Many recent studies interest on biochar application as the soil amendment and water management system due to its potential to soil nutrient retention, and increase water application efficiency "WAE" and sweet pepper productivity. Therefore, this study aims to investigate the effect of biochar and its combined effect on water application efficiency, water productivity, nitrogen concentration, and sweet pepper yield under sandy soil cultivation. Two field experiments were carried out during growing seasons 2017 and 2018 to study the effect of interaction of adding biochar and nitrogen fertilization stress (N) on water application efficiency, yield of sweet pepper (YSP), water productivity (WP) and vitamin C of sweet pepper. Three application rates of biochar (zero (control), 3.5, 7 and 10.5 ton ha-1) were used under three levels from nitrogen fertilization stress (100%, 80% and 60% N) under drip irrigation methods. The results revealed that increasing the application of biochar materials with 100% N fertilization treatments had a positive impact on WAE, YSP, WP and vitamin C of sweet pepper. The most effective level in this regard when plant were treated and adding 10.5 ton ha-1 of biochar as well as when plant were irrigated with 100 % and adding 10.5 ton ha-1 of biochar in both seasons of 2017 and 2018 respectively. A similar direction was observed with vitamin C content of sweet pepper compared with control treatments and irrigation with 80 % of without adding biochar. In addition, water productivity parameter was significantly improved by application of adding biochar with N-fertilization. In conclusion the biochar application was recommended for a potential soil amendment as its significantly increased yield, water productivity and vitamin C.
