Differential Effect of Different Methods of Applying Paclobutrazol on Calendula (Calendula officinalis L.) in Prayagraj Climatic Condition

A field experiment was carried out to investigate the effect of different method applying Paclobutrazol on plant growth and flower yield Calendula (Calendula officinalis L.) cv. Bon Bon, during November 2022 February 2023 at Floriculture Research Field, Department Horticulture, Sam Higginbottom University Agriculture Technology Sciences, Pryagraj (U.P.). Different methods viz., T0 No Treatment, T1 Paclobutrazol@ 50 ppm as Foliar application, T2 100 T3 150 T4 200 T5 Soil drenching, T6 T7 drenching T8 applied assess vegetative, floral characteristics . The laid in complete randomised block design with nine treatments three replications. result for showed significant difference various treatment soil application a paclobutrazol well foliar application. In general paclobutrazol@ improved parameters suggest its efficacy comparison plants that had other applied, plant's height is reduced, making it smaller more dwarflike, number lateral branches increased, increasing yield. When compared found be effective because roots absorb substance. This are less capable absorbing substance higher rates evapotranspiration
