Abstract

Bio stimulants are the organic materials that promote the plant growth when applied in minute quantities and are also referred as metabolic enhancers. They have been emerged as a supplement to mineral fertilizers and hold a promise to improve the yield as well as quality of the crop. Keeping in view, the need and importance of biostimulants, an experiment was carried out at the Experimental block of Floriculture and Landscape Architecture, College of Horticulture, Mudigere, Keladi Shivappa Nayaka University of Agricultural and Horticultural Sciences, Iruvakki, Shivamogga in the year 2022- 2023, to investigate the impact of biostimulants on the flowering, quality, and yield of annual chrysanthemum (Chrysanthemum coronarium L.), with ten treatments viz., T1- Humic acid @ 0.4%, T2- Humic acid @ 0.6%, T3- Humic acid @ 0.8%, T4- Biovita @ 0.4%, T5- Biovita @ 0.6%, T6- Biovita @ 0.8%, T7- Biozyme @ 0.4%, T8- Biozyme @ 0.6%, T9- Biozyme @ 0.8% and T10- Control (water). Biostimulants were sprayed thrice (sprayed at 20, 40, and 60 days after transplanting). In randomized complete block design (RCBD), each treatment was duplicated three times. Numerous flowering, quality, and yield indicators were observed. Among all the treatments Biovita @ 0.6% showed earliness in the flower bud initiation (35.66 days), first flowering (40.55 days), 50 per cent flowering (55.35 days) and also, registered the maximum duration of flowering (58.66 days), shelf life (3.66 days), stalk length (15.87 cm), number of flowers per plant (189.26), flower yield per plant (622.66 g), flower yield per plot (22.42 kg) and flower yield per hectare (69.18 tons). However, Biozyme @ 0.8% showed the maximum blossom diameter (6.19 cm), number of petals (72.28), and flower weight (3.44 g). Meanwhile the minimum values for all the parameters were recorded in the control. Thereby, Biovita @ 0.6% showed potential for improving annual chrysanthemum flowering, quality, and yield.

Keywords

Annual chrysanthemum, biostimulants, flowering, quality, yield

Conclusion

Based on the findings of the current study, it can be said that applying Biovita at a rate of 0.6% significantly increased blooming, quality, and yield under open-field conditions. Therefore, the Biovita treatment at 0.6% may be suggested for annual chrysanthemum commercial production.
