Abstract:
An experiment was carried out in the Horticulture farm of Sher-e-Bangla Agricultural
University, Dhaka, Bangladesh during the period from October 2017 to April 2018. The
experiment consisted of two factors viz. 3 levels of plant spacing; S
1
: 45 cm × 30 cm; S
2
:
45 cm × 45 cm and S
3
:
45 cm × 60 cm and 4 levels of potassium; K
0
: 0 kg/ha (Control);
K
1
: 60 kg K ha
-1
; K
2
: 90 kg K ha
-1
and K
3
: 120 kg K ha
-1
. The experiment was laid out in
Randomized Complete Block Design with three replications. Data on different growth,
yield contributing characters and yield at different days after transplanting (DAT) were
recorded. Individually plant spacing and potassium had significant effect on growth, yield
contributing parameters and yield parameters of chilli. Plant spacing, S
2
showed highest
fruit yield (21.46 t ha
-1
). Regarding potassium application, K
2
gave highest fruit yield
(20.37 t ha
-1
). Combined effect of plant spacing and potassium also showed significant
effect on growth and yield of chilli. Results revealed that the highest fruit yield (24.62 t ha
1
) was achieved from the treatment combination of S
2
was obtained from the treatment combination of S
1
K
2
K
0
where the lowest fruit yield plant
(16.20 t ha
-1
). Regarding economic
analysis, the highest BCR (3.52) was achieved from the treatment combination of S
2
with higher gross return (Tk. 369300 ha
-1
) and net return (Tk. 264462 ha
) where the
lowest BCR (1.98) was observed from the treatment combination of S
3
. So, it can be
concluded that spacing 45 cm × 45 cm with 90 kg K ha
-1
K
0
-1
is suitable for chilli cultivation.
