Abstract:
The experiment was carried out to study the effect of irrigation management on
growth and yield of fodder grasses conducted at the farm of Sher-e-Bangla
Agricultural University, Sher-e-Bangla Nagar, Dhaka-1207 during the period from
October 2020 to January 2021. Four grass varieties viz. V
1
(Napier grass), V
(Para
grass), V
3
(Pakchong grass) and V
(German grass) with four levels of irrigation
including control viz. I
0
4
(control; no irrigation), I
(Irrigation at 20 days of plantation),
I
2
(Irrigation at 20 and 40 days of plantation) and I
1
(Irrigation at 20, 40 and 60 days
of plantation) were considered for the present study. The experiment was laid out in a
Randomized Complete Block Design (RCBD) with three replications. Regarding
varietal performance, V
3
3
(Pakchong grass) performed best in terms of growth, yield
and yield contributing parameters followed by V
1
(Napier grass) but the variety V
(Para grass) gave the highest protein content compared to other varieties. In terms of
irrigation effect considering growth, yield and yield contributing parameters and
quality parameters I
(Irrigation at 20, 40 and 60 days of plantation) showed the best
performance in comparison to other irrigation treatments including control. In case of
the treatment combination of variety and irrigation, the highest plant height (90.47
cm), number of leaves plant

(45.10), number of branches plant

(18.73), internode
length (11.97 cm), number of internodes tiller

(10.77), fresh weight plant
(436.10
g), dry weight plant
-1
(54.73 g), fresh weight plot
-1
(5.23 kg) and fresh yield ha
(9.69
t) were achieved from V
3
I
3
whereas control irrigation I
(no irrigation) gave the lowest
results on respected parameters. Regarding quality parameter, the highest protein
content (12.93%) was recorded from V
2
I
3
0
whereas V
1
I
gave the lowest protein
content (7.45%). So, it can be concluded that the treatment combination of V
0
(Pakchong grass with 3 Irrigations at 20, 40 and 60 days of plantation) can be
considered as the best compared to other treatment combinations and can be
suggested at field level application.
