Response of different media and IBA on shoot sprouting and growth of hardwood cutting in pomegranate (Punica granatum L.) cv. Bhagwa

Abstract

The field experiment entitled “Response of different media and IBA on rooting and survival of hardwood cutting in pomegranate (Punica granatum L.) cv. Bhagwa” was carried out at Fruit Research Station, Madhadi Baug Farm, Department of Horticulture, College of Agriculture, Junagadh Agricultural University, Junagadh during 2015-16. The experiment was laid out in a Completely Randomized Design with Factorial concept by three repetitions. The treatment consist of five level of different media M1 (soil), M2 [soil + FYM (1:1)], M3 [soil + perlite (1:1)], M4 [soil + sand + FYM (1:1:1)] and M5 [soil + FYM + perlite (1:1:1)] and three level of IBA concentration I1 (IBA 2000 ppm), I2 (IBA 2500 ppm) and I3 (IBA 3000 ppm). The mixture of media influenced on minimum days to shoot sprouting (8.78 days), maximum sprouting percentage (88.90%) at 30 DAP, number of leaves per main shoot (25.84, 57.68 and 90.40), number of shoots per cutting (6.32, 6.87 and 7.17), length of main shoot per cutting (23.71 cm, 33.47 cm and 51.56 cm), thickness of main shoot per cutting (1.18 mm, 2.35 mm and 3.38 mm). Among the factor IBA, I3 (IBA 3000 ppm) recorded significantly the minimum days to shoot sprouting (7.82 days), maximum sprouting percentage (89.77%) at 30 DAP, number of leaves per main shoot (33.34, 63.73 and 101.05), number of shoots per cutting (5.68, 6.60 and 6.83), length of main shoot per cutting (20.94 cm, 29.08 cm and 45.82 cm), thickness of main shoot per cutting (1.12 mm, 2.24 mm and 3.42 mm) at 30, 60 and 90 DAP, respectively. The interaction effect between the media and IBA were found significant in parameters like; maximum sprouting percentage (95.96%) at 30 DAP, maximum number of leaves per main shoot (39.53, 70.29 and 108.20), length of main shoot per cutting (26.73 cm, 37.40 cm and 56.11 cm) at 30, 60 and 90 DAP, respectively. The interaction effect between the different media and IBA were found non significant in parameters like; days to shoot sprouting, thickness of main shoots per cutting and number of shoots per cutting.
