Improvement on rooting quality of Jatropha curcas using indole butyric acid (IBA).

The effects of indole-3-butyric acid (IBA) concentrations and three types of cutting (softwood,semi hardwood and hardwood) on root performance of Jatropha curcas L. cuttings were investigated. Two experiments were conducted where in experiment 1, conducted on July 2007, the hardwood cutting gave the...
