The horticultural management of rainfed fig orchards under water stress conditions has developed using supplemental irrigation (SI) strategy. Diffusion of SI technology requires dealing with orchardists' demands. The aim of this descriptive survey research was to investigate factors contributing to the SI application by fig growers under semi-arid conditions. Orchard-system, demographic features, attitudinal patterns, and economic characteristics of fig growers were assessed to identify the characteristics that lead to, or detract from SI application adoption, when rainfall is insufficient for normal plant growth. The sampling frame contained 377 out of 7,530 fig orchard addresses in Estahban region, southern Iran. Results revealed that higher yield, fruit quality including fruit size (as an indicator for fruit weight), and color of fig fruit were the most important components influencing fig growers' perception of SI usefulness. SI technology adopters and non-adopters indicated statistically different results in terms of average income and number of trees. The current research can benefit policymakers, researchers, farmers, water associations, etc. in determining the appropriate supplemental irrigation amount and time, and will be of significant value in water supply planning and higher agricultural productivity, considering the limited water resources.
