Effect of silicon nutrition on dry matter production at various growth stages of Rice in iron toxic laterite soils of Kerala
Author(s): Guntamukkala Babu Rao and Poornima Yadav PI
Abstract: An experiment was conducted in farmer’s field in Kerala during Kharif 2016, to evaluate different sources of silicon on dry matter production in rice. The experiment was laid out in a randomised block design with three replications and seven treatments using Uma as the test variety. Different silicon sources viz., rock dust, fine silica, rice husk ash and potassium silicate and other cultural practices and fertilizer management were practiced as per Kerala Agricultural University, Package of Practice. Silicon nutrition enhanced dry matter production at various stages in rice except at maximum tillering stage Among the treatments, recommended dose of NPK kg ha-1 + fine silica @ 50 kg ha-1 + rice husk ash @ 250 kg ha-1, has shown the better results with respect to dry matter production in rice.
