A pot experiment was conducted on Plumbago zeylanica L. (Chitrak) under controlled water stress environment in greenhouse during the kharif season. The experiment was laid out in completely randomized design with five treatments of different water stress levels i.e. control, 20%, 40%, 60% and 80% and four replications. Out of five stress levels, 80% water stress has influenced root length, dry herbage, plumbagin, potassium and proline content. In control conditions the plant height, number of leaf, total leaf area, stomatal conductance, transpiration rate, photosynthesis, CO2 utilization, H2O utilization and chlorophyll were found to be maximum. The impact of water stress on plumbagin content has shown increase trend with respect to different water stress levels that is maximum at 80 % and minimum at control.
