The greenhouse experiment was conducted to evaluate growth response and proline content of wild elephant grass (Pennisetum polystachion) to NPK fertilization and water stress. A factorial experiment in the base of completely randomized was performed design with 2 factors, replicated 3 time. Factors were (i) NPK fertilizer (0, 50, 100 and 150 kg-ha), (ii) water stress (80, 60 and 40% of field capacity). Observed parameters were plant height, number of tiller, number of leaves, leaf area, shoot dry weight, root dry weight, and root to shoot ratio and proline content of wild elephant grass. Results showed that NPK fertilizer significant (P>0.05) increased plant height, number of tiller, number of leaves, leaf area and root dry weight, but did not affect (P<0.05) on shoot weight, root to shoot ratio and proline content. Water stress significant (P<0.05) root weight and proline content, but did not affect (P>0.05) plant height, number of tiller, number of leaves, leaf area, shoot weight and root to shoot ratio. No interaction (P>0.05) between NPK fertilization and water stress treatments on all observed parameter. The study showed that wild elephant grass was response to NPK fertilizer and resistance to water stress condition.
