the experiment was procedures through two winter consecutive seasons of 2020/2021 and 2021/2022, at a private plantation in El- Baharia Oasis area, Giza Governorate, Egypt, to compared the effect of LBI and SI irrigation systems at IR=100, 85, 70 and 55% calculated based on crop evapotranspiration and three PHR= 0, 4 and 8 kg fed-1, on crop quality parameters, MSY, ETa, WUE and IWUE for winter faba bean (Vicia faba L.) . The results indicated that the marketable seeds yield and quality parameters except SCC % and SPC % of winter faba bean crop gave the highest values under LBI, IR=100% and PHR = 6 kg fed-1 treatment for both seasons while, the maximum values of winter faba bean crop WUE and IWUE were 1.89 and 1.52 kg m-3; 1.96 and 1.55 kg m-3 for both seasons, respectively, under LBI, IR=70% and HAR = 6 kg fed-1 treatment. This study indicated that the farming of winter faba bean crop under LBI, IR=70% and HAR = 6 kg fed-1 treatment can probably conserve about 30% of the applied irrigation water and raise marketable seeds yield of winter faba bean crop about 36% as average for both seasons compared with that under control treatment (i.e. SI, IR=100% and PHR = 0 kg fed-1).
