A field experiment was conducted during kharif, 2016 at the farmer's field in Kerala, to evaluate the effect of various sources of silicon on soil pH, OC, EC and soil texture. Experiment was laid out in randomised block design replicated thrice with seven treatments using Uma as the test variety. The treatments comprised of silicon sources viz., fine silica, rock dust, rice husk ash and potassium silicate, along with the recommended dose of fertilizers as per Kerala Agricultural University. Among the treatments, recommended dose of NPK kg/ha+fine silica@50 kg/ha+ rice husk ash@ 250 kg/ha, had shown better results with respect to soil pH and OC.
