Abstract:
A heW experiment was carried out to investigate the perlormance of ditterent varieties and
different fertilizer management practices on the growth and yield of Knol-khol at the
Horticulture farm of Sher-c-Bangla Agricultural University. Dhaka during the period from
October, 2007 to January, 2008. The experiment consisted of five varieties, viz. V,: White
vienna: V2: Quick star; V
3: Sufala-14; V
4
: tWO: V
ç: Early 005 and Ibur kinds of fertilizer
management practices,
viz.
F0
: Control; F
1
: Organic Manure; F
2
: Inorganic fertilizer; F3:
Organic fertilizer
Inorganic fertilizer. The experiment was carried out in randomized
complete block design with three replications. Both variety and fertilizer management
practices had significant influence on growth and yield, in case of varieties. V
1 showed
highest marketable yield (29.39 t/ha) and V
5
the lowest (22.43 t/ha). For fertilizer, the
maximum marketable yield (31.78 t/ha) was found in F
3
and the lowest (18.99 t/ha) in F
0.
For combined effect, the highest marketable yield (37.51 t/ha) was obtained from V
1 F 3 and
the lowest (16.31 t/ha) from V
5F 0
. Maximum net return (200730.62 11./ha) and benefit cost
ratio (3.02) were thund from V
1 F 3
and the lowest from V,F
0
. So. highcr yield could be
obtained by cultivating the Vhite vienna of Knol-khol with both organic and inorganic
fertilizers under the Madhupur tract of Bangladesh.
