Abstract:
An experiment was conducted at the Horticulture Farm of Sher-eBangla
Agricultural
University,
Dhaka
during
the
period
from
November
2011
to
February
2012
to
evaluate
growth
and
yield
of
carrot as influenced by different types of organic manures (O
organic manure, O
c:
cowdung and O
vermicompost ) and neem
products (N
0:
no neem products, N
1:
v:
neem leaf powder and N
neem
oil cake) . The experiment was conducted in Randomized
Complete Block Design with three replications. Application of
organic manures and neem products significantly influenced the
growth and yield contributing parameters. For organic manures, O
gave the highest gross yield (33.33 t/ha) and marketable yield
(32.20 t/ha) whereas, O
produced the lowest gross yield (15.84
t/ha) and marketable (12.50t/ha) yield. The highest gross yield
(27.89 t/ha) and marketable (25.60 t/ha) yield was obtained from
N
1
and the lowest from N
0
0
. For combind effect N
1
O
produced the
highest marketable yield (29 t/ha) whereas, the lowest (09.00 t/ha)
from N
0
O
0
v
. The maximum benefit cost ratio (3.37) was obtained
from O
c
N
1
and minimum (1.42) from N
0
O
. So, it may be
concluded that cowdung with neem leaf powder was found suitable
for growth and yield of carrot.
