Effect of silicon fertilization on yield attributing factors, yield and economics of rice cultivation

Abstract

A Field experiment was conducted at a farmer’s field in Kerala during Kharif 2016 to study the effect of various silicon sources on yield attributing factors, yield and economics of rice cultivation. Experiment was laid out in randomised block design replicated thrice with different sources of silicon as soil and foliar application. Rice variety Uma was used as the test crop. Silicon nutrition enhanced yield and yield attributing factors of rice grown in iron toxic laterite soils of Kerala. 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 most of the yield attributing factors, yield and economics of rice cultivation.
