Abstract:
An experiment was accomplished in the Horticulture farm Sher-e-Bangla
Agricultural University, Dhaka during the period from November 2018- May 2019
to study the influence of thiourea concentrations and application frequency on
growth and yield of light pink lisianthus (Eustoma grandiflorum). Thiourea
concentrations viz., C
1
: 500 ppm, C
2
:1000 ppm, C
3
:1500 ppm and application
frequency, T
0
: Control: No thiourea application, T
1
II
: single application, T
2
: twice
application were used in this experiment arranged in a Randomized Complete
Block Design with three replications. Data on growth, physiology, yield and
quality attributes parameters were taken in which all the treatments showed
significant variations. Among thiourea concentrations, maximum plant height
(59.6 cm), stem number/plant (4.4), flower/plant (26.6), maximum chlorophyll
content (56.6), flower head diameter (6.3 cm), yield/plot (793.2) were recorded
from C
3
and for application frequency, the longest Stem (47.3 cm), peduncle
length (12.7 cm), maximum stem diameter (4.3 mm), flower per plot (898.3) in
twice application (T
2
). Furthermore maximum flower yield per plant (37.3) and
yield per plot (1116.7) were found in C
3
T
2
and minimum yield per plant (10.3),
yield per plot (309.7) in C
0
T
0
. In view of overall observations, twice application of
thiourea at 1500 ppm concentrations had showed the best result and would be the
potential for increasing the lisianthus flower production.
