| An experiment
was conducted to assess the effect of spacing and nitrogen levels on
flowering, flower quality and vase life of gladiolus cv. Red Beauty.
Four spacings (15 x 30, 20 x 30, 25 x 30 and 30 x 30 cm) and four
nitrogen rates (0, 100, 200 and 00 kg/ha) were taken. Corms planted at
25 x 30 cm and 200 kg N/ha significantly increased the diameter of
spike, number of florets per spike, number of spikes per plant and
number of spikes per ha and early emergence of spike under field
conditions (Nagaland, India). Application of 200 kg N/ha also resulted
in maximum length of spike and diameter of floret. However, early
opening of flower was recorded with lower N rate (100 kg/ha), while
length of floret with 300 kg N/ha. Spacing and N levels had significant
effect on postharvest life of cut gladioli. Spacing 25 x 30 cm had
striking effect on percent opening of florets per spike, number of open
florets with drooping of minimum florets. N at 200 kg/ha had significant
effect on percent opening of florets per spike, number of open florets
per spike and water uptake during vase life |
