A FIELD experiment with three replications was conducted on drip ……irrigated sandy soil during two successive summer seasons (2013 and 2014) at Agricultural Research Station farm in Ismailia Governorate, Egypt. Peanut was cultivated as an indicator crop to evaluate the effect of irrigation stress and different rates of hydrogel polyvinylalcohol (PVA) as a soil amendment on peanut crop yield and macronutrients total contents along with some plant water relationships. The main plot was three irrigation treatments, i.e. 25%, 50% and 75% of the available soil moisture (ASMD) as well as the sub main plots were four rates of poly vinylalcohol (PVA) soil amendment (zero %, 0.05% , 0.1% and 0.2%) were added before the soil tillage. Data indicated that water consumptive use increased as soil moisture depleted decreased. The lowest water consumptive use 692.72 mm and 700.76 mm at the first and second season, respectively were obtained under dry conditions (severe soil moisture stress, irrigated at 75% ASMD). Whereas, the highest values of water use 1293 mm and 1318 mm at the first and second season, respectively were attained under soil moisture level (irrigation when 25% of ASMD is depleted). Also, the lowest and highest averages values of actual evapotranspiration were recorded by adding 0.2 and zero% of PVA, respectively. In addition, it could be used FAO modified Blaney-Criddle method for calculation of seasonal peanut crop ETc in Ismailia condition, because the results obtained by this method are close to results obtained when irrigation achieved at 50% ASMD. Moreover, peanut yield (straw and seeds) along with total content of macronutrients (N, P and K) increased significantly under the irrigation treatment of 25% ASMD in presence of 0.20% PVA soil amendment comparing with other treatments. Finally, results showed that water use efficiency (WUE) was significant in both seasons. The values of WUE could be increased either by increasing crop yield or decreasing evapotranspiration. The highest values of WUE were gained using irrigation level of 50% ASMD irrigation treatment followed by 25 and 75% ASMD and the differences were significant. The relationship between water use efficiency (WUE) and seeds yield along with concentration of PVA was significantly positive linear correlation in successive two cultivated seasons.
