Effect of various silicon sources on growth attributes of rice at various growth stages in iron toxic laterite soils of Kerala


Author(s): Guntamukkala Babu Rao and Poornima Yadav PI

Abstract: An experiment was carried out at the farmer’s field in Kerala during Kharif, 2016 to evaluate different silicon sources on growth attributes of rice at various growth stages. Field was laid out in randomised block design with seven treatments and replicated three times. Different silicon sources viz., potassium silicate, fine silica, rock dust, rice husk ash were involved in the treatments and fertilizer application was done according to the recommended dose of fertilizers as per Kerala Agricultural University, Package of Practice. Silicon nutrition have shown significant influence on number of tillers plant-1 at all the growth stages and also on the plant height except at the maximum tillering stage. Among the treatments, fine silica @ 50 kg ha-1 + rice husk ash @ 250 kg ha-1, has shown the better results with respect to number of tillers plant-1 & plant height.
