Abstract:
The experiment was conducted in the Horticulture Farm of Sher-e-Bangla
Agricultural University, Dhaka, during the period from December 2019 to July 2020
to study the influence of organic amendments and bio-control agent on growth and
yield of gerbera. The single factor experiment consisted of five treatments namely:
T
1
= Farmyard manure (3 t/ha) + ¼ RDF, T
2
= Vermicompost (3 t/ha) + ¼ RDF, T
3
=
Trichocompost (3 t /ha) + ¼ RDF, T
4
= Tricholeachate (3000 L/ha) + ¼ RDF and T
5

kg/ha). The
experiment was conducted in Randomized Complete Block Design with three
replications. Application of organic manure, chemical fertilizer and bio-control agent
showed significant variations on most of the parameters. Result revealed that
maximum vegetative and flowering characters were recorded in T
3
= Trichocompost
(3 t/ha) + ¼ RDF which were statistically superior to other treatments. T
3
produced
maximum plant height, number of leaves per plant, plant spread and number of
suckers per plant. Days taken to flower bud initiation and full bloom from bud open
varied greatly among cultivars under the study. T
3
took least number of days for bud
initiation (68.33 days) and full bloom (7.15 days) respectively. For flower
characteristics, T
3
showed the maximum number of ray floret (48.0), the longest
flower stalk (57.11 cm), maximum flowers per plant (12.70) and possessed the
longest vase life (14.67 days). The largest flower diameter (10.78 cm) was found in T
3
and the smallest was in T
5
(8.07 cm). Considering the important characteristics, the
data obtained from the experiment showed that trichocompost with fertilizer enhanced
qualitative and quantitative characters of gerbera.
