Abstract
The investigation on “Studies on the effect of foliar nutrients and GA3
along with bio-fertilizers on growth, flowering and vase life of Anthurium
(Anthurium andreanum Lind.) cv. Tropical Red” was carried out during the
year 2009 – 2010 at ZARS Division of Horticulture, Gandhi Krishi Vignana
Kendra, University of Agricultural Sciences, Bengaluru. The experiment was
conducted under 70% shade net with 11 treatments and 3 replications
following Completely Randamized Design, with different combinations of GA3
(0ppm, 50ppm, 100ppm, 200ppm and 300ppm) and foliar nutrients (N at
two levels, P at two levels and K at constant level) along with biofertilizers
(Azospirillum, PSB and VAM at 2gm each per plant). Application of NPK at 30:10:10 at the rate of 0.2% spray, GA3 at 100 ppm along with application of biofertilizers (Azospirillum, PSB, VAM each at 2 g/ plant) recorded significantly maximum plant height (26.43 cm),
maximum number of leaves (9.73) and leaf area (253 cm2), highest number
of suckers per plant (3.50), early flower bud appearance and least number of
days to flower opening (61.20 days and 12.00 days respectively), maximum
number of flowers per plant and flower yield per m2 (4.46 and 34.00
respectively) and flower quality characters like spathe length and width (7.1
cm and 7.96 cm respectively) was significantly maximum with longest
spadix (6.73 cm), highest spadix girth (1.22 cm), maximum stalk length (24
cm) and stalk girth (0.48 cm) and longest vase life (19.33 days) was observed
in the same treatment combination. Of all the treatments, application of NPK at 30:10:10 at the rate of 0.2% spray, GA3 at 100 ppm along with application of biofertilizers
(Azospirillum, PSB, VAM each at 2 g/ plant) proved to be the best in Anthurium andreanum Cv, “Tropical Red” for improving vegetative growth, flowering and vase life characters.
