Abstract

A field experiment was conducted to evaluate the effect of dosage and application schedule of gibberellic acid and benzyl adenine on growth parameters in gypsophila cv. Star World during kharif 2019-2020 at Floricultural Research Station, ARI, Rajendranagar. The soil of experimental plot was sandy loam with good drainage and moderately low water holding capacity. The soil pH is 7.2 and E.C. is 0.27 dSm-1. The available nitrogen of the soil is at 200.30 kg/ha, phosphorous at 45 kg/ha and potassium at 168.75 kg/ha. The experiment consisted of growth regulators GA3 and BA at 150, 300 and 450 ppm, water spray and two schedules of application at 30 and 45 days after pruning. The experiment was laid out in completely randomized block design with factorial concept with fourteen treatments replicated twice. The experiment results revealed that (G3S2) GA3 at 450 ppm and double spray recorded maximum plant height (98.29 cm), plant spread in E-W direction (54.50 cm), plant spread in N-S direction

Keywords

Gypsophila, gibberellic acid, benzyl adenine, growth parameters.

Conclusion

Based on the above findings among the interactions foliar application of GA3 at 450 ppm + double spray and BA at 150 ppm + double spray was proved most effective in increasing the growth parameters of gypsophila.
