Effect of Biostimulants on Growth, Flowering and Yield of Rose (Rosa chinensis L.) cv. Ganganagri Rose

Study on Effect of Biostimulants on Growth, Flowering and Yield of Rose (Rosa chinensis L.) cv. Ganganagri Rose was conducted at Horticulture Farm, Department of Horticulture, Rajasthan College of Agriculture, Udaipur, Rajasthan during October 2024 to March 2025. The result indicated that among the treatment plant sprayed T7 75% RDF + IIHR Arka microbial consortium + Humic acid @ 3 ml/litre was recorded significantly maximum plant height (63.46 cm), number of leaves plant-1 (270.92), plant spread- North to South direction (49.40 cm), plant spread East to West direction (55.10 cm), number of flowering shoot (9.75) and shoot length at first flower bud appearance (26.41 cm). minimum number of days to first flower bud appearance (38.00 days), days to flowering (55.00 days) and highest duration of flowering (114.08 days), flower diameter (6.60 cm), flower weight (5.55 g), total number of flowers plant-1 (116.17), flower yield plant-1 (644.74 g), flower yield plot-1 (2.58 kg), flower yield ha-1 (6.45 t/ha) and shelf life of loose flowers (4.00 days). Thus, combined application of bio-stimulant could be considered as a suitable treatment for enhanced growth, flowering, yield and quality of rose.
