Abstract:
An experiment was carried out at the Horticultural Farm of Sher-e-Bangla Agricultural
University, Dhaka, during the period of November 2015 to February 2016 to study the
growth, yield and economic benefits of radish as influenced by different organic manures
and mulch materials. The experiment consisted of four levels of organic manure viz. T
=
Control (No manure), T
Mustard oil cake (3 t ha
1
= Cowdung (20 t ha
-1
-1
), T
2
= Poultry manure (15 t ha
) and three levels mulch materials viz. M
= Control (No mulch
materials), M
1
= Black polythene and M
2
0
= Ash. The experiment was laid in Randomized
Complete Block Design with three replications. Combined effect of poultry manure @ 15
t ha
-1
with wood ash as mulch materials represented the best performance in terms of root
length (28.1 cm), fresh weight of root plant
-1
(348.9 g) and fresh weight of whole plant
(513.5 g). Gross yield ha
1
-1
(43.62 t ha
-1
) and the highest marketable yield ha
) were also found with wood ash. Highest net return (240645 Tk ha
-1
) with highest BCR
(3.45) were also found by the same treatment combination.
