Abstract:
This research was carried out at a field during 2021-2022 season in Talkalakh region in Western Area-Homs to study the effect of spraying with seaweeds extract and plant density on some growth and productivity traits of faba bean crop (var. Kubrusy). Three concentrations of seaweeds extract were used (1, 1.5, 2) g/l in addition to 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 seaweeds extract (2)g/l caused a significant increase in: plant height (74.72) cm, number of branches/plant (4.51), pod length (11.83) cm, number of pods (11.08) pod/plant, weight of dry seeds (33.20) g/plant and seed yield (5747.22) kg/ha. Increasing plant density to (25) plant/m2 caused an increase in: plant height (74.76) cm, the first pod height (18.25) cm and seed yield (5260.83) kg/ha, while it caused a significant decrease in: number of branches/plant (2.93), number of pods (6.47) pod/plant, weight of dry seeds (21.04) g/plant. Spraying (2) g/l of seaweeds extract and planting (25) plants/m2 gave the highest seed yield (6859.17) kg/ha.
Key words: Faba bean, seaweeds extract, plant density, seed yield.
