is different from the latter in size and character as follows ; the plant is high, the weight of plant

The process of the elongation and the change of dry weight of certain parts or organs, such as leaf-blades, leaf-sheaths, internodes and panicles were studied. The increase curves of the length and the dry weight of organs showed S shapes (Fig. 1 and
