Abstract:
An experiment was carried out at the central farm of Sher-e-Bangla
Agricultural University, Dhaka during the period from March to June, 2017 to
enhance the yield of blackgram by applying different herbicides. Three
blackgram varieties viz. V
1
(BARI mash-1), V
2
(BARI mash-2) and V
3
(BARI
mash-3) and four herbicides viz. T
1
= Hammer 24 EC (Carfentrazone Ethyl) at
2 ml liter
-1
, T
2
= Gramaxon (Paraquate Dichloride) at 3 ml liter
= Panida
(Pendimethalin) at 4 ml liter
-1
and T
4
= Whip super (Fenoxaprop-p-Ethyl) at 1.5
ml liter
-1
were tested for the study. The experiment was laid out in a
Randomized Complete Block Design with three replications. The effect of
variety, herbicides and their interactions were significant on most of the
parameter measured. In the study the combined effect of V
3
T
4
was found to be
significant in list of the highest number of pods plant
-1
(16.30), number of
seeds pod
-1
(6.64), pod length (4.26 cm) and grain yield (1434.40 kg ha
).
Whereas, the lowest number of pods plant
-1
-1
, T
3
(3.90), number of seeds pod
(5.57) and grain yield (886.60 kg ha
-1
) were recorded from the treatment
combination of V
1
T
3
.
