Khirk (Celtis australis Linn.) is an important multipurpose tree species, which has a great potential in Social/Agroforestry practices in the North-Western Himalaya. Since seed regeneration is a problem, rooting cutting is one of the options for carrying mass multiplication programme in this valuable species. Experiments were therefore conducted to ascertain the effects of donor stage, pre-conditioning (girdling), cutting portion and auxin treatments on rooting behaviour of Khirk. Auxin IBA in 0.2-1.0% concentration mixed with or without other chemicals (5% sucrose + 5% captan) was used for the treatment of cuttings. The cuttings taken in rainy season (July) and from tree donors performed remarkably better than those taken in spring and pole/sapling stage, respectively. The sub-apical and the girdled cuttings resulted in significantly superior rooting and root quality as compared to the apical and non girdled ones. Further, interaction effect revealed a maximum 90 per cent rooting when girdled cuttings from sub-apical portion were treated with 0.4% IBA-talc formulation in monsoon season.
