Abstract:
A field experiment was accomplished at the Horticulture farm of Sher-e-Bangla
Agricultural University, Dhaka during the period from November 2018 to April
2019 to study the effect of nitrogen doses and spacing on growth and flowering of
Lisianthus (variety-SAU Blue Nandini). Nitrogen doses viz. N

=225 kgha
(BARI
recommended for marigold), N

and Spacing viz. S
1
(30 cm x 15 cm), S
2
(30 cm x 20 cm), S
3
(30 cm x 25 cm) were used in this
experiment arranged in a Randomized Complete Block Design with three
replications. Data on different growth, flower yield and quality attributes
parameters were taken in which all the treatment showed significant variations.
Among nitrogen doses, maximum stem number per plant (5.8), peduncle length
(13.4 cm), flower head diameter (6.2 cm), flower number per plant (42.6), petal
number per flower (19.8) were found from N
3
whereas minimum in N
1
. Among
different spacing, maximum stem number per plant (6.5), stem length (58.4 cm),
flower head diameter (6.0 cm), flower per plant (42.3) found in wider spacing S
3
whereas minimum found in S
1
. Maximum flower number per plant (55.3) were
found in N
3
S
3
and minimum flower number per plant (14.6) were found in N
1
.
The study showed that the higher nitrogen doses with wider spacing would be the
potential for Lisianthus production.
