Abstract:
An experiment was conducted at Sher-e-Bangla Agricultural University, Dhaka, Bangladesh
during the period from November, 2019 to January, 2020 to evaluate the effect of organic
manures and biochar on growth and yield of celery. The experiment consisted of two factors:
Factor A: Organic Manures (four levels) as OMo: Control i.e., no manure, OM,: Vermicompost
@3.5 tlha, OM2: Cowdung @10 tlha, OM3: Trichocompost (@1.5t1ha)
trichoderma treated with Vermi-compost Factor B- Biochar (three levels) Bo: Control,
B1: Biochar @4 t/ha, B2: Biochar @2 tlha. The two factors experiment was laid out in .
Randomized Complete Block Design (RCBD) with three replications. Significant variation
was found with the treatments. In case of combined effect of organic manures and biochar,
maximum fresh weight of leaves was achieved from OM3B, treatment (154.90 g) and
marketable number of leaves at 55 DAT was highest at OM3B, treatment (23.22). For
combined effect of organic manures and biochar, length of celery leaves was highest at
OM3BJ which was statistically similar with OM3B2. Economic analysis revealed that OM3BI
gave the maximum gross return and net return with significant benefit cost ratio (2.51). So,
considering all, it can be concluded that, OM3 treatment Trichocompost@ 1.5 tIha)
combined with BJ Biochar@ 4 tlha) provided the best result for growth and yield of celery
for commercial cultivation in Bangladesh.
