Abstract:
The experiment was conducted in the research field of Sher-e-Bangla Agricultural University
farm, Sher-e-Bangla Nagar, Dhaka-1207, Bangladesh during the period from November,
2013 to February, 2014 to evaluate the effect of intercropping on the incidence of mustard
aphid. The experiment consists of six treatments such as Mustard with coriander, Mustard
with fenugreek, Mustard with radhuni, Mustard with black cumin, Mustard with wheat and
control (Mustard sole). It was laid out in Randomized Complete Block Design (RCBD) with
three replications. Sole cropping of mustard was grown to compare the effectiveness of other
intercropping treatments. The lowest number of infested plant per plot (17.82), flower
infestation per plant (17.72%), total branch per infested plant (4.39), siliqua infestation per
plant (65.13%) were recorded in mustard with coriander intercropping treatment. On the
contrary, the highest number 33.96, 32.78%, 5.46, 98.08% respectively were recorded in
control treatment. The maximum number of total siliqua per infested branch (25.73), total
seed per infested siliqua (23.20), total seed weight per infested plant (8.86g) and total yield
(0.49 tlha) were recorded in mustard with coriander intercropping treatment and the lowest
result 17.83, 15.97, 4.67g, 0.19 t/ha respectively were recorded in control treatment. Among
the intercropping combinations, mustard with coriander was the most effective treatment for
the management of mustard aphid as well as producing the highest yield
