AVAILABILITY OF SILICON, YIELD AND UPTAKE BY RICE AS IN- FLUENCED BY SILICATE MATERIALS WITH FYM IN MADUKKUR SOIL SERIES

Abstract

                                Field experiment conducted to study the effect of various silicate materials with or without FYM on availability of Si, yield, Si content and uptake by rice in Madukkur soil series revealed that addition of FYM at 25 t/ha and silicate materials at 1.0 t/ha increased available Si in soil and crop yield. The Si content was higher in straw than in rice grain.

Key words : Availability of silicon, Rice yield, Silicate materials.
