Abstract:
The present investigation was carried out to study the effect of organic manure,
inorganic fertilizer and bio-control agent on yield and quality of gladiolus at the
Floriculture Research Field, BARI, Gazipur from October, 2014 to May 2015. The
single factor experiment consisted of eight treatments namely: T

: Vermicompost (5 t/ha) + Trichocompost
(3 t/ha) + ¼ RDF. 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 early sprouting of corm (8 days) was recorded from treatment
T
6
. The treatment T
has taken the minimum period (68 days) for 80% spike
initiation. The maximum length of spike (80.0 cm) and rachis (34.0 cm), number
of florets/spike (16), number of spikes/ha (200000) was registered with the
treatment T
8
7
. However, the highest number (2.5/hill) and weight of corm (60.0 g)
and cormel per plant (20.0) was recorded with treatment T
. So, application of
Vermicompost (5 t/ha) and Trichocompost(3 t/ha) with ¼ RDF showed best result
on yield and quality of gladiolus.
