Two field experiments were conducted during the hwo growing seasons (2014 and 2015) to investigate the combined effects of three irrigation treatments (I100% = 100%,I85% =85% andI70% = 70% of crop evapotranspiration (ETc)and four thicknesses of mulch layer (TMLo. 3, 6 and 9 cm) under drip irrigation system. The Results showed that the irrigation treatments and thickness of mulch layer on yield and WUE were significant. The greatest values of bean yield(902.4and909.6 kgfeed-1) were obtained under (I100%) in the first and second seasons, respectively, while the lowest ones (698.1 and 692.5 kgfeed-1) were obtained from treatment (I100% )in the first and second seasons, respectively. The average bean yield value of TML9 was increased by 11.5, 30.8 and 40.2 % than those of treatment TML6, 3 and 0. respectively. in the first season. Corresponding values for the second season were 12.3, 32.5 and 43.5 % The greatest values of WUE (0.74 and 0.73 kg m-3) were obtained under I70% compared to I100% (0.67 kg m-3) in the two seasons. respectively.
