Impact of soil and climate on barley (Hordeum vulgare L.) salinity tolerance in diverse arid and saline conditions.

ABSTRACT: Although barley is the fourth most cultivated cereal and is crucial for food and feed, its yields suffer in saline and arid environments due to drought and salinity, despite its tolerance. This study examines how pedoclimatic factors shape salinity tolerance in barley across different arid environments. Forty barley genotypes from the Middle East-North Africa and Pakistan were tested over two growing seasons in both semi-arid and arid locations. Crops were irrigated with saline groundwater (13 dSm^-1) or non-saline water (2 dSm^-1). Grain yield reduction served as a stress tolerance index. High temperatures exceeding 30 °C and solar radiation during various barley growth stages acted as climate indicators, while soil Potassium (K⁺)and Calcium (Ca²⁺
