The present investigation entitled Impact of IBA and NAA on rooting and its growth parameters of air layers in guava. (Psidium guajava L.). The experiment was conducted at the Nursery area, Department of Horticulture, College of Agriculture, Rajmata Vijyaraje Scindia Krishi Vishwa Vidyalaya, Gwalior (M.P.) during the session 2016 - 2017. The experiment was laid out in Randomized Block Design with 16 treatment combinations consisting of three level of IBA, Io = 0 ppm (Control), I1 = 5,000 ppm IBA, I2 = 10,000 ppm IBA, I3= 15,000 ppm IBA and three level of NAA, N0= o ppm (Control), N1= 5,000 ppm NAA, N2 = 10,000 ppm NAA, N3 = 15,000 ppm NAA. Maximum rooting and its growth parameters were found significantly superior under the treatment of I3 (15,000 ppm IBA) followed by treatment I2 and I1 and for NAA treatments, treatment N3 = 15,000ppm NAA was observed significantly higher followed by N2 = 10,000 ppm NAA in all the parameters. Interaction of I3N3 was also find out better than all the treatments, callus formation, number of primary roots/ air-layer, length of primary roots, diameter of primary roots, number of secondary roots / layer, length of secondary roots, diameter of secondary roots, fresh weight of roots/ air-layer, success in rooting percentage.
