Description The experiment entitled “Effect of gibberellic acid on growth, seed yield and quality of
fennel (Foeniculum vulgar Mill.), was conducted during winter season of 2012-13 at Research
Farm of the Department of Vegetable Science, CCS Haryana Agricultural University, Hisar. The
seed material used for the investigation was a local variety Hisar Swarup (HF -33). In the present
experiment, four different gibberellic acid concentrations including control (0, 50, 75 and 100
ppm) were sprayed at three different stages of crop growth ( juvenile, flowering and initial seed
setting stage). Twelve treatment combinations laid out in Randomized Block Design (factorial)
were replicated thrice making total of 36 plots.
Gibberellic acid application showed significant improvement in all the growth,
yield and seed quality parameters over control. The best results for plant height at harvest,
number of branches per plant at harvest, days to 50 per cent flowering, number of umbels
per plant, number of seeds per umbel, number of seeds per um bellet, biological yield, seed
yield, harvest index, germination percentage, seed vigour index and test weight were
recorded with the application of gibberellic acid at 100 ppm concentration. Stages of
application of gibberellic acid had a significant effe ct on growth, yield and quality
parameters except seed vigour index II. The maximum values for plant height at harvest,
number of branches per plant at harvest, days to 50 per cent flowering, number of umbels
per plant, biological yield, and total seed yie ld were recorded with the application of
gibberellic acid at juvenile stage. The maximum values for number of seed per umbellet,
number of seeds per umbel, harvest index, germination percentage, seed vigour index and
test weight were observed with the gibb erellic acid application at flowering stage.
Interaction of gibberellic acid concentrations with stages of application showed remarkable
variation. Interaction of gibberellic acid 100 ppm applied as foliar spray at juvenile stage
was found to be the best with respect to all growth, and yield parameters except vigour
index II. The best result for quality parameters was observed with the interaction of
gibberellic acid 100 ppm applied at flowering stage.
