ABSTRACT
The current study examined how different treatments of IBA affected the rooting of hardwood cuttings of
the Prabhat variety of peach. During the first week of January, 19-21 cm cuttings with a diameter of 0.9-
1.3 cm with 4-5 buds were taken from dormant cuttings of 7-10 year old peach trees. The basal cuttings
section was immersed in various dosages of IBA (800, 1600, 2400, 3600, 4500 ppm and control (no IBA
treatment). These cuttings were treated for 1-2 min before planting in open fields. All the cuttings were
grown using the standard nursery raising procedures. It was revealed that hardwood cuttings treatment
with 2400 ppm indole-3-butyric acid for 1 to 2 min took less time to sprout with a higher percentage of
sprouting, survival, average, number of branches, root number, root weight, root girth, root girth length,
plant height, number of leaves and plant girth. Therefore, this level of IBA may be recommended for the
economic productivity of peach cultivation.
