Resumen: Farmers continue to show wide differences in irrigation water use, even for a given location and crop. Irrigation advisory services have narrowed the gap between scientific knowledge and on-farm scheduling, but their success seems to have been limited. Sprinkler irrigation performance is greatly affected by meteors such as wind speed, whose short-time variability requires tactical adjustments of the irrigation schedule. Mounting energy costs often require consideration of inter- and intraday tariff evolution. Opportunities have arisen which permit to address these challenges through irrigation controllers guided by irrigation and crop simulation models. Remote control systems are often installed in collective pressurized irrigation networks. Agrometeorological information networks are available in regions worldwide. Water Users Associations use specialized databases for water management. Different configurations of irrigation controllers based on simulation models can develop, continuously update and execute irrigation schedules aiming at maximizing irrigation adequacy and water productivity. Bottlenecks requiring action in the fields of research, development and innovation are analyzed with the goal of establishing agendas leading to implementation and commercial deployment of advanced controllers for solid-set irrigation.
