Abstract: An experiment entitled ‘Effect of different plant growth regulators on the growth, flowering, flower yield and quality of Jasmine (Jasminum sambac) under Prayagraj agro- climatic conditions’ was conducted in Horticulture Research Field, Faculty of Agriculture, Department of Horticulture, Naini Agricultural Institute, SHUATS, Prayagraj during October 2022-May 2023 with an aim to identify the most suitable plant growth regulator under the agro climatic conditions of Prayagraj. There were ten treatment replicated thrice in spacing of 1 m x 1 m randomly. Significant difference in different treatments of tuberose were recorded for all the parameters observed. From the present investigation, it is concluded that among the different treatments, experiment is performed in randomized block design, From the present investigation, it is concluded that among the different treatments, the treatment T1- GA3@ 25ppm was found in superior in terms of plant height (151.33cm), plant spread (115.42 cm2), Leaf area (452.7 m2). However treatment T9- CCC@ 2000ppm performed best in terms of Days to bud initiation (91.33days), 50% flowering (20.78 days), No. of flowers per plant (1989.33), Flower yield per plant (512.98 g), Flower yield per hectare(5.13 t) whereas T7- CCC@ 1000ppm performed best in terms of flower quality in flower Diameter (4.44 cm), Flower weight (0.41 g), Shelf life (2.67 days) and Self life (7.22 days). Treatment-9 had highest benefit cost ratio (2.90).
