Performance of Air-layering under Various Concentration Level of Auxin in Azadirachta indica (A. Juss)

Present study was carried out on mature trees at Dr. Panjabrao Deshmukh Krishi Vidyapeeth, Akola campus, to find out the response of auxins on air layering on Azadirachta indica. The air layering was done from first week to second week of August, 2013. Auxins, IAA, IBA and NAA were used at three concentration viz. 1000 ppm, 2000 ppm and 3000 ppm with one control, replicated three replications. IBA at 3000 ppm concentration were significantly superior to other treatments of auxins. From the present investigation it can also be concluded that the air layering is a viable method for mass propagation of Azadirachta indica.
