A study of different concentration of IBA and NAA on rooting per cent of guawa (Psidium guajava L.), air layering

Abstract

The present investigation entitled “A study of different concentration of IBA and NAA on rooting per cent of guawa (Psidium guajava L.), air layering.” was conducted at the Horticulture farm Nursery, Department of Horticulture, College of Agriculture, Rajmata Vijya Raje 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 NAA, N0= o ppm (Control), N1= 5,000 ppm NAA, N2 = 10,000 ppm NAA, N3 = 15,000 ppm NAA. Maximum rooting percent was found significantly under I3 (15,000 ppm IBA) treatment followed by I2 and I1 including control and for NAA treatments N3 = 15,000ppm NAA was observed significantly higher followed by N2 = 10,000 ppm.
