Accomplishments
Colorado
A project was completed that looked at the feasibility of using brassicas for fall forage to extend the grazing season. A 4-way mixture of a turnip, rape, radish, and hybrid has proven successful. Because of the high quality of the brassicas, it is advantageous to mix them with oats to increase the fiber in the diet. When this was done, weaned heifers were able to gain about 2.5 pounds per day without the need for any addition supplementation. The brassica mix was also shown to establish well and to be an economically viable management practice when interseeded into standing corn at the V6 growth stage to provide a protein supplement when grazing the corn stalks in the fall. By extending the grazing season into the fall using brassicas, producers can significantly reduce their need for feeding of preserved forages thereby reducing input costs.
Another project was completed that investigated the feasibility of fallowing or partially irrigating grass and alfalfa hayfields on the western slope of Colorado to free up water for municipal/industrial uses or to meet downstream compact obligations. High elevation grass hayfields took one full season to recover following one year of complete fallowing. If producers are to participate in this type of water banking approach, they will need to be compensated for 2 seasons of lost production, not just for the year of fallowing. Alfalfa recovered from partial irrigated for 2 consecutive seasons and was more vigorous compared to the fully irrigated control. Due to its extensive root system and inherent drought tolerance, alfalfa is a better choice for freeing up water for other uses. However, there is not as much alfalfa acreage compared to grass on the western slope of Colorado, so participation by grass hay producers will be required if enough water is to be made available to meet water bank needs.

Utah
Recent Research Summary and Impacts
Earl Creech and his graduate student Jason Clark’s research showed that glyphosate-resistant alfalfa can be effectively terminated with herbicides and tillage, alone or in combination. Jason’s research further showed that silage corn can be grown after alfalfa in Utah with or without tillage and that nitrogen fertilizer does not appear to be necessary for first year corn after alfalfa, which would greatly reduce the fertilizer N costs for growers who rotate corn with alfalfa in Utah and across the West.
Studies by Jennifer MacAdam and collaborators demonstrated that enteric methane emissions from beef cows grazing cicer milkvetch (Astragalus cicer L.) and birdsfoot trefoil (Lotus corniculatus L.) pastures was significantly reduced relative to cows grazing meadow bromegrass (Bromus biebersteinii Roem. & Schult.) pasture.
In consumer sensory panels, ribeye steaks from steers finished on meadow bromegrass was less tender and juicy than steaks from steers finished in the feedlot or on birdsfoot trefoil. However, the concentration of omega-3 fatty acids was greater in the intramuscular fat of steaks from both birdsfoot trefoil- and grass-finished beef relative to steaks from feedlot-finished beef.

Research Activities (Fransen)
- Winter canola. This is a new area of cooperative investigations. We have three funded projects focused on canola for forage and grain production.
- We are into the second year of a N:S fertility trial where canola is planted in mid-August and harvested for silage in mid-October. Because of the low DM of canola forage, half of the fertility treatments are mixed with alfalfa cubes and half are controls. This research is supporting a M.S. Animal Science student. We collected soil and whole plant samples at key growth stages and harvested for grain in early July.
- This study is planted at WSU-Prosser and off-station at Ted Durfey farms and starts by growing inoculated spring peas with harvest in late June compared with spring fallow. July organic amendments of compost, manure, compost + manure are compared with August inorganic fertilizer for a mid-August planting. Half of all plots were harvested for simulated grazing in mid-October. Soil water samples for nitrates were collected via lysimeters in the fall and will continue in the spring until grain harvest. We have experienced great difficulty getting adequate soil water samples. To collect any soil water at all, we must greatly over-irrigate to cause any leaching (much more than any practical crop ET would recommend). This causes us to question how applicable soil water collection samples and methods are to real world applications. Crops will be harvested for grain in the summer of 2016. The trial will be repeated in 2017 on adjacent land. This study is funded by Western Region SARE.
- Our final study is funded by WOCS to diagnose why winter canola will survive in some regions / management protocols and not in many others. This study is planted at Othello (north Basin) and Prosser.
- Switchgrass. We continue intercropping switchgrass into hybrid poplars at the GreenWood Resources farm at Boardman, OR. This is our final year and we have requested a one-year no cost extension. All that remains is to revise manuscripts and conduct the life cycle analysis that will be done in 2016 when the remaining lab work is completed. We have completed the switchgrass intercropped with alfalfa study and that manuscript has been submitted.
- Grant proposals. (1) We have submitted a DOE grant for switchgrass conversion from feedstocks grown at Prosser and Paterson. This project has been in development since 2010 and the soils/crops are now in the state where effective treatments can be applied. From collaborative studies with the University of Washington, we have learned there is a new world of microorganisms in our soils, AOA, that I think have a profound effect on switchgrass productivity. In the future, with perennial cellulosic grasses, I think we’ll find even greater positive responses from these compared to bacteria. (2) Cooperator on NIFA Water Challenge grant and (3) Food Security grant.

