Abstract:
An experiment was carried out in the Horticulture Farm of Sher-e-Bangla Agricultural
University, Dhaka, to investigate the impact of biochar application on growth and
yield of eggplant from October 2020 to February 2021 during the Rabi season. The
experiment was set up in a randomized complete block design (RCBD) with seven
treatments, including i.e., B
: No BC (Biochar) + 100% recommended dose of
fertilizer (RDF), B
1
0
: 2 t/ha BC + 100% RDF, B
X
2
: 2 t/ha BC + 90% RDF, B
: 3 t/ha BC
+ 100% RDF, B
4
: 3 t/ha BC + 80% RDF, B
5
: 4 t/ha BC + 100% RDF and B
: 4 t/ha
BC + 70% RDF. Different growth and developmental parameters were collected for
the purpose of the evaluating experimental outcomes. Result of the experiment
revealed that different doses of biochar application had significantly influenced plant
height, number of leaves plant
-1
, leaf length plant
-1
and leaf breadth plant
at different
days after transplanting. Among the different doses of biochar application, the B
treatment produced the highest number of flowers plant
-1
(51.74), number of fruits
plant
-1
(28.88), fruit length plant
-1
(11.12 cm), fruit diameter plant
(7.74 cm),
individual fruit weight plant
-1
(170.50 g), yield plant
-1
(16.53
kg) and yield (49.20 t ha
-1
-1
-1
(4.92 kg), yield plot
). However, the second highest fruit yield (38.50 t ha
) was
recorded from B
6
treatment followed by B
3
(35.40 t ha
-1
) treatment and the minimum
fruit yield (22.50 t ha
-1
) was observed in B
treatment. Therefore, based on the above
findings, it could be concluded that the application of biochar and its combination
with recommended dose of fertilizers (4 t/ha BC + 100% RDF) showed better
performance on the growth, yield, and yield attributing traits of eggplant.
