Crop Water Use

By Brandy
VanDeWalle


As I have done the past couple of years, I plan to report the weekly ET in my weekly columns. The ETgage I check is in the center of the county, just south of Geneva; hopefully it will help others become aware or have an idea what the local ET is.
The ETgage I check outside of Geneva changed 2.0 inches for the week of May 25-June 1st. Corn in the V-4 stage has a coefficient of .18”. To calculate how much water, corn at V-4 stage used you simply multiply .18” x 2.0” for a weekly use of .36” or .05 inches/day. Corn approaching V-6 would have used .70”/week or .07” per day.  Fortunately, we received about 1.2” rain in this location as well.  Producers with Watermark sensors, which monitor the amount of water available in the soil profile should get them installed soon. Watermark sensors are installed early in the growing season at 1’, 2’, 3’ and in some case 4’ depths!   
For more information about ETgages and Watermark sensors, check out the NAWMN website https://nawmn.unl.edu/.  
Weed Management & Cover Crops Field Day
To see on-site demonstration of new technologies and herbicides for weed control in corn, soybean sorghum and cover crops research, plan to participate in the Weed Management & Cover Crops Field Day held June 27, 2018 from 8:30 a.m. – 3:00 p.m. Registration starts at 8:00 a.m. for this free event which will be held at  the South Central Ag Lab near Clay Center, NE.

Some topics include: comparison of herbicide programs for weed control in soybeans and corn, weed control and crop safety in MGI soybean, response of white and yellow popcorn hybrids to glyphosate Enlist DUO, or XtendiMax (26), control of Roundup Ready/Liberty Link volunteer corn in Enlist corn, weed control and crop response in INZEN sorghum, soybean yield and critical time for weed removal as influenced by soil applied herbicide. In addition, an overview of the effects of cover crops on weed suppression pests and beneficial insects will be shared.
