Abstract
Gladiolus (Gladiolus hybridus Hort.) is one of the most popular cut flowers and it
belongs to Iridaceae family. It is popularly known as Queen of bulbous flowers because of
its beautiful spikes having diverse range of colours and longer keeping quality. It is grown
for use as cut flower, garden decoration, pot plant, herbaceous borders and making highquality bouquets. During 2022-23, an experiment was conducted at Department of
Floriculture and Landscape Architecture, College of Horticulture, Banda University of
Agriculture & Technology, Banda. Experiment was laid out in Factorial Randomized Block
Design (FRBD) with three replications. The purpose of experiment was to study the effect
of silicon application on vegetative growth, flowering and corm production in gladiolus. In
the experiment, soil application of silicon (2.9, 5.9 and 8.8 g/m2
) was done before planting
and foliar application of silicon was done @ (1% (4.7 g/m2
) and 2% (9.4 g/m2
) at 3 and 6
leaf stage. All the growth and yield parameters were periodically observed. Analysis of
results showed significant results for leaf area (63.01 cm2
), number of florets per spike
(13.42), floret size (9.9 cm), rachis length (52.51 cm), fresh weight of spike (59.01 g), vase
life (13.22 days), weight of corm per plant (20.70 g) and weight of cormels per plant (11.40
g) in soil application of silicon i.e. S4 (8.8 g/m2
). Among the foliar applications of silicon
i.e., F3 2% (9.4 g in 400 ml water/m2
area) recorded maximum leaf area (63.83 cm) and
weight of corm per plant (20.25 g). Whereas, maximum number of cormels per plant (69.79)
and water uptake (85.85 ml) was recorded in F1 (control). Among the different soil and foliar
application of silicon, combination S4F1 recorded maximum plant height at 60 DAP and 75
DAP (53.87 cm and 58.90 cm), length of longest leaf (40.32 cm), number of florets per spike
(13.86), rachis length (55.81 cm) and duration of flowering (15.73 days). Whereas,
maximum leaf area (67.26 cm2
), number of spike per plant (1.60), fresh weight of spike
(61.33 g), vase life (13.50 days) and weight of cormels per plant (16.73 g) was recorded in
S4F3 treatment combination.
