This research was carried out at Barry Al- Garby village, Al Salameah region during 2017/2018 season to study the effect of spraying with yeast suspension and plant density on some growth and productivity traits of faba bean crop (var. Kubrusy). Three concentrations of yeast solution were used (2, 4 and 6) g/l in addition the control treatment. Three densities were studied (12.5, 16.7 and 25 plants/m2). A split plot design with three replications was used. Spraying with yeast suspension (6) g/l caused a significant increase in plant height (75.21) cm, number of branches/plant (3.65), pod length (11.33) cm, number of pods (11.18) pod/plant, weight of dry seeds (33.37) g/plant and seed yield (0.58) kg/m2. Increasing plant density to (25) plant/m2 caused an increase in plant height (75.2) cm, the first pod height (18.57) cm and seed yield (0.53) kg/m2, while it caused a significant decrease in number of branches/plant (2.97), number of pods(6.5) pod/plant , weight of dry seeds (21.12) g/plant. Spraying (6) g/l of yeast and planting (25) plants/m2 gave the highest seed yield (0.69) kg/m2.
