Bush pepper is a miniature black pepper (Piper nigrum L.) plant grown in the form of a bush as potted plant with decorative and economic value, raised from lateral branches (plagiotrops) of yielding vines. Growth hormones and plant growth promoting rhizo-microorganisms were evaluated for their effects on rooting of plagiotropic cuttings of black pepper. The fruiting branches of black pepper variety Panniyur 1 were employed for the study. There were totally nineteen treatments that included PGPRs viz. Azospirillum lipoferum and Pseudomonas fleuroscens and plant growth hormones viz. IBA, NAA and 2, 4D at different concentrations. The treatment T8 (IBA 1000 ppm) proved to be the best for rooting by recording maximum values for percentage rooting (65.30), fresh weight (1.10 g),dry weight of root (0.53 g), per cent survival (54.04) followed by IBA 1250 ppm. The treatment also recorded maximum net income (Rs. 11492.00 / 1000 cuttings) and highest benefit cost ratio (1: 3.43).
