This book explores the impact of different irrigation strategies on the agro-physiological parameters of a young Ménara olive plantation. The study aims to optimize irrigation techniques to maximize olive tree growth and health by analyzing various agro-physiological indicators such as water content, photosynthesis and biomass. The results show that certain targeted irrigation strategies can significantly improve the performance of young olive trees, contributing to better water management and increased agricultural productivity. These findings offer promising prospects for optimizing agricultural practices in olive-growing regions.
