ABSTRACT
The application of various plant growth regulators hormones like auxins in form of Indole Butyric Acid (IBA) improve root development in asexual propagation of olive crop. In order to investigate the “Comparative effect of different doses of Indole Butyric Acid (IBA) on propagation success of two olive varieties”, during the year 2021, an experiment was undertaken at PARC-National Tea and High Value Crops Research Institute Shinkiari, Mansehra, Pakistan. The trial was conducted using Randomized Complete Block Design (RCBD) with split plot arrangements with three replications. It was consisted of varieties i.e., Arbequina and Megaran which were allotted to the main plot and different concentrations of IBA i.e., IBA @ (0, 3000, 3500 and 4000 ppm) which was assigned to the sub plot. Significant variation among characters were noted for different treatemtns. In case of varieties, maximum sprouting percentage (4.95%), thickness of sprouted cutting (6.04 mm), shoots length (38.83 cm), number of secondary roots (8.58) was recorded from cuttings which were taken from variety Megaran. Highest number of shoots per cutting (2.13), root length (15.40 cm) was obtained from cuttings which were taken from variety Arbequina. In treatment IBA, more number of secondary roots (8.93), shoot length (51.94 cm) and thickness of sprouted cutting (7.27) was recorded from cutting which were treated with IBA @ 3000 ppm. Highest root length (19.42 cm), number of shoots per cutting (2.40) was recorded from cutting which were treated with IBA @ 3500 ppm. Maximum sprouting Percentage (5.95 %) was noted from cutting which were treated with IBA @ 4000 ppm. The present study reveals that IBA @ 3000 ppm in combination with variety Megaran gives promising results. For optimum outcomes, it is recommended that olive cuttings should be treated with IBA @ 3000 ppm.
