Abstract
Silicon considered as a beneficial elements for rice production. In order to study of effect of silicon on some growth characters and yield of rice, a pot experiment was conducted in 2010 in the pot house of the Anand Agricultural University Anand, Gujarat (India). Treatments were arranged in a factorial completely randomized design with silicon factor at four levels (0, 100, 200 and 300 ppm) with three replicates. Indian improved and high yielding variety, Gurjari, was used. The results of experiment showed that silicon fertilizers significantly increased plant height, tillers number, 1000-grain weight and yield. The Si application up to 200 mg kg-1 soil significantly increased grain and straw yields of rice over control under low (< 25 mg Si kg-1 soil) and medium (25 - 50 mg Si kg-1 soil) category soils, while it was up to 100 mg Si kg-1 soil in high category soils. Silicon application significantly increased Si concentration and uptake in rice plants grown at all nine soils.
