Investigations on the rôle of organic matter in plant nutrition. Part XI. Effect of manuring on the growth and intake of silicon by dry and wet cultivated rice

Abstract

1. Periodical observations on rice plants grown under wet as well as dry soil conditions, with and without different organic manures, showed that (a) better growth and yield are obtained under swamp conditions than under "dry" ones, (b) there is a greater intake of minerals particularly silicon in the case of the swamped series over that in "dry" series, and (c) the percentage of silicon in plants grown in the swamped and manured soil is greater than in the others. 2. The significance of these observations in relation to (a) the possible beneficial effects of silicate fertilisation in field practice, and (b) the rôle of silicon in the nutrition of the rice plant have been discussed.
