Abstract: The field experiment was conducted at Division of Soil Science and Agricultural Chemistry, College of Agriculture, Kolhapur, India, to study the influence of rice husk ash and bagasse ash as a source of silicon on growth, yield and nutrient uptake of rice. The present investigation was carried out in randomized block design. The treatments consist of four levels of silicon (Si) viz. 0, 250, 500 and 750 kg Si ha-1 which was supplied through rice husk ash (RHA) and bagasse ash (BA) and were replicated four times. The plant height (cm), number of tillers hill-1, thousand grains weight and dry matter hill-1 (g) of rice increased significantly due to application of silicon. The application of silicon @ 250 kg ha-1 through bagasse ash was found optimum for increase in the grain yield (49.66 q ha-1) and straw yield (53.84 q ha-1) of rice. The highest benefit-cost ratio (1.52) was recorded with application of silicon @ 250 kg ha-1 through bagasse ash. The silicon uptake of rice increased significantly due to application of silicon either through rice husk ash or bagasse ash at different growth stages. The significantly highest uptake of silicon was recorded with the application of silicon @ 750 kg ha-1 through bagasse ash. The uptake of N, P and K increased significantly with application of silicon. The plant available silicon was enhanced at harvest of rice due to silicon application through rice husk ash and bagasse ash.
