Shadow Spaces for Water Stress Adaptation: Supplemental Irrigation Application in Rainfed Fig Production

“…In other words, fig production is dramatically affected by water stress challenges.Drought as the most important climate risk source for fig production is becoming an unavoidable limiting factor for fig growth (Marini & Piccolo, 2004). During a drought period, lack of soil moisture, severe sun radiation, high temperature variation between night and day and water evaporation from the soil surface, strongly influence rainfed fig trees (Zare et al, 2008). Such environmental stresses would result in reducing branch growth, leaf area, fruit number, leaf number,and increasing trunk sunburn, and leaf falling and consequently complete depth of fig trees (Al-Desouki et al, 2009;Zare et al, 2008).Different physiological mechanisms are used by fig trees such as drought escape, drought avoidance, drought tolerance, and survival mechanisms during droughts (Izanloo et al, 2008).…”

As a result, the utilisation of technical procedures for the irrigation management not only may influence fruit quality but may also save substantial amounts of water over a dry season (Fereres & Evans, 2006).Different physiological processes could potentially contribute to the maintenance of high yield under drought stress (Blum, 1996).…”
