Abstract:
The experiment was carried out at the farm of Sher-e-Bangla Agricultural
Univervisty, Dhaka, under the Department of Soil Science, during November 2018 to
February, 2019 to study the effect of potassium and magnesium application on the
growth and yield of potato. The experiment consisted of two factors viz. Factor A –
three K levels as K
0
= Control (0 kg K ha
-1
), K
ii
1
= 100 kg K ha
-1
1
and Factor B: three Mg levels as M
0
= Control (0 kg Mg ha
-1
and K
), M
and M
2
= 20 kg Mg ha
-1
1
. The experiment was laid out into Randomized Complete
Block Design with three replications. Data were collected on different parameters and
analyzed significantly using MSTAT software. In most of the cases treatment K
(120
kg K ha
-1
) gave the best result and showed highest tuber yield (25.72 t ha
) whereas
the lowest was obtained from control. Similarly, M
1
(10 kg Mg ha
-1
) gave best results
in most of the cases and showed highest tuber yield (22.26 t ha
-1
). The treatment
combination of K and Mg showed significant variation on different growth and yield
parameters of potato. Results revealed that the highest tuber yield (26.56 t ha
) and
stover yield (20.67 t ha
-1
2
= 120 kg K ha
= 10 kg Mg ha
) were recorded from the treatment combination of K
whereas the lowest tuber yield (14.96 t ha
-1
) and stover yield (17.44 t ha
) were
recorded from the treatment combination of K
