Abstract:
A field experiment was conducted at the Horticulture farm of Sher-e-Bangla Agricultural
University, Dhaka during the period from November 2017 to February 2018. The exper i-
ment was laid out in a Randomized Complete Block Design with three replications. Three
mulching treatments viz. M
0
: No mulch, M
1
: Rice straw and M
: Black polythene and four
levels of nitrogen viz. N
0
: 0 kg N ha

: 80 kg N ha

were considered for the present study. Different mulching treatments and nitrogen
doses and also their combinations showed significant influence on different growth, yield
contributing parameters and yield of squash. The treatment, M
showed highest results in
individual fruit weight (456.80 g), and fruit yield ha
-1
(20.20 t ha

-1
) compared to control. In
case of nitrogen treatments, the highest results in individual fruit weight (512.54 g) and
highest fruit yield ha
-1
(26.79 t ha
-1
) were found from N
compared to control. Likewise,
the treatment combination of M

N

gave the highest individual fruit weight (522.00 g) and
fruit yield ha
-1
(28.95 t ha
-1
) where the lowest results were found from the treatment combination
of
M
0
N
. The highest gross return (Tk 434250), net return (Tk 305430) and BCR
(3.37) were obtained from the treatment combination of M
0
2
N
where the lowest was obtained
from M

and N
. So, it can be concluded that black polythene mulch with 130 kg N ha
is suitable for squash cultivation.
