Abstract: The present research was conducted at ZAHRS, Mudigere, Karnataka to know the optimum concentration of growth regulators and different types of media to induce rooting in black pepper cuttings under greenhouse conditions. The study revealed that, among the different growth regulator formulations the IBA 1000 ppm formulation helped in better induction of rooting by over 70 per cent as against 43. 33 per cent in the control. However, the cuttings treated with proven growth regulator concentration (IBA 1000 ppm) was raised in the media comprising soil + sand + FYM + vermin compost (1:1:1:1 v/v) significantly increased the different shoot parameters of cuttings such as, days to sprout, number of leaves per cutting, length of shoot, percentage of sprouting, fresh and dry weight and root parameters such as, minimum days to rooting, higher percentage of rooting, higher number of primary roots, maximum fresh and dry weight of roots. Hence the study proved that, the cuttings treated with growth regulator IBA 1000 ppm concentration and raised in rooting media of soil + sand + FYM + vermin compost (1:1:1:1 v/v) were proven best for propagating Black pepper cuttings.
