Abstract:
The study was conducted at the Horticultural Farm of Sher-e-l3angla Agricultural University,
Dhaka, Bangladesh during the period from October. 2007 to June. 2008 to find out the effect
of spacing and concentration of Chlorocholinc Chloride (CCC) on growth, production and
shelf life of gladiolus. The experiment consisted of two factors. Factor A: Three levels of
plant densities i.e S,: 25 cm x
15 cm; S2: 25 cm
x
20cm and S
3 : 25 cm
X
25 cm and Factor
B: Four levels of Concentration of CCC i.e C
O : 0; C1
: 200; C
2 : 400 and C
3: 600 ppm
respectively. The experiment was laid out with Randomized Complete Block Design with
three replications. In case of plant densities the highest flowering plant (93.67%), yield of
corm (17.06 tilia) and cormel (14.08 tlha) was recorded from
S2
and the lowest from S1. In
case of CCC the highest flowering plant
(93.89%).
shelf life (15.78 days), cormel per plant
(22.54), yield of corm (16.20 L/ha) and cormel (14.40 t/ha) was recorded from C. and the
lowest from C
o
. For interaction effect, the highest flowering plant (98.33%). shelf life (16.67
days), comicl per plant (25.02), yield of corm (18.21 r/ha) and cormel (16.23 lJha) was
recorded from S2C2
and the lowest from SICI). The highest benefit cost ratio (2.21) was
obtained from the combination of S
2C2
. So, it may be concluded that 25 cm x 20 cm plant
density with 400 ppm CCC is suitable for growth, production and shelf life of gladiolus.
