Most Arizona growers irrigate their Durum wheat by flooding the fields, but a new study shows the crop grows more efficiently under overhead sprinklers.
According to the study, using overhead sprinklers saves on water use and gives crops a much better chance at using all the nitrogen fertilizer applied.
“More efficient watering systems are really needed here in the West,” said lead researcher Kevin Bronson. “We have very high production but historically and in the last 30- to 40-year time period there hasn’t been as much attention paid to the efficiency of our irrigation systems.”
Bronson added that, because of the continuing drought, more growers will be looking for more water-efficient irrigation.
