Abstract

An experiment was conducted during the kharif seasons of 2018 and 2019
with varieties viz., RT 346, RT 351, TKG 306, TKG 308, Rama, VRI 1, GT 10 and TKG
22 of sesame (Sesamum indicum L.) to assess the avoidable loss in seed yield due to leaf
webber and capsule borer under rainfed conditions at ARS, Mandor. The performance
of all the promising sesame varieties grown under protected conditions were found
significantly superior over the unprotected conditions, except in case of two varieties
viz., TKG-308 and VRI-1 at capsule stage only. The varieties viz., RT 351, TKG 308
and GT 10 were found significantly superior over all other varieties of sesame grown
under both the protected and unprotected conditions. Avoidable loss recorded ranged
from 25.51 to 61.45% in different varieties under protected condition in comparison to
unprotected conditions, maximum in RT 351 and minimum in VRI 1 due to leaf webber
and capsule borer. The pest caused significant loss in seed yield under unprotected
condition in comparison to protected condition. The varieties viz., TKG 308, RT 351 and
GT 10 performed good under unprotected conditions and gave highest seed yield, the
variety GT 10 stands first in respect to record lowest damage (9.58%, 15.89% and 5.40%
at vegetative, flowering and capsule stage, respectively) under unprotected conditions.
Varieties viz., RT 351, TKG 308 and GT 10 gave highest seed yields of 444 kg ha-1, 433
kg ha-1 and 397 kg ha-1, respectively, under protected condition. Overall, all the varieties
performed well in protected conditions and their yield potential were also increased.
