Abstract:
The field experiment was conducted during the period from November 2017 to
March 2018 at Horticultural farm of Sher-e-Bangla Agricultural University, Dhaka.
The variety “Diamant” was used as a test crop. Four levels of potassic fertilizer (KCl)
viz. K
0
: (Control), K
1
: 110 kg/ha,
K
2
: 140 kg/ha, K
: 170 kg/ha and three types of
mulches viz. M
0
: (Control), M
1
: Straw, M

: Black polythene was used for the present
study. The experiment was laid out in Randomized Complete Block Design with
three replications. Different potassium level showed significant influence on most
of the parameters and the treatment. The highest yield (27.20
t ha
-1
) of potato was
obtained in K
2
treatment where
as
the lowest (12.25 t ha
-1
) was obtained from K
.
For mulches, the highest yield (24.57 t ha
-1
) was obtained in M
and the lowest (17.68
t ha
-1
) was obtained from the M
0
1
treatment
. In terms of combined effect of potassium
and mulching, most of the studied parameters were influenced significantly. The
highest yield (31.75 t ha
-1
) was recorded from the treatment combination of K
whereas the lowest yield (9.74 t ha
-1
) was found in the treatment combination K
. So, 140 kg/ha potassium fertilizer with straw mulch gave the maximum yield.
