The study was conducted on “Effect of Different Growth Regulators and potting media on morphological and biomass traits on G48 clone of poplar†in the forest Nursery and Research Centre (School of Forestry and Environment) of Sam Higginbottom Institute of Agriculture Technology and Sciences, Allahabad. The cuttings were obtained from the forest Nursery, School of Forestry and Environment with 15 cm length and without any branches and flowers. The experiment was laid out in Completely Randomized Design (CRD). There were six treatments including control replicated four times in which several growth regulator control (distilled water), IBA(100 ppm), IAA (100 ppm), NAA (100 ppm), GA3 (100 ppm), 2,4-D (100 ppm) were used with 10 cuttings per replication. Among the different treatments the most effective growth regulator was T1 (IBA 100 ppm) which gave better results with diameter, leaf area. number of root, shoot length, root length, shoot fresh weight, root fresh weight, root dry weight, total biomass compared to control and other treatments, so it can be recommended that IBA as a most effective growth regulator among the all treatments.. In potting media there were seven treatments with three replications and the combinations were control Soil: Soil: FYM: Sand 1:1:1, Soil: FYM: Neem cake 1:1:1, Soil: FYM: Vermicompost 1:1:1, Neem cake: sand: Vermicompost 1:1:1, Neem Cake: Soil: Vermicompost 1:1:1, Neem cake: FYM: Vermicompost 1:1:1. Among all potting media combinations most effective treatment was T1 (Soil: Sand: FYM 1:1:1) which shows better results in sprouts/cutting, survival percentage, diameter, leaf area, shoot dry weight, root fresh weight, compared to control or other treatments so it can be recommended that the combination of ( Soil: Sand: FYM 1:1:1) as effective treatment for the growth of poplar cuttings. Hence it has been concluded that IBA with 100 ppm and combination of Soil: Sand: FYM (1:1:1) can be recommended to obtain best growth and development for poplar cuttings.
