In arid and semi-arid regions, inadequate rainfall necessitates supplemental irrigation to meet crop water requirements. Selecting the appropriate method is crucial for success. A two-years field experiment was conducted in Kharameh region, Iran, to investigate the effect of different supplemental irrigation methods on fig tree yield, physiological response, and water productivity. Three irrigation methods including flood irrigation, subsurface drip irrigation, micro jet irrigation, and no supplemental irrigation (control) were applied as four treatments in five replications. Results showed that subsurface and micro jet irrigation significantly increased leaves width by 18.2%, shoot length by 27%, and shoot diameter by 13%. Micro jet irrigation also increased the amounts of chlorophyll in fig leaves by 14%, the average of total fruit numbers by 134% and the average of total fruit weight by 54% as compared to the other treatments. Also, the maximum values of water productivity were achieved in micro jet irrigation methods and decreased by 40% in subsurface drip irrigation. the potential practical applications of this research include improving fig yield, enhancing water management practices, increasing drought resilience, assessing economic viability, evaluating sustainability, and facilitating knowledge transfer and capacity building in fig production in semi-arid regions.
