Effect of IBA Concentrations, Time and Rooting Media on the Rooting Behaviour in Guava (Psidium guajava L.) Air Layering, under Hadoti Region

Abstract

The present investigation is entitled “Effect of IBA concentrations, time & rooting media on the rooting behaviour in guava (Psidium guajava L.) Air layering, under Hadoti region”. The experiment was conducted at the Department of Horticulture, School of Agriculture Science, Career Point University Kota Rajasthan during the session 2018-2019. The experiment was laid out in factorial Randomized Block Design with four levels of IBA concentrations (C1 (3000ppm), C2 (4000ppm), C3 (6000ppm), C0 (Control), three different rooting media M1 (Moss grass), M2 (Coco-peat), M3 (Moss grass+ Coco-peat) and two months air layering (T1 (June) and T2 (July). The maximum number of primary roots per air-layer, length of primary roots per air-layer, diameter of primary roots, number of secondary roots per air-layer, length of secondary roots, diameter of secondary roots, average dry weight of roots per air-layer, rooting percentage and survival percentage was observed under C3M3T2 (6000 ppm IBA + Moss grass + Coco peat + July) treatments.
