Abstract:
A field experiment was conducted at the Sher-e-Bangla Agricultural University farm,
(Tejgoan soil series under AEZ 28) during Rabi season of October 2019-March 2020 to
evaluate the effect of potassium (K) and boron (B) on the growth and yield of chili
(Capsicum annuum L.). Two factor experiment with three rates of K (0, 75 and 100 kg K
ha
-1
) and three rates of B (0, 1.5 and 3 kg B ha
-1
) was laid out in the Randomized
Complete Block Design (RCBD) with three replication. Application of K and B
significantly influenced the number of leaves plant
-1
, number of fruits plant
, yield and
other yield parameters of chili. The maximum number of leaves plant
(50.9) and
number of branches plant
-1
(9.2) were observed in K
2
B
2
treatment combinations. The
maximum number of flowers plant
-1
(119) and maximum number of fruits plant
(107.9)
were recorded in K
2
B
0
treatment
combination. The maximum height of plant (33 cm) and
fruit length (6.7 cm) were recorded in K
1
B
1.
Highest weight of fruits as well as highest
yield (10.74 t/ha) was obtained in treatment combination K
1
B
2
. The results of this
research work indicated that the plants performed better in all parameters over the control
treatment (K
0
B
0
). Yield of chili was found maximum in K
1
B
2
treatment which was said
to be the optimum dose of K and B among the treatment combinations and that was cost
effective as well than K
2
B
2
which produced the similar yield
as K
2
B
1.
So, It can be
therefore, concluded from the above study that the treatment combination K
1
was
found to a promising practice for the higher yield of chili in AEZ 28 (Madhupur Tract).
