Field studies on the effect of organic and inorganic sources of silicon against yellow stem borer in rice revealed the superiority of calcium silicate at 2t/ha and diatomaceous earth at 0.45t/ha in arresting stem borer damage with a record of average 5.84 – 11.97 % dead heart (DH) and 2.56 – 8.84% white ear head (WEH) as against 14.75 – 21.34 % DH and 8.35-14.93% WEH in control. At vegetative and heading stages both the treatments resulted in up to 60% and 69% decline in borer damage. The cumulative accumulation of silicon in rice plant was 8.39 and 10.25 % respectively as against 4.15% in control. Higher grain yield (33.64 – 34.99 q/ha) was recorded from plots receiving above treatments as compared to 24.24 q/ha in untreated check.
