Abstract: A field experiment was conducted in kharif season of 2015 to investigate the influence of silicon solublizer on different rice genotypes namely PA-6129, PA-6201, PA-6444, PHB-71, US-312, and BPT-5204. Soil application of silicon solubilizer was given at the time of maximum tillering, panicle initiation and 50% flowering stage. Different biochemical observation like Silicon content (mg g-1) and chlorophyll content (mg g-1) was taken at severel growth stages like maximum tillering, panicle initiation and 50% flowering. It was found that application of silicon solublizers can increased silicon content in rice leaves in many folds which enhanced the defence and protective mechanism from several biotic and abiotic stresses in rice genotypes. Four fold increase in silicon content was found also in genotype BPT-5204 leaves as compared to control at all the three growth stages. Silicon solublizers treated plants shows significance increased in chlorophyll a, chlorophyll b, and total chlorophyll content in rice leaves. The chlorophyll a content was increased by 1.48% in PA-6444 and chlorophyll b was increased by 21.92% in PA-6129, total chlorophyll content was maximum increase (13.81%) in PA-6201 in treated plants when compared with control. Among all the genotypes and treatments the chlorophyll fluorescence (Fv/Fm) of PA-6201 was significantly increased from rest of the genotypes at control and as well as silicon solublizers treatment.
