Laboratory and field experiments were designed to investigate the influence of moringa leaves extract concentrations as seed soaking and foliar treatments on seed germination characters, field emergence, growth and yield as well as its attributes of faba bean (cv Sakha 1). Moringa leaves extract concentrations under study for both seed soaking and foliar treatments were (0, 5, 10 and 15 g/l). The results could be summarized as follows: Soaking faba bean seed in moringa leaves extract, generally recorded significant effect on all germination and seedling characters except germination (%). Soaking faba bean seed in moringa leaves extract (10 g/l) gave the highest values of field emergence (%), emergence index and seedling characters compared with soaking in distilled water. Moringa leaves extract as a seed soaking treatment had significant effect only on branch/m² and seed yield (kg/fad). No significant differences of all characters under study were obtained between soaking seed in distilled water and soaking in moringa leaves extract concentration (5g/l). Application moringa leaves extract (10 g/l) as a foliar in the field, recorded the highest values of growth and yield characters compared with control. It could be concluded that seed soaking and foliar application of  moringa leaves extract concentration (10 g/l) was a successful way to improve field emergence and seed yield of faba bean (cv. Sakha 1).
