Presently, climate change is one of the major ecological problems worldwide. It has important effects on the growth of plants, water usage and movement methods. These effects showed the water use efficiency of plants, communities, and environments, and ultimately, in plants division method pattern, composition of species and environmental system. Water use efficiency of plants assists in the perception and predicting the reactions of plants to climate change globally and the adopting methods. Water use efficiency in vegetation is a manifestation regarding amount of carbon absorbed to the rate of water loss by plants leaves. This research focuses the advantageous effects of water use efficiency on the development behavior of chosen plant. The major aim of that research was to observe the growth response of Tamarix aphylla at normal, mean and excess amount of water consumption. The research was accomplished in the nursery area of the Department of Forestry and Range Management, University of Agriculture Faisalabad. The required plants of the Tamarix aphylla were obtained from the nursery. Four treatment levels together with control level were finalized. The data was tested statistically by utilizing the Randomized Complete Block Design (RCBD). The germinating ability of the plants was noticed against water use efficiency during initial growth periods. Plants were then shifted in containers by applying water at various treatment levels e.g. Daily (T0), four days (T1), eight days (T2), twelve days (T3), and sixteen days (T4) in order to observe the germination ratio and morphologic attributes at various levels of water application. The data exhibited changes in the growth behavior of plans after analysis for the above discussed morphologic attributes. The reaction of each treatment level on the height of the plant was significant. It was almost obvious that the growth response of T. aphylla was quite better by enhancing the water use efficiency.
