Abstract

The experiment was undertaken in Department of Floriculture and Landscape Architecture, College of Horticulture, Junagadh, Junagadh Agricultural university during the academic year 2022-2023, to Determining the optimal dosage and timing of application different level of foliar application of Gibberellic acid (GA3), Naphthalene acetic acid (NAA) and Brassinosteroid (BRs) on spider lily (Hymenocallis littorallis L.) to achieve desired outcomes in terms of flowering, quality, and yield, as these parameters can be influenced by various environmental factors and plant-specific responses. Additionally, ensuring uniform coverage and absorption of the growth regulators across a diverse population of spider lilies can be a logistical challenge in large-scale cultivation. In this experiment, the treatments considered were GA3 (200 ppm and 250ppm), NAA (150 ppm and 250 ppm), BRs (3 ppm and 5 ppm). The experiment was laid out in Randomized Block Design (RBD) with four replications. Results of the experiment showed a significant that GA3 @ 250 ppm recorded maximum spike length(75.37 cm), flower bud length (21.99 cm), flower bud diameter (1.20 cm), flower diameter (22.92 cm), days taken for first spike emergence (52.01 days),number of flower spike per plant (7.30), number of flowers per spike (16.78), number of flowers per plant (119.01), number of flowers harvested per net plot (28.52 bundles), yield of flowers (88032.41 bundles/ha), shelf life of flower (32.06 hour) and in-situ longevity of flower.

Conclusion

In the current study, foliar application of plant growth regulators increased spider lily flowering, quality and yield, and based on the current experimental results, it can be concluded that foliar application of GA3 @ 250 ppm outperformed other plant growth regulator treatments, followed by treatment with GA3@ 200 ppm.
