In this study conducted to find out as to how far different depths of water (D1.0.90), (D2:1.35) and (D 3:1.80) meters given in one growing season to four poplar clones. 1-90/60, 1-72/58, 1-4/64 and 1-4/55 affected their rate of growth, it has been found that the dose of water was insignificant. However, clones between themselves showed different rates of growth; significant at 1%level for dia and height and at 5%for volume; 1-69/55 showing the overall best performance followed by 1-4/64, 1-90/60 showed the poorest growth.
