Alfalfa seed has already been planted to start a three-year study in three states to develop potassium information and improve alfalfa production and quality within the central and western U.S.
Plots were seeded earlier this month at the James C. Hageman Sustainable Agriculture Research and Extension Center near Lingle, with additional studies near Fort Collins, Colo., and Manhattan, Kan., said Anowar Islam, University of Wyoming Extension forage specialist.
The field studies are part of a $250,000 USDA grant Islam received. Collaborators include forage specialist Joe Brummer of Colorado State University and forage management assistant professor Doo-Hong Min at Kansas State University.
Islam said the benefits could be extensive.
“Our potassium fertility management program will improve persistence of alfalfa stands through better nutrient management,” he said.
Scientists will focus on alfalfa growth, yield and quality by applying different levels of potassium under two cutting intervals. Potassium uptake data and forage quality of selected alfalfa cultivars (low lignin vs. conventional) at different stages will be collected.
Information will be disseminated through a planned regional alfalfa workshop with state-specific results through local extension programs and by articles and bulletins.
Islam said the information will modify outdated central and western U.S. alfalfa soil fertility guides. The group will initiate an alfalfa community of practice within eXtension, a long-term venue of communicating the latest findings on alfalfa nationally and internationally.

Forage production and management and tools to help alfalfa and forage growers produce the best possible yield and quality are part of the Wyoming Forage Field Day Tuesday, June 14, at Sheridan.
The fifth-annual event is 8 a.m.-4 p.m. at the Sheridan Research and Extension Center (ShREC) at Sheridan College. Registration, encouraged by June 3 to ensure a free lunch, is free, and the event is open to the public.
University of Wyoming Extension forage specialist Anowar Islam said the event is farmer-focused, “especially for those who want alfalfa and improved forages in their cropping/animal production systems and improve yield, quality and profitability.”
Full program details are at bit.ly/forageday.
There are more than 13 presentations, ranging from 10 to 40 minutes. A panel of producers is in the afternoon and machinery and equipment demonstrations end the day.
Register by calling ShREC at 307-673-2856 or at email@example.com, or contact Islam at 307-766-4151 or firstname.lastname@example.org.
Two new publications from University of Wyoming Extension give growers a closer look at pests and beneficial insects affecting alfalfa crops.
Damage from insects includes seedling death, stunted growth, skeletonization and other leaf deformity. “Insects in Wyoming Alfalfa” is available online at bit.ly/insectsinalfalfa. “Aphids in Alfalfa” is available at bit.ly/aphidsinalfalfa.
“Insects in Wyoming Alfalfa” is an easy-to-use guide to eight leaf chewers, sap suckers
and the blister beetle, whose toxin is poisonous when consumed by horses. It also includes beneficial insects and spiders that aid alfalfa crops by serving as pest predators and parasites and plant pollinators. The guide contains descriptions, photos and actual-sized silhouettes.
“Aphids in Alfalfa” gives a more in-depth look at this common and sometimes serious pest, noted for piercing, sucking mouthparts, rapid reproduction and ability to reduce yields by several means. Two tables in this bulletin guide producers in counting aphids and beneficial lady beetles to determine if insecticide treatment may be necessary.

The 2015 FDB also highlights vegetable and herb production, irrigation practices, fertilization, weed control and plant and livestock disease research.
“This bulletin contributes to our efforts to inform Wyoming citizens and others of the research being conducted at the four WAES research and extension centers, by members of the University of Wyoming College of Agriculture and Natural Resources and by others who have received funding from WAES,” said WAES director Bret Hess.
Approximately 90 one- and two-page articles summarize completed and in-progress research projects within the College of Agriculture and Natural Resources, at the R&E centers near Laramie, Lingle, Powell and Sheridan, and at participating farms and ranches in Wyoming.
