Abstract:
An experimental study was conducted in 2025 at the Faculty of Natural, Life, and Earth
Sciences in Ghardaïa, aiming to evaluate the effect of water deficit on two pea varieties
(Kelvedon and Onward) through four irrigation levels (5%, 10%, 15%, 20% ).
Statistical analyses revealed that water stress led to a significant decrease in the studied
morphological and physiological parameters, including leaf number, stem and root length, as
well as the fresh and dry weight of both aerial and underground parts, reflecting the direct
negative impact of water shortage on pea growth and productivity.
