Abstract
Aphid infestation significantly limits mustard
(Brassica spp.) output in Bangladesh. This research aimed to assess the effects
of varying planting periods and mustard cultivars on aphid infestation at
Sher-e-Bangla Agricultural University, Dhaka. A two-factorial randomized
complete block design was utilized, including three planting dates (9, 16, and
23 November) and eight mustard varieties (Tori-7, BARI Sharisha-6, -9, -11,
-13, -14, -15, and -16). The results indicated a considerable increase in aphid
infection associated with delayed seeding. Early sowing (9 November) yielded
the lowest mean plant infestation (49.41%), whereas late sowing (23 November)
exhibited the greatest (78.48%). BARI Sharisha-13 had the greatest resistance
to aphids, with a mean infestation of 46.45%, whereas Tori-7 demonstrated the
highest susceptibility at 80.71%. The interaction impact between sowing time
and variety was substantial. Early sowing combined with BARI Sharisha-13
resulted in the lowest infestation. These findings suggest that adjusting
sowing time and selecting appropriate varieties can substantially reduce aphid
infestation and improve mustard yield in Bangladesh.
