The application of new technologies to the control and automation of irrigation processes is
becoming very important and the automatic generation and execution of irrigation schedules
is receiving growing attention. In this paper, a prototype automatic irrigation controller for
solid-set systems is presented. The device is composed by software and hardware
developments. The software was named Ador-Control, and it integrates five modules: the
first four modules simulate drop trajectories, water distribution, crop growth and yield, and the
last module ensures bidirectional communication between software and hardware. Decision
variables based on soil, crop and irrigation performance indexes were used to make realtime
irrigation decisions. A field randomized experimental design was designed to validate
the automatic controller over a corn crop during two seasons. Three treatments were
analyzed: T0) manual programmer or advanced farmer; T1) automatic scheduling controlled
by indexes based on soil simulated water content and irrigation performance; and T2)
advanced automatic scheduling controlled by simulated thresholds of crop and irrigation
indexes. Experimental results in 2009 and 2010 indicated that automatic irrigation treatments
resulted in similar maize yield but using less water than manual irrigation (10% between T0
and T1, and 18% between T0 and T2).
