Description Calliandra calothyrsus Meissn. is a leguminous fodder tree that has recently become the subject of intensive study and cultivation due to its protein rich foliage and other uses. Calliandra is usually propagated through seeds, however the seed set is very poor under humid tropical conditions. Calliandra cannot be easily multiplied by planting stakes directly in the ground, and detailed studies on vegetative propagation are absent in this species. Present investigation was carried out at College of Forestry, Vellanikkara to standardize a protocol for large scale planting stock production of fodder calliandra from coppice cuttings, by assessing the influence of types of cuttings (softwood/semi-hardwood), type and concentration of growth regulators like IBA( Indole-3-butyric acid ) and NAA( Naphthaleneacetic acid ) (0, 50, 100, 200 and 250 mg l-1); and the influence of season (rainy and summer) on the root and shoot development in vegetatively propagated calliandra. Two separate trials were carried out in both seasons with 19 treatments for each trial laid out in CRD (Completely Randomized Design) design, and one absolute control viz., calliandra planting stock raised from seeds, for relative comparison.  Results indicate that calliandra can be vegetatively propagated from soft wood coppice cuttings by overnight soaking with 50 ppm of NAA and using vermiculite as rooting medium under controlled conditions of mist chamber, preferably during summer season. 50 ppm IBA was found to be the second-best treatment. The shoot and root parameters of vegetatively propagated calliandra planting stock was found to be on par with that of calliandra seedlings. Non-mist propagation method and soil based rooting medium were found to be unsuccessful for vegetative propagation of calliandra in humid tropical condition of South India.
