Pearl millet is better adapted to hot and semi-arid conditions than most other major cereals. The objective of this study was compare the deep water uptake ability use efficiency (WUE) pearl among species. First, WUE six species evaluated in pots under waterlogging, well-watered (control), drought conditions. Secondly, from soil layers by barnyard millet, which showed highest waterlogging tolerance, respectively, compared long tubes consisted three parts (two loose separated a hardpan Vaseline layer). Soil moisture adjusted upper (topsoil) layer, while lower (deep) layer always kept wet. significantly reduced all but not drought. ratio control condition indicated that had lowest resistances conditions, stable both deuterium concentration xylem sap water, relative layers, roots were increased topsoil layers. In conclusion, resistance explained higher as another drought-resistant
