Paddy and Silicon Application

Abstract

The present study has been conducted to evaluate the effects of Potassium silicate, as a silicon source, on the morphological, biochemical, and yield parameters of the two varieties PB-1121 and Karan bhog -521 of rice (Oryza sativa L.). For this, thre econcentrations of potassium silicate, i.e. 3g, 5g, and 7g were mixed into 10 kg soil along with basal fertilizers and the results were compared with the control.The effects were observed on no. of effective tillers, spikes, spikelets, grains, the weight of grains, etc. Supplementation of silicon has resulted in an increase of 104.85% in no. of tillers per hill, 135.4% in fertile tillers, 16.22% number of grains per panicle, 172.56% number of grains per hill,8.48% in weight of husk per hill, 18.88% in weight of grains per hill in PB- 1121 and 14.09% no. of spikes per panicle, 147.12% in total spikes per hill, 16.64% in no. of spikelets per panicle, 142.36% in total spikelets per hill 116.13% in no of tillers per hill, 114.36% in fertile tillers per hill, 1.25% in weight of grain per hill Karan bhog-521 variety. Silicon fertilizers being non– corrosive and environmentally friendly can become a suitable fertilizer for increasing the yield of paddy crops in the soil of District Rohtak, Haryana.
