Abstract
A field experiment was conducted at the research farm of Sher-e-Bangla Agricultural
University, Dhaka-1207 during the period from September, 2018 to March, 2019 to
find out the influence of vermicompost and plant density on growth and quality seed
yield of coriander. The variety BARI Dhonia 1 was used in the experiment as the test
crop. The experiment consisted of two factors: Factor A: three different plant
densities viz. P
1
= 20 plants/m
2
, P
2
= 40 plants/m
2
, P
3
= 80 plants/m
and Factor B:
four levels of vermicompost viz. V
0
= 0 t/ha, V
1
= 5 t/ha, V
2
2
= 10 t/ha and V
= 15
t/ha. There were 12 treatment combinations and experiment was setup in Randomized
Complete Block Design (RCBD) with three replications. The result indicated
significant variations in plant height, number of primary branches per plant, number
of umbels per plant, umbellate per umbel, number of seeds per plant, dry seed weight
per plant, dry seed weight per plot, seed yield, germination percentage, electric
conductivity test value, seedling root length and shoot length due to different plant
density and/or vermicompost application. Results also revealed that, 40 plant/m
)
treatment significantly influenced the morphological characters, yield contributing
characters and seed quality of coriander. The highest germination percentage (77.33
%) was also obtained from this treatment but 80 plant/m
2
(P
) treatment significantly
influenced on yield which gives highest seed yield (2.66 t ha
3
-1
) due to its high plant
density. Results also revealed that, application of 15 t ha
-1
3
vermicompost (V
)
treatment significantly influenced the morphological characters, yield contributing
characters, yield and seed quality of coriander. The highest seed yield (2.71 t ha
) and
germination percentage (78.66 %) was also obtained from this treatment. Among the
treatment combination, P
3
V
3
(80 plant/m
2
with 15 t/ha vermicompost) treatment
seemed to be more promising for obtaining higher yield (3.33 t ha
-1
) but application of
15 t ha
-1
of vermicompost with 40 plants m
-2
(P
2
V
) combination seemed to be more
suitable for getting quality seed production of coriander. .
