Abstract
Drought is a universal problem that affects plant production and degrades soil. The point of this study was to appraise the physiological responses of Paspalum vaginatum to water stress and to attempt to minimize its impacts using organic amendment in arid and semi-arid climates. In winter 2019, a pot investigation was undertaken for this reason in the south of Morocco on a plastic pot filled with sandy loam soil and various levels of peanut hull biochar and compost on 20% of water holding capacity. The results revealed that adding biochar and compost enhanced photosynthesis, stomatal traits, and water availability in plants cultivated in amended treatments compared to untreated treatments. This study could be a prominent reason for managing luxury golf courses in arid zones.
