Abstract:
A pot experiment was conducted in the semi-greenhouse at the Horticulture Farm of Sher-e-
Bangla Agricultural University, Dhaka 1207, Bangladesh, during October 2019 to March 2020
to find out the best combination of calcium fertilizers and different varieties for successful
cherry tomato production. The experiment consisted of two factors: Factor A: three types of
variety viz. V
1
= Red Star F
1
; V
2
= Sweet Charlie F
1
; V
3
= Thai Pink Egg and Factor B: Four
doses of calcium fertilizer viz. C
1
= 0 ppm; C
2
= 40 ppm; C
3
= 80 ppm; C
4
= 120 ppm. There were
12 treatment combinations and experiment was setup in Completely Randomized Design (CRD)
with three replications. In case of varieties, the highest plant height at 60 DAT (255.32 cm),
maximum branch number per plant (4.58) at 60 DAT, maximum chlorophyll content (75.71 %)
at 75 DAT, minimum days required for first flowering (27.67 DAT) and first fruiting (36.33
DAT), maximum flower cluster per plant (30.83), maximum fruit number per plant (284.56),
highest single fruit weight (10.52 g), highest amount of TSS (8.90 degrees Brix) and yield per
plant (2.94 kg) were obtained from V
2
treatment. Similarly, in case of calcium fertilizer, the
highest plant height at 60 DAT (233.92 cm), maximum branch number per plant (4.78) at 60
DAT, maximum chlorophyll content (81.53 %) at 75 DAT, minimum days required for first
flowering (25.33 DAT) and first fruiting (33.89 DAT), maximum flower cluster per plant
(35.28), maximum fruit number per plant (292.77), highest single fruit weight (11.61 g), highest
amount of TSS (8.96 degrees Brix) and yield per plant (3.32 kg) were obtained from C
2
treatment. In combined effect, the highest plant height at 60 DAT (273.33 cm), maximum
branch number per plant (5.67) at 60 DAT, maximum chlorophyll content (86.77 %) at 75 DAT,
minimum days required for first flowering (24.00 DAT) and first fruiting (32.00 DAT),
maximum flower cluster per plant (36.67), maximum fruit number per plant (362.02), highest
single fruit weight (13.33 g), highest amount of TSS (9.47 degrees Brix) and yield per plant
(4.34 kg) were obtained from V
2
C
2
treatment. Among the treatment combination, V
2
(Sweet
Charlie F
1
variety with 40 ppm Ca) treatment seemed to be more promising for obtaining higher
yield of cherry tomato.
