Computer modeling to maximize water-use efficiency and reduce energy in irrigation. [IRRIGATE for irrigation scheduling; CORNGRO to predict effects]
A simplified irrigation scheduling model, IRRIGATE, has been developed as an educational tool for use by University personnel and in extension programs. Irrigations are scheduled using the basic premise of maximizing yields with a minimum of applied irrigation water. Use of IRRIGATE has grown rapidly in Nebraska. A mathematical model, CORNGRO, has been developed to predict daily crop water use, plant growth and crop yield for corn. CORNGRO has the capability of predicting corn yield as a result of different irrigation timing and amounts. The model can be useful in evaluating irrigation scheduling procedures in terms of yield, water conservation, energy conservation, production costs, and analyzing alternate levels of water applied.
