Abstract:
The experiment was conducted to evaluate the performance of different varieties and
management practices in controlling bean pod borerof country bean during the period
from April to October, 2014. The experiment consists of the bean varieties as the IPSA
Seem-1, IPSA Seem-2, BARI Seem 7, and insecticides Voliam Flexi 300 SC, Sumi Alfa
5 EC,Neem seed karnel as the treatments. The experiment was laid out in Randomized
Complete Block Design (RCBD) with three replications. The minimum infestation
percentage (11.71 %) and maximum yield (17.61 t/ha) was obtained from BARI Seem 7
while variety and the maximum infestation (14.86 %) and minimum yield (12.90 t/ha)
was obtained from IPSA Seem-1 variety. The minimum infestation (12.24 %) and
maximum yield (15.77 t/ha) was obtained while sprayed Voliam Flexi 300 SC treatment
and the maximum infestation (14.56 %) and minimum yield (14.42 t/ha) was obtained
from the control treatment. In case of combined effect the minimum infestation (9.52 %)
and maximum yield (19.20 t/ha) was obtained from combination of BARI Seem 7 and
Voliam Flexi 300 SCand the maximum infestation (22.02 %) and minimum yield (10.70
t/ha) was obtained from IPSA Seem-1 and control treatment combination. The
relationship between percent pod infestation by number and yield (t/ha) is negatively corelated.
From the study it may be concluded that BARI Seem 7 treated with Voliam
Flexi 300 SC performed the best results
