A field experiment was conducted during kharif 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., Swarna against brown plant hopper in rice. A population build up to the tune of 11.59, 17.2 and 23.16 hoppers /hill have been registered by highest dose of DAE, CaSiO3 and RHA respectively at the peak activity of hopper as against 65.59 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 for economic and effective management of BPH in rice.
