Egypt's arid climate and limited water resources present significant challenges hindering the achievement of sustainable agriculture. To address these challenges, innovative strategies are required to optimize water use and enhance crop productivity. Effective management of these constraints is essential for developing agricultural practices that can sustain food production and meet the demands of a growing population. This review examines the effects of soil amendments such as biochar, zeolite, and compost, as well as foliar nutrition involving boron, copper, and selenium, on plant growth and yield quality under deficit irrigation conditions. Deficit irrigation is a water conservation strategy that aims to minimize crop yield reduction while conserving water, thus necessitating improved soil and plant management techniques. Recent research highlights how these soil amendments and nutritional interventions can significantly improve water retention, increase nutrient availability, and enhance plant stress resilience. By focusing on amendments like biochar, zeolite and compost, alongside foliar treatments of essential micronutrients, this article underscores their potential to enhance water use efficiency and boost crop resistance to environmental stresses. These strategies are vital for advancing sustainable agricultural practices, particularly in regions grappling with water scarcity and climatic challenges. The current study emphasizes the importance of these approaches in supporting resilient and productive farming systems, ultimately contributing to more sustainable agricultural practices in water-limited environments.
