Abstract

A pot experiment was laid out at Bangladesh Institute of Nuclear Agriculture, Mymensingh, Bangladesh during January to May, 2012 to investigate the effect of different levels of silicon application on rice growth, yield contributing characters and grain yield of BINA Dhan-8. Silicon was applied through CaSiO3 viz. 0, 5, 7.5, 10, 12.5 and 15 g per pot. This study was carried out in Completely Randomized Design (CRD) with three replications. It was found that silicon (Si) supply levels significantly increased the number of panicles, number of filled grains/panicle, 1000-grain weight and grain yields per pot. The maximum grain yield 46.50 g/pot obtained from 10 g per pot Si application level. In fine it was observed that judicious supply of silicon significantly influence growth, chlorophyll content and yield potentials of rice.
