The impact of insect pollinators on yield and yield components of faba bean (viciafaba l.)‎

الملخص EN

Faba bean (Vicia faba L) is relatively an important leguminous food crop in Middle East Inadequate pollination is considered a major constraint to the potential yield of taba bean.

Three pollination treatments TO (Open pollination by all insects including honeybees), TJ (Cages pollination by honeybees only) and T2 (Cages pollination without honeybees and other insects) were applied on two cultivars of taba beans during two consecutive years to evaluate the effect of insect pollinators on faba bean yield its components.

The highest means of biological yield (713 t / ha.), seed yield (3.43 t / ha.), number of pods/plant (3 U I), number of seeds/plant (86.28), seed weight (57.45g) and 100-seed weight (59.79g) were found with the treatment of TO, followed by Tl and T2 treatments, respectively.

On the other hand, the lowest biological yield (4.81 t / ha.), seed yield (2.26 t / ha.), number of pods / plant (22 88), number of seeds / plant (62.21), seed weight ('12.0 g) and 100-seed weight (46.H7 g) were obtailleu liulll lite LJealmCnl T2 pollinutioll \ Valmont honeybees and other insects)