Wyoming
Accomplishments
Winterhardy peas were developed to reduce the dryland fallow in the regions. Dryland winter wheat is the most commonly grown crop in eastern Wyoming. Due to limited and highly variable precipitation (~15 inches per year, 66% between April and August), fallow remains a common practice to conserve soil moisture and stabilize succeeding crop yields by providing successful establishment in most dryland areas in Wyoming. However, a fallow combined with tillage limits productivity and sustainability of a farm through increasing soil erosion, depleting soil organic matter, and reducing C-fixation and N assimilation. The objectives of this study were to develop winterhardy pea cultivars for both human and livestock (grain and/or forage) consumption through hybridization among diverse lines/cultivars and selection from advanced pea generations; and to test new winterhardy cultivars of pea in the dryland cropping system. The desirable lines were tested at two locations for two years with an eventual release of superior line(s) as new cultivar(s) well adapted to Central Great Plains.
Forages are very important in Wyoming and the mainstay of livestock production. Alfalfa is an important forage crop in the US and produces quality forage and persistent when grown as sole stands. However, the bloating characteristic and poor tolerance for acidic soils make other legumes such as birdsfoot trefoil and sainfoin viable alternatives. The major objective of this study is to assess the effects of different ratios of grass-legume mixtures on forage yield, quality and persistence. Additional objectives are to determine cost effectiveness of establishing sole grass (fertilized with N), sole legumes, and grass-legume mixtures and how efficient these practices are utilizing irrigation water. Data being collected include plant height, percentage of weed, water use efficiency, nutrient use efficiency, cost and revenue ratio, and forage yield and quality. It is anticipated that the results will help recommend the best grass-legume mixture ratios that will be profitable to Wyoming producers.
Demand for new and suitable plant materials is a long-term issue and is increasing continuously especially in the Intermountain West regions. The objective of this study is to evaluate different advanced lines of C3 grasses with the inclusion of some local checks in relation to their growth, yield, and quality response to irrigation, drought, and planting time. Species used in this study include tall fescue (seven lines), tall wheatgrass (three lines), western wheatgrass (five lines), and wildrye (two lines). Fall planting was made in late August 2008 whereas spring planting was in early May 2009. Data collected on different growth parameters, persistence, and forage quality from 2009 - 2014 for both plantings seems to be different among species and lines. Long-term data collection will help select and develop superior and well-adapted cultivars.
Impact
Research programs from University of Wyoming have made selection for well-adapted high performing accessions/lines which resulted in development of cultivars that are suitable for Wyoming and neighboring states. This contributed to the improvement of productivity of local and regional producers and in the long-run, will provide economic benefits.
Studies on determining cost effectiveness of establishing sole grass (fertilized with N), sole legumes, and grass-legume mixtures and how efficient these practices are utilizing irrigation water have positive impacts. Results will help recommend the best grass-legume mixture ratios that will be profitable to Wyoming producers by significantly reducing production costs.

Impacts
- The research and extension/training programs for the western US region are continuing to have positive impacts not only locally but regionally and internationally through visiting scholars and international exchange programs and projects. Selection of well-adapted high performing accessions/lines/cultivars will result in development of cultivars that will be specifically suitable for local state and neighboring states. This will contribute to the improvement of productivity of local and regional producers and provide economic benefits. The locally and regionally developed new technologies and management strategies including grazing management will enhance producers’ ability to adopt these in their production systems.
