Author(s): C Rajamanickam and TN Balamohan
Abstract: Effect of Indole Butyric Acid (IBA) on rooting of pomegranate semi hardwood cuttings cv. Bhagwa was carried out at College Orchard, Department of Horticulture, Agricultural College and Research Institute, Madurai during 2018 – 19 with the aim to identify the best IBA concentration suitable for pomegranate semi hardwood cutting. Six levels of IBA viz., 0 (control), 500, 1000, 1500, 2000 and 2500 ppm concentrations were prepared and treated with semi hardwood cuttings as quick dip method. Pomegranate var. Bhagwa used for this study. These cuttings were planted in polybags and were kept under mist chamber for sprouting. The study was laid out in a Completely Randomized Block Design (CRD) with six treatments and five replications. Observations on success per cen (%), number of sprouts, days taken for sprouting (days), number of leaves, plant height (cm), shoot length (cm), root length (cm), fresh root weight (g) and dry root weight (g) were recorded and analysed statistically. The results revealed that cuttings treated with IBA of 2500 ppm (T6) recorded the highest values of all the traits viz., success per cent (75.50%), least number of days for sprouting (9.79 days), number of sprouts per cuttings (4.20), number of leaves (43.52), plant height (49.25 cm), shoot length (31.6 cm), root length (3.24 cm), fresh root weight (2.1 g) and dry root weight (1.85 g) followed by T5 (2000 ppm of IBA). Control (T1) (without IBA treatment) observed the lowest values of the traits like success per cent of cuttings (20.80%), longest days for sprouting (12.50 days), number of sprouts per cuttings (1.40), number of leaves (22.20), plant height (28.25 cm), shoot length (18.80 cm), root length (0.50 cm), fresh root weight (0.79 g) and dry root weight (0.68 g). From the conclusion of the present study, IBA treated with 2500 ppm (T6) semi hard wood cuttings was the best method for mass multiplication of pomegranate.
