Crop Water Use for Sept. 9-16, 2025

By Gary Stone - Extension Educator, Xin Qiao - Irrigation and Water Management Specialist

Graphic for weekly crop water use updates in the Nebraska Panhandle, featuring a close-up of a corn leaf with dew and links to statewide GDD and ET data at cropwatch.unl.edu/gdd-et and agritools.unl.edu.

As crops reach maturity, weekly use falls fast — use this week's data to target inches where they still pay.

The estimated crop water use for Nebraska Panhandle and northeast Colorado crops for the previous week is shown in the tables below. The tables are based on data gathered and calculations made by Gary Stone, Nebraska Extension educator, and Dr. Xin Qiao, extension irrigation and water management specialist, both based at the UNL Panhandle Research and Extension Center in Scottsbluff, Nebraska.

Crop water use will vary across the Panhandle due to variations in ET, crop growth stage, temperature, soil type, wind and precipitation events. Crop water use will assist growers with irrigation scheduling and efficient water application and use.
