Abstract:
A field experiment was conducted at Horticulture Farm of Sher-e-Bangla
Agricultural University, Dhaka, to study the effect of calcium and zinc in green
chilli production (cv. BARI Morich 2). The experiment consisted of two factors,
viz., Factor A: four levels of calcium (Ca
ii
0
: 0 kg ha
-1
, Ca
1
: 19 kg ha
: 27 kg
ha
-1
and Ca
3
: 35 kg ha
-1
) and Factor B: three levels of zinc (Zn
0
-1
: 0 kg ha
: 2.5
kg ha
-1
and Zn
2
: 5.0 kg ha
-1
).Vegetative growth, yield Contributing characters and
yield were measured during the experiment. In case of calcium, the highest
number of flowers plant
-1
(69.65), number of fruits plant
-1
(59.63), average fruit
weight (2.66 g), fruit yield plant
-1
(243.60 g) and fruit yield ha
-1
(10.30 t) were
recorded in treatment of Ca
2
(27 kg ha
-1
)
meanwhile, the lowest values of the
above mentioned parameters were found in the control.

On the other hand, in case
of zinc, the highest number of flowers plant

(71.90), number of fruits plant
(62.18), average fruit weight (2.84 g), fruit yield plant

(257.10 g) and fruit yield

(10.90 t) were recorded in treatment of Zn

(2.5 kg ha

),
meanwhile, the
lowest values of the above mentioned parameters were found in the control. In
case of interaction effect, the highest values of the above mentioned parameters
were found in Ca

Zn
1.
The highest Benefit Cost Ratio (3.69) was also found from
Ca

treatment combination. Therefore it can be concluded that 27 kg ha
of
calcium and 3.5 kg ha
-1
of zinc were found beneficial for growth and yield of
green chili.
