Abstract
A pot experiment was conducted to evaluate the morphochemical response of chaksu (Cassia absus L.) to different levels of IAA. Different concentrations of IAA were applied thirty days after germination. IAA was applied as a foliar spray and experiment was laid out in completely randomized design (CRD). Indole acetic acid significantly increased all the growth parameters as shoot and root lengths, shoot fresh and dry weights, number of leaves and yield per plant in chaksu. Similarly, NPK concentrations were increased with IAA. It is concluded that IAA was useful for the increase of growth and yield of chaksu. IAA concentrations of 50-100 mg/L showed significant effect on plant growth and yield as compared to control.
