Studies on the Growth of Rice Plants Cultivated in Different Seasons. : I. Growing progress and changes of chemical composition in rice plant

Autor: Kaichiro Suzuki, Masayoshi Uda, Katsuo Sugimoto, Keichi Samoto

Publikováno v: Japanese Journal of Crop Science. 27:333-336

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

Publikováno v: Japanese Journal of Crop Science. 30:338-341

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

Studies on the Growth of Rice Plants Cultivated in Different Seasons. : III. Growing phase and influences of climate and other factors on higher yield in early transplanted rice

Autor: Isamu Yamakawa, Keichi Sumoto, Masayoshi Uda, Kaichiro Suzuki, Katsuo Sugimoto

Publikováno v: Japanese Journal of Crop Science. 29:17-18

1) Changes of the growing phase, chemical components and the root development in early transplanted rice showed similar tendencies to those in the plant of "early-season-culture". (I, II). 2) The grain yield by early transplanting culture was proved
