Online Published on 12 February, 2024. Abstract The present investigation entitled was conducted during November 2019 to January 2020 in the shade net house of Department of Floriculture and Landscape Architecture, K. N. K. College of Horticulture, Mandsaur, Rajmata Vijayaraje Scindia Krishi Vishwa Vidyalaya, Gwalior (M.P.). The experiment was laid out in a Completely Randomized Design (CRD) with eleven treatments and three replications. Five concentrations of each plant growth regulators namely IAA (1500, 2000, 2500, 3000 and 3500 ppm) and IBA (1500, 2000, 2500, 3000 and 3500 ppm) were considered as each treatment viz. IAA at 1500 ppm (T1), IAA at 2000 ppm (T2), IAA at 2500 ppm (T3), IAA at 3000 ppm (T4), IAA at 3500 ppm (T5), IBA at 1500 ppm (T6), IBA at 2000 ppm (T7), IBA at 2500 ppm (T8), IBA at 3000 ppm (T9), IBA at 3500 ppm (T10), Control (T11). The cuttings were treated according to the treatments and planted on polybags under shade net house. The results revealed that IBA @ 3000 ppm (T9) had significant effect on shoot and root growth of nerium cutting and recorded the maximum value of various attributes of shoot and root parameters like days taken to sprouting (11.33 days), number of shoots per cutting (4.60), shoot length (3.99 cm), fresh weight of shoot per cutting (2.573 g), dry weight of shoot per cutting (0.743 g), number of roots per cutting (34.53), root length (10.85 cm), fresh weight of root per cutting (0.452 g), dry weight of root per cutting (0.097 g) and survival percentage of rooting (78.88%) recorded the maximum values.
