Abstract: The present investigation entitled, “Effect of IBA concentrations on rooting and growth of Ulmus wallichiana Planchon stem cuttings under Temperate conditions of Kashmir” was carried out at Faculty of Forestry SKUAST-K Benehama during the year 2018-19. In this research, in order to study the effect of different concentrations of IBA on rooting and survival of Ulmus wallichiana cuttings, a study was conducted in a randomized complete block design with four replications. Treatments consisted of five levels of hormones: 0 (control), 500ppm, 1000ppm, 1500ppm, 2000 ppm and 2500ppm of IBA. Results showed that highest rooting (15.00% and 5.37%) root length 10.62cm and 8.62cm were recorded for IBA concentrations of 2000ppm in the hardwood and softwood cuttings respectively. The maximum mean length of shoot 8.12cm and 8.26cm were achieved in concentration of 2000ppm IBA in hardwood and softwood cuttings respectively. Further percentage 10.50% and 4.50% survival was recorded in hardwood and softwood cuttings at 2000ppm IBA treatments. Moreover, greatest sprouting 50.25% in hardwood and 9.75% in softwood was obtained in concentration of 2000ppm IBA, under open field conditions.
