 ABSTRACT

An experiment was conducted at the Orchard Section, Horticultural Research Centre and Department of Horticulture, Chauras Campus, School of Agriculture and Allied Science, HNB Garhwal University (A Central University), Srinagar Garhwal, Uttarakhand, India during the rainy season of the year 2016 to evaluate the effect of different time of air layering, IBA concentrations and growing media on the rooting behaviour of Pant Prabhat Guava (Psidium guajava L.). Experiment was laid out in Factorial Randomized Block Design having forty eight treatment combinations of air-layering time (15th June, 30th June, 15th July and 30th July ), IBA concentrations (1500 ppm, 3000 ppm, 4500 ppm and Control) and growing media (Sphagnum  moss, Coco peat and Sphagnum moss+ Coco peat). The treatments were replicated thrice. The response of Pant Prabhat guava to the treatments was evaluated on the basis of rooting attributes those are best under T3C3M1 treatment viz., minimum days taken to root appearance (26.11days), maximum rooting percentage (100%), maximum number of roots per layer (26.22), maximum length of longest root per layer (16.07cm), maximum diameter of thickest root per layer (1.94mm) and maximum percentage of layers showing secondary roots (80%). On the basis of results obtained in the present investigation, it can be concluded that air-layering performed during 15th July, treated with 4500ppm IBA concentration and use of sphagnum moss as growing media have been found significantly superior on all other treatments under subtropical condition of Garhwal Himalaya.

Key words: Air-layering, IBA, Coco peat, Sphagnum moss, Percentage.
