Abstract:
An experiment was conducted at the farm of Sher-e-Bangla Agricultural University,
Dhaka during the period from November, 2017 to February, 2018. The experiment
consisted of two factors, Factor A: four levels of manure, O
0
: no manure, O
:
Cowdung (20 t/ha), O
2
: Vermicompost (10 t/ha) and O
: Cowdung (10 t/ha) +
Vermicompost (5 t/ha) and Factor B: four mulches, M

0
: No mulch, M
: Water
hyacinth, M

: Black polythene and M
: Wood ash, respectively. The experiment was
laid out in Randomized Complete Block Design with three replications. Manure and
mulching influenced significantly all the studied parameters. In case of manure the
maximum plant height (44.55 cm) root length (14.74 cm), root diamter (4.12 cm), root
weight (124.50 g), root yield (24.90 t/ha) and marketable root yield (23.85 t/ha) were
recorded from O

treatment. In case of mulches, maximum plant height (44.81 cm),
root length (15.21 cm), root diameter (3.92 cm), root weight (117.85 g), root yield
(23.57 t/ha) and marketable root yield (21.95 t/ha) found in M
treatment. The
combined effect of highest root yield (29.07 t/ha) was obtained from O

and lowest
(13.20 t/ha) from O

(control). The highest gross return (Tk. 563200), net return
(Tk. 446355) and BCR (4.82) were obtained from the treatment combination from

10 t/ha vermicompost with black polythene mulch was the best for carrot cultivation.
