The present investigation was carried out at commercial fruit unit .the objective to study the effect of IBA concentration and time of air layering on rooting of guava air layer and to find out the suitable concentration of IBA and time for higher success in guava air layers. The experimental was laid out in factorial Randomized Block design (FRBD) with two factor ,IBA concentration with five levels control (I0) 2500 ppm (I1) 5000 ppm (I2) 7500 ppm (I3)and 10000 ppm (I4) time of air layering ,15 July ,15 august and 15 September ,which were replicated for times .The result of the investigation indicated that amongst different concentration of IBA, the guava air layer treated with 10,000 ppm observed the minimum days required layer treated with 10,000 ppm observed the minimum days required for root initiation, maximum percentage of rooted layer, number of primary root ,number of secondary root ,length of primary root ,lengths of secondary root ,fresh weight of roots ,dry weight of roots ,root volume ,maximum number of sprouts ,length of sprout ,height of rooted layer ,number of leaves ,average leaf area ,fresh weight of shoots ,dry weight of shoot ,fresh weight of roots ,dry weight of roots and shoots fresh weight of roots ,dry weight of roots and survival percentage followed by IBA 7500 ppm . In respect to time of air layering, August month (M2) was recorded maximum percentage of rooted layer, number of primary roots, number of secondary roots, length of primary and secondary roots fresh weight of roots dry weight of roots and survival percentage followed by July month.The combined effect of different IBA concentration and time of air layering indicates that, combination IBA 10,000 ppm +August month was observed significantly maximum value for percentage of rooted air layer ,number of primary and secondary roots ,length of primary root ,fresh and dry weight of roots and survival percentage followed by the treatment combination IBA 10000 ppm +July month .
