Abstract:
The experiment was conducted in the Horticulture Farm, Sher-e-Bangla
Agricultural University, Dhaka, Bangladesh, during October, 2013 to March,
2014. The experiment consisted with two factors. Factor A: Pre soaking of
corm with water such as, W
0
; No pre soaking (control), W
; Pre soaking with
normal water and W
2
ii
1
; Pre soaking with hot water and Factor B: Foliar spray of
micronutrient as, F
0
; No foliar spray (Control), F
; Foliar application with 0.25
% Boron and F
2
1
; Foliar application with 0.25 % Zinc. The experiment was laid
out in Randomized Complete Block Design with three replications. Highest
number of floret spike
-1
(11.3) and corm yield (8.8 t ha
-1
) was recorded from
W
2
and lowest number of floret spike
-1
(8.6) and corm yield (5.7 t ha
) from
control. For foliar spray of micronutrient, highest no. of floret spike
(11.0)
and corm yield (8.6 t ha
-1
) was recorded from F
2
-1
-1
and lowest no. of floret spike
(8.8) and corm yield (5.6 t ha
-1
) from control. For interaction effect, highest
number of floret spike
-1
(12.7) and corm yield (10.6 t ha
-1
) was recorded from
W
W
2
0
F
F
2
0
and lowest no. of floret spike
-1
(7.7) and corm yield (4.3 t ha
. From the above result it may be concluded that combination of pre
soaking of corms with hot water and foliar application of 0.25 % Zinc attribute
to more floret and corm yield.
