Abstract
The study was conducted at the Horticulture Farm, Sher-e-Bangla
Agricultural University, Dhaka, Bangladesh during the period from May-Oct. to
study the influence of spacing on growth, flowering, corm and cormel production
of gladiolus (Gladiolus grandiflorus
l.). The experiment consisted of three levels of spacing (S1: 30 cm × 20 cm; S2:
30 cm × 25 cm and S3:
30 cm × 30 cm). The maximum number of florets per spike (15.0) was recorded
from S2, while the minimum (11.3) was observed in S1. The
maximum number of spike per hectare (277 thousand) was recorded from S2,
while the minimum (225 thousand) from S1. The highest yield of corm
(14.9 t
ha–1) was recorded from S3,
while the lowest yield (10.6 t ha–1) was observed from S1. The highest yield of cormel (12.1 t
ha–1) was observed from S2,
while the lowest yield (8.1 t ha–1) was found from S1.
Key words: spacing, gladiolus, flower, corm and cormel
