Abstract:
The experiment was carried out at the research field, Sher-e-Bangla Agricultural
University, Dhaka-1207, from November 2021 to February 2022 to study the effect of
phosphorous and boron on the growth and yield of potato (Solanum tuberosum). Three
levels of phosphorous (P
0
= 0 kg P ha
ii
-1
, P
1
= 30 kg P ha
-1
, P
2
= 40 kg P ha
) and three
levels of boron (B
0
= 0 kg B ha
-1
, B
1
= 2 kg B ha
-1
, P
2
= 3 kg B ha
-1
) were used for this
study. The experiment was carried out using RCBD with nine treatment combinations and
three replications. The data on growth and yield parameters of potato were recorded. Most
of the parameters were significantly affected by different levels of P application. Generally,
P
2
gave the best results and showed the highest tuber yield (30.47 t ha
-1
), and marketable
yield (26.63 t ha
-1
). Most of the parameters were also significantly affected by boron
treatments. The highest yield (28.92 t ha
-1
-1
), and highest marketable yield (25.3 t ha
)
resulted from B
2
treatment. Considering the combined effect of P and B the maximum plant
height (50.70 cm), number of stems (6.17), number of leaves
hill

(109), number of tubers

(7.33), weight of tubers hill

(552.10 gm), weight of tubers plot

(13.57 kg), yield
(33.99 t ha

), marketable yield (29.54 t ha
-1
), tuber length (18.70 cm) and tuber width
(16.13 cm) resulted from the P

B

treatment combination. On the other hand, the minimum
plant height (38.10 cm), number of stems hill

(3.17), number of leaves hill
(51.53),
number of tubers hill
-1
(4.38 kg), yield (10.97 t ha
(4.17), weight of tubers hill

-1
-1
(181.33 gm), weight of tubers plot
), lowest marketable yield (6.18 t ha
-1
), tuber length (15cm),
and tuber width (12.13 cm) were recorded from P
0
B
0
(control) treatment combination. So,
considering the aforementioned findings, P
2
treatment (40 kg P ha
-1
) with B
2
treatment (3
kg B ha
-1
) performed the best results for the growth and yield of potato.
