“…Total forage DM yield of triticale selections in the current study are similar to reported yields of 4.7 to 7.9 Mg/ha in drier environments in the CHP region (9). Dry matter yield of Willow creek (forage winter wheat released by Montana State University) in this study was lower than those reported for Montana and eastern Wyoming (3). Seasonal total DM yield of Willow creek ranged from 2.9 to 5.1 Mg/ha, lower than DM yield of other small grains evaluated in this study.…”

Forage production and nutritive value of three selections each of winter rye (Secale cereale L.), and triticale (X Triticosecale Wittmack), and four selections of wheat (Triticum aestivum L.) were evaluated over three growing seasons (2008‐2011) in Wyoming. Average fall forage productivity was < 1.0 Mg/ha and lower (P < 0.0001) than forage production in spring and summer. Average spring dry matter (DM) yield was 3.2 Mg/ha and greater than summer yield (2.0 to 2.6 Mg/ha) except in 2010‐2011. Total seasonal forage production was not different (P > 0.05) among rye and triticale selections except in 2009‐2010. Total seasonal forage DM production among triticale and wheat selections was not different in two out of the three growing seasons. Forage crude protein (CP) of rye selections (127 to 196 g/kg) was consistently lower than triticale (151 to 208 g/kg) and wheat (162 to 235 g/kg). Average in‐vitro dry matter digestibility (IVDMD) of all small grains was above 650 g/kg (679 to 863 g/kg). Acid detergent fiber (ADF) and neutral detergent fiber (NDF) were different among small grain species (rye > triticale > wheat). Theseresults indicate that small grains can provide acceptable forage yield with superior quality for feeding livestock during winter and early spring in the central High Plains (CHP).

“…Therefore, protein supplementation may be required to improve animal intake and performance (6). Small grain forages have potential for beef cattle production in the CHP and other western mountain states (3,13). There is limited information on seasonal forage productivity and nutritive value of small grains in the CHP region of Wyoming.…”

Although the United States has pursued rapid development of corn ethanol as a matter of national biofuel policy, relatively little is known about this policy's widespread impacts on agricultural land conversion surrounding ethanol refineries. This knowledge gap impedes policy makers' ability to identify and mitigate potentially negative environmental impacts of ethanol production. We assessed changes to the landscape during initial implementation of the Renewable Fuel Standard v2 (RFS2) from 2008 to 2012 and found nearly 4.2 million acres of arable non-cropland converted to crops within 100 miles of refinery locations, including 3.6 million acres of converted grassland. Aggregated across all ethanol refineries, the rate of grassland conversion to cropland increased linearly with proximity to a refinery location. Despite this widespread conversion of the landscape, recent cropland expansion could have made only modest contributions to mandated increases in conventional biofuel capacity required by RFS2. Collectively, these findings demonstrate a shortcoming in the existing 'aggregate compliance' method for enforcing land protections in the RFS2 and suggest an alternative monitoring mechanism would be needed to appropriately capture the scale of observed land use changes.

“…Subplots were three fall‐planted winter cereals and a single spring‐planted cereal. Fall‐seeded cereal entries were ‘Bobcat’ triticale (Salmon et al, 2000), and ‘Yellowstone’ (Bruckner et al ., 2007) and ‘Willow Creek’ (Cash et al ., 2009) winter wheat. Spring‐seeded ‘Hays’ barley was included as a spring‐planted control.…”

Fall‐seeded cereals harvested as forage may be suitable rotation crops in the spring grain region of the northern Great Plains (NGP). A 3‐year field study was conducted to determine the biomass, forage quality, weed community, and water use dynamics of cereals grown for forage with or without post‐emergence broadleaf weed control. Fall‐seeded cereals were ‘Willow Creek’ awnletted winter wheat (Triticum aestivum L.), ‘Yellowstone’ awned winter wheat, and ‘Bobcat’ awnletted triticale (× Triticosecale Wittm.). ‘Hays’ hooded barley (Hordeum vulgare L.) was included as a spring‐planted control. Willow Creek had greater biomass yield than other fall‐seeded cereals, ranging from 4265 to 8435 lb/acre dry matter. Hays barley and Willow Creek had similar forage yield for 2 years, but Hays was the lowest yielding entry in 1 year. Water use (WU) and water use efficiency (WUE) were higher for Willow Creek than Yellowstone or Bobcat, while WU and WUE of Hays were intermediate to fall cereal entries. All entries had acceptable levels of crude protein and fiber for beef cattle maintenance diets. Willow Creek had the lowest crude protein concentration all three years despite harvesting entries at similar maturity. Weed biomass varied with cereal entry × year, but never exceeded 8% of total biomass for fall‐seeded cereals. In the absence of postemergence weed control, weed seed production was low with all entries. Fall‐seeded cereal forages are well adapted to the spring‐seeded cereal region of the semiarid NGP.
