The effects of indole-3-butyric acid (IBA) concentrations and three growth conditions of cutting (open area, under partial shade and under low cost polyhouse) on root performance of Citrus aurantifolia (Swingle) were investigated during March 2007 to Oct 2009. The cuttings treated with IBA @ 500 ppm, performed the best, as far as the success rate is concerned while, planting the cuttings in open area was effective in increasing the success rate of the cuttings. The vegetative growth was recorded to be the highest in the cuttings planted under polyhouse conditions. The greatest sprouted bud (68.50%) was obtained in 500 ppm followed by 1000 ppm (53.67%), while lowest (36.55%) occurred in control. Therefore it concludes that 500 ppm of IBA with open area conditions is recommended for the vegetative propagation through semi-hardwood cuttings of kagzi-lime.
