Abstract:
The experiment was conducted in the Horticulture Farm, Sher-e-Bangla
Agricultural University, Dhaka during October 2015 to February 2016. The
experiment consisted of two factors, such as Factor A: four levels of
micronutrients i.e. T
0
: No micronutrients, T

kg/ha and Factor B: mulching materials (3 levels) as- M

:
No mulch (control), M

: Water hyacinth, M
2
: Black polythene. The two factorial
experiment was laid out in Randomized Complete Block Design with three
replications. Micronutrients and mulching influenced significantly on most of
the parameters. In case of micronutrients, the highest curd yield (24.20 t/ha) was
found from T
3
and the lowest curd yield (18.44 t/ha) was found from T
0
. For
mulching, M
2
performed the highest curd yield (25.23 t/ha) and the lowest
(15.29 t/ha) was from M
0
. For combined effect, the highest curd yield (28.76
t/ha) was obtained from T
3
M
2
and the lowest curd yield (12.97 t/ha) from T
0
.
The highest benefit cost ratio (2.14) was noted from the combination of T
3
and the lowest benefit cost ratio (1.09) from T
