Abstract
Drought stress is the main environmental factor that negatively influences Faba bean (Vicia
faba L.,) yield throughout the world. The five faba bean cultivars; Sakha 1, Sakha 2, Sakha 3, Masr 1
and Nobaria 1, were evaluated under three irrigation treatments i.e., 100% ETc (1254 m3/faddan), 80
% ETc (1009 m3/faddan) and 60 % ETc (760 m3/faddan) during the growing seasons 2015/2016 and
2016/2017. The results revealed high significant difference among varieties for all the studied agroPhysiological and biochemical under water treatments. Although all studied traits in all varieties were
significantly affected by drought but some varieties such as Sakha 1 and Nubaria 1showed drought
tolerance by maintaining the highest values of RWC, stomatal conductance, leaf temperature,
transpiration efficiency, total chlorophyll, and lowest values of osmotic potential, EL%, MDA and
proline content under drought stress, while variety Masr 1 and Sakha 3 showed drought susceptible, the
growth, yield and its components were associated with each of the agro-Physiological and biochemical
under normal and drought conditions. So, it could be concluded that the agro-Physiological and
biochemical could be used as selection criteria for improving drought tolerance and high yield under
water deficit.
