Abstract

Nitrogen has long been recognized as one of main factors which give remarkable influence upon the growth and yield of rice plants. In order to obtain some information on the response to fertilizer in rice-breeding, some experiments were carried out in 1955. 1. The varieties used: were "Eiko" (tillering type) and "Okute-eiko" (panicle type). Both were cultured in nutrient solution. In this paper, the effect of nitrogen content upon the several characters of rice plants were reported. 2. The following numerical charcters increased accordirig to shift of nitrogen content from 10 to 320 ppm. in the nutrient solution. These were number and weight of stems, panicles, roots, and grains per plant. This tendency was more distinctly observable in tillering type than in panicle type.
