Abstract:
The experiment was conducted at the Sher-e-Bangla Agricultural University Farm,
Dhaka, (AEZ -28), Bangladesh during November 2019 to February 2020 to study the
effect of nitrogen and boron fertilizer on yield components and yield of potato (Solanum
tuberosum). Three nitrogen levels; N
0
= 0 kg N ha
-1
, N
1
= 100 kg N ha
, N
2
= 150 kg
N ha
-1
and N
3
= 200 kg N ha
-1
and four Boron levels; B
0
= 0 kg B ha
-1
and B
2
= 2 kg B ha
-1
were considered for the present study. The experiment was laid out
in the two factors Randomized Complete Block Design (RCBD) with three replications.
Data on different growth, yield components and yield of potato were recorded. Most of
the parameters were significantly influenced by different levels of N application. The
highest tuber yield ha
-1
(22.22 t) and marketable yield ha
-1
(20.96 t) were found from
the treatment N
2
(150 kg N ha
-1
) compared to control treatment N
0
(0 kg N ha
). Boron
treatment also significantly influenced all the studied parameters and the highest tuber
yield ha
-1
(21.73 t), and marketable yield ha
-1
(20.32 t) were achieved from the treatment
B
2
(2 kg B ha
-1
) compared to control treatment B

(0 kg B ha

). Considering combined
effect of N and B, the highest plant height (67.26 cm), number of stem hill
