Two field experiments were conducted at the experimental station of Desert Research Center (D.R.C.) at EL-Kharga Oasis, New Valley Governorate, Egypt, during 2022/ 2023 and 2023/ 2024 growing seasons, to study the effect of some rates of bentonite, biochar and types of compost on productivity of faba bean (Vicia faba L.) and soil properties under sandy soil condition at New Valley. The results recommend to applying a bentonite at a rate of 4 ton fed.^-1, and vegetable compost at a constant rate of 10 m³ fed.^-1 and biochar at a rate of 1000 kg fed.^-1 to improvement of soil properties and maximum faba bean productivity are growing in sandy soils. Whereas, The percentage of increase in plant height was 24.69 %, number of pods plant^-1 was 82.78 %, seed yield was 59.09 %, weight of 100 seeds was 57.78 %, protein yield was 31.25 %, WUE was 92.67 %, porosity was 7.94 %, soil WHC was 19.58 and organic matter was 64.00 % when using these rates of the three studied factors referred to, as compared of the control treatment (without addition).
