Variable irrigation, nitrogen effects on corn for silage described in UW Extension bulletin

            The effects of variable irrigation and nitrogen application rates on silage corn yield, and water use efficiency under sprinkler, sub-surface drip irrigation and on-surface drip irrigation systems are discussed in a new University of Wyoming Extension bulletin.

Research at the Powell Research and Extension Center found drip irrigation systems can help save as much as 50 percent on water and also provide high yields.

The free publication Different irrigation systems and nitrogen rates improve yield and water use efficiency of corn silage, B-1326, is available in pdf, HTML and ePub formats. Go to www.edu/uwe and click on Find a Publication. Type in the title or bulletin number.

The bulletin is among many free guides, courses and videos from UW Extension to help extend skills in ranching, irrigation, small acreage management, succession, legacy and estate planning and more. YouTube video series from UW Extension include “Barnyards and Backyards,” “From the Ground Up” and “Exploring the Nature of Wyoming.”

Extension bulletins offer enterprise budgets for southeast Wyoming crops

Enterprise budgets that show estimated costs for several southeast Wyoming crops are available in separate bulletins from the University of Wyoming Extension.

Agricultural economists in the College of Agriculture and Natural Resources estimate the costs for land, labor, capital and field operations. The crop enterprise budgets and numbers are:

Conventional Alfalfa (established), B-1315-1

Conventional Irrigated Dry Edible Beans, B-1315-2

Conventional Irrigated Corn for Grain, B-1315-3

Irrigated Sugarbeet, B-1315-4

Conventional Dryland Winter Wheat/Fallow Rotation, B-1315-5

No-till Dryland Winter Wheat/Fallow Rotation, B-1315-6

Organic Dryland Winter Wheat/Fallow Rotation, B-1315-7

The free bulletins are available for viewing or downloading by going to www.uwyo.edu/uwe and clicking on the Find a Publication link. Type in the title or number. The bulletins are available in pdf, HTML or ePub formats.

UW plant pathologist describes bacterial leaf streak of corn

A new publication from the University of Wyoming Extension details bacterial leaf streak of corn.

The disease is not yet in Wyoming but is in nine states, including Nebraska, Colorado and South Dakota, said William Stump, assistant professor of plant sciences in the College of Agriculture and Natural Resources.

In “Disease alert: Bacterial leaf streak of corn,” the extension plant pathologist explains the disease symptoms and disease cycle and management.

The disease was first detected in Nebraska in 2014 and confirmed in 2016. The origin of the disease in the U.S. is not known, nor are the mechanisms by which it has extensive spread, Stump said.

The bulletin is available for free download by going to uwyo.edu/uwe and clicking on the Publications link. Type in B-1301 or the title in the search field and click on the link. The publication is available in PDF, HTML or ePub formats.
