Impact of organic and inorganic source of silicon in imparting resistance against brown plant hopper Nilaparvata lugens (Stal.) in rice ecosystem

Subhalaxmi Roy and Santosh Kumar Panda

A field experiment was conducted during Rabi 2016 and 2017 in the Central Research Farm of Odisha University of Agriculture and Technology, Bhubaneswar, to evaluate the efficacy of different sources of organic (DAE and RHA)and inorganic form (Casio3) of silicon at different doses were tested on rice cv., TN1 against brown plant hopper in rice. A population build up to the tune of 15.59, 16.42 and 15.65 hoppers /hill have been registered by highest dose of DAE, CaSiO3 and RHA respectively at the peak activity of hopper as against 57.27 hoppers/hill in control, exhibiting their supremacy in arresting the pest. However, the performance was at par with that of medium doses indicating the importance of these silicate fertilizers at moderate doses and the application of this compound in the rice ecosystem can be an eco-holistic approach for effective integration into the pest management system.
