Abstract:
The experiment was conducted at Sher-e-Bangla Agricultural University, Dhaka
from October 2018 to March 2019 to assess the effect of chemical and organic
fertilizers on growth, yield and phenolic contents of tomato. The experiment
consisted single factor: five fertilizer management practice with chemical and
organic fertilizer (cowdung) viz. T
1
: Local Control, T
2
: 100% Chemical
fertilizer, T
3
: 75% Chemical fertilizer +25% Organic fertilizer, T
4
: 50%
Chemical fertilizer + 50% Organic fertilizer, T
5
: 100% Organic fertilizer. The
experiment was laid out in Randomized Complete Block Design (RCBD) with
three replications. Different fertilizer management practices influenced
significantly on all of the studied parameters. Among the fertilizer management
practices T
3
treatment
(75% Chemical fertilizer +25% Organic fertilizer)
performed best in case of all of the vegetative (Plant height, number of leaves,
number of branches) and reproductive characteristics (days to flowering, number
of clusters, number flowers and fruits per cluster, number of fruits per plant).
Fruit length, fruit weight was also observed highest from T
3
treatment and lowest
from T
1
treatment. Maximum yield was obtained from T
3
treatment (3.30
kg/plant and 93.2 t/ha) and lowest was found from T
1
treatment (2.10 kg/plant
and 76.8 t/ha). Phenolic content of tomato pulp and seed was highest for T
5
treatment (49.87 mg GAE/100g and 24.76 mg GAE/100g) and the lowest
phenolic content was found from T
1
33.30 mg GAE/100g and 14.31 mg
GAE/100g).
