Abstract: An experiment on “comparative evaluation of hardwood and semihardwood cutting with different rooting hormone in (Bougainvillea buttiana) cv.Mahara” using three different rooting hormones (IAA, IBA and NAA) was conducted under shade net, at Department of horticulture research field of Sam Higginbottom University of Agriculture, Technology and Sciences, from the month of April to July 2019. The experiment was laid out in a Completely Randomized Design (CRD) with three replicates. Data were collected on Days to first Sprout, no of vegetative buds sprouted/cutting, sprouting percentage number of leaves /cutting, number of shoots / cutting, plant height, stem girth, length of longest shoot/ cutting, number of roots / cutting, length of longest root/cutting, mortality rate. The results showed that hardwood cuttings were found to give significantly better results than semihardwood cuttings treated with different rooting hormones (12hrs). A long dip (12hrs) treatment of IBA1500ppm for hardwood cuttings showed significantly better results than control and all the other treatments with respect to minimum Days to first Sprout (15.723), maximum no of vegetative buds sprouted /cutting (4.000), maximum sprouting percentage(60.000%), number of leaves /cutting(52.333), number of shoots/cutting((3.667), length of longest shoot/ cutting (42.270cm), plant height (45.603cm), maximum stem girth (1.227cm), number of roots/cutting (26.943), length of longest root/ cutting (19.267cm), minimum mortality rate (40.000%) whereas in case of semi hardwood cutting the long dip (12hrs) treatment with IBA1500ppm cuttings was significantly better than control and all the other treatments with respect to minimum days to first sprout (17.167), maximum sprouting percentage (40.000%), maximum number of leaves /cutting (31.500), maximum length of longest shoot (31.030cm), maximum plant height (33.697cm), maximum Stem girth (0.827 cm) maximum number of roots (22.833), longest root(17.500cm), minimum mortality rate (60.000%) whereas maximum vegetative buds sprouted (3.000) was obtained in cuttings treated with NAA(1500ppm), maximum number of shoots per cutting (3.000) was obtained in cuttings treated with IAA(1000ppm), IAA(1500ppm) and IBA(500ppm).
