ResumenDespite current technological developments and intense capacity building, farmers continue to show wide differences in irrigation water use, even for a given location and crop. Sprinkler irrigation performance is affected by a number of meteors, particularly wind speed. The short-time variability of wind speed requires tactical adjustments of the irrigation schedule. Additionally, energy costs often require consideration of the time evolution of the tariff along the day and among contiguous days. Opportunities have arisen in the last decades which permit to address these challenges through irrigation controllers guided by irrigation and crop simulation models. Among these opportunities: remote control systems installed in collective pressurized irrigation networks; networks of agrometeorological weather stations; and specialized databases for the management of Water Users Associations. In this paper, an irrigation controller configuration based on the use of solid-set sprinkler irrigation and crop simulation models is presented. This controller can develop, update and execute irrigation schedules aiming at maximizing irrigation adequacy and water productivity. Research, development and innovation bottlenecks are assessed to establish agendas leading to the commercial deployment of advanced controllers for solid-set sprinkler irrigation.
