ABSTRACT
An experiment was conducted at the Agronomy field of Sher-e-Bangla Agricultural
University, Dhaka during October, 2017 to March, 2018 to study on the performance
of different weed management techniques affecting growth and yield of mustard
varieties. The experiment comprised of two factors viz., (i) three mustard varieties
viz., V
1
= BARI Sharisha-14, V
2
= BARI Sharisha-15 and V
= BARI Sharisha-17 and
(ii) Five Weed managements viz., W
0
= No weeding (control), W
3
= One hand weeding
at 10 DAS, W
2
= Two hand weeding at 10 and 20 DAS, W
1
= Panida 33EC
(Pendemethylin) @ 2000 ml ha

at 5 DAS and W

at 21 DAS. Results revealed that mustard varieties, weed
managements techniques and their interaction significantly affected weed population

), biological yield(t ha
) and harvest
index (%) of mustard. Among the mustard varieties ‘BARI Sharisha-17’ performed
superior than other varieties and it produced (1.61 t ha
-1
) seed which was 96.34%
higher than BARI Sharisha-14 (0.82 t ha
-1
). In the case of weed managements two
hand weeding at 10 and 20 DAS (W
) resulted better than other treatments and the
estimated seed yield (1.61 t ha
-1
2
) was recorded which was 69.47 % higher than no
weeding treatment (0.82 t ha
-1
). Similar trend was observed in interaction of variety
and weed managements. BARI Sharisha-17 (V
) along with two hand weeding at 10
and 20 DAS (W
2
3
) produced maximum seed yield (1.89 t ha
-1
) which was 329.55%
higher than BARI Sharisha-14 (V
) along with no weeding treatment. So it might be
concluded that BARI Sharisha-17 along with two hand weeding at 10 and 20 DAS
could be a better mustard cultivation package in cultivating mustard at SAU campus.
