 ABSTRACT

The present experiment entitled “Effect of time of air layering and IBA on red jamun (Syzygium samarangense L.) cv. Local” was conducted during the year 2016 at Lalbaugh, Fruit Research Station, Department of Horticulture, Junagadh Agricultural University, Junagadh (Gujarat). The treatments comprised of different time of air layering (M1- 1st May, M2- 1st June, M3- 1st July and M4- 1st August) and different concentration of IBA (C1 - Control, C2- IBA 1000 ppm, C3- IBA 1500 ppm and C4- IBA 2000 ppm). There was sixteen treatments laid out in a Completely Randomized Block Design with factorial concept with three repetition. The observations of air layers were recorded before detachment of layers. In before detachment parameters, air layers prepared on the 1st August exhibited the minimum days of root initiation (18.6), maximum number of primary (7.32) and secondary roots (18.7) per layer at 45 days after layering, primary (9.88 cm) and secondary root length (7.03 cm), fresh weight (0.90 g) and dry weight of roots (0.33 g) per layer, number of shoots per layer (5.8), shoot length (8.3 cm) and rooted layer percentage (79.6). In case of different concentration of IBA, application of IBA 2000 ppm was also recorded minimum days of root initiation (18.1), maximum number of primary (7.88) and secondary roots (20.2) per layer, length of primary (9.88 cm) and secondary roots (7.14 cm), fresh (0.95 g) and dry weight (0.34 g) of roots per layer, number of shoot (6.0) per layer, shoot length (8.6 cm) and rooted percentage (83.2). Whereas, interaction effect of time of air layering and IBA, air layer prepared on 1st August along with IBA @ 2000 ppm resulted in minimum days of root initiation (16.5), maximum number of primary roots (10.87) and secondary roots (26.2) per layer, primary (11.6 cm) and secondary root length (7.59 cm), fresh weight (1.20 g) and dry weight of root (0.50 g) and rooted layer percentage (92.4).

Key words: Month of air layering, IBA, Red jamun, Local, August, ppm.
