Abstract:
The study was conducted at the Horticulture Farm of Sher-e-Bangla Agricultural
University, during the period from 8 November, 2013 to 20 February, 2014 in Rabi
season. The experiment consisted of one factor viz. T

kg/ha respectively. The experiment was laid
out in RCBD with three replications. In case of cowdung, zinc and boron
management, the maximum foliage length per plant (75.47 cm), fresh leaves weight
per plant (232.10 g), root length (21.00 cm), root diameter (5.17 cm), percentage
dry matter content of leaves (20.10), fresh weight (160.70 g), dry matter of root
(12.35 %), yield per plot (6.17 kg), yield per hectare (59.67 t) was recorded from T

treatment and the minimum foliage length per plant (60.07 cm), fresh leaves weight
per plant (181.00 g), root length (13.47 cm), diameter of root (3.60 cm), percentage
dry matter content of leaves (15.30), weight of root (117.50 g), percentage dry
matter content of root (8.45 %), yield per plot (2.84 kg) and yield (28.45 t/ha) were
observed from T
treatment. The highest benefit cost ratio (3.34) was noted from
T

treatment and the lowest (2.08) was estimated from T
treatment. From growth,
yield and also economic point of view, it is apparent that T
11
treatment was suitable
for carrot cultivation.
