An experiment was conducted to find out the effect of IBA (auxin) concentration and size of cutting on rooting and percent establishment of Jasminum sambac stem cuttings at Horticultural College and Research Institute, Dr. Y.S.R. Horticultural University, Venkataramannagudem. The main objective of the study is to standardize propagation technique for quick and cost effective and efficient mass multiplication of Jasminum sambac cv. “Double Mogra. The 3 node cuttings treated with IBA @ 2000 ppm exhibited significant increase in rooting percentage, root length, root number, root fresh weight, maximum sprout diameter, fresh and dry weight of rooted cuttings. The traits viz., number of days taken for sprouting and propagation cycle was recorded minimum in 3 node cuttings treated with IBA @ 2000 ppm. Whereas 4 node cutting treated with 2000 ppm of IBA and 3 node cutting treated with 3000 ppm of IBA has obtained more number of sprouts and maximum number of leaves per cutting. Among all the treatment combinations, 3 node cutting treated with IBA @ 2000 ppm has shown best results regarding maximum traits. The result revealed that the three node cuttings treated with IBA at 2000 ppm concentration was most effective for obtaining maximum shoot growth, root growth, survival percentage and for its large scale multiplication.
