Abstract:
The experiment was conducted at the research farm of Sher-e-Bangla Agricultural
University, Dhaka, Bangladesh from November 2016 to March 2017. The
experiment comprised as two factors, factor A four levels of micronutrients i.e. M
0
=
Control, M
1
= (Zn 50 mg, Mg 200 mg, Ca 400 mg), M
2
= (Zn 100 mg, Mg 300 mg,
Ca 500 mg), M
3
= (Zn 150 mg, Mg 400 mg, Ca 600 mg) and factors B three levels of
depth of planting i.e. D
1
= 6 cm, D
2
= 9 cm and D
3
= 12 cm. The experiment was
conducted following RCBD with three replications. The maximum number of spike
(3,11,000 /ha) and corm yield (11.93 t/ha) was recorded in M
2
while the minimum
number of spike (1,52,000 /ha) and corm yield (4.88 t/ha) was recorded in M
0
. For
depth, the maximum number of spike (3,09,000 /ha) and corm yield (11.73 t/ha) was
recorded in D
2
while the minimum number of spike (1,96,000 /ha) and corm yield
(6.83 t/ha) was recorded in D
1
. For Combination the maximum number of spike
(3,73,000 /ha) and corm yield (15.06 t/ha) was recorded in M
2
D
2
while the minimum
number of spike (1,20,000 /ha) and corm yield (6.80 t/ha) was recorded in M
0
. So,
Zn 100 mg, Mg 300 mg, Ca 500 mg in 9cm depth was the best for growth, flowering
and corm production of Gladiolus.
