Abstract:
A field experiment was conducted at the Agronomy field of Sher-e-Bangla
Agricultural University, Sher-e-Bangla Nagar, Dhaka during the period from
March 2014 to May 2014 to study efficacy of different weed control methods
on growth and yield of BARI mungbean 6. There were eight treatments viz.

= weedy check (control), T

= two hand weeding at 15 and 25 DAS, T
=
Quizalofop-p-ethyl 5 EC @ 600 ml /ha at 15 and 25 DAS, T

= Quizalofop-p-ethyl
5 EC @ 700 ml /ha at 15 DAS and one hand weeding at 25 DAS. The highest
weed population was recorded at 25 DAS (526) and 35 DAS (878) with control
treatment. The tallest plant at harvest (35.98 cm), maximum weeds control
efficiency (WCE) at 25 DAS (87.94 %), 35 DAS (93.91 %); number of pod

(80.33), longest pod (9.52 cm ), highest yield (1.53 t/ha) were obtained
from (T
) hand weeding at 15 and 25 DAS. So, two hand weeding at 15 and 25
DAS is the best treatment followed by Quizalofop-p-ethyl 5 EC @ 650 ml /ha
15 DAS + hand weeding at 25 DAS.
