“…The higher NDF value of the grasses compared to alfalfa and forage kochia, particularly in Vavilov SWG when combined with its low protein demonstrates a deficiency in nutritive value. The tendency for lower NDF in the forage kochia highlights an ability to maintain forage nutritive value later than the other species, particularly when combined with CP, and supports previous observations (19,20,21).…”

“…The large differences in CP between the two grasses indicate that the grass component of any rangeland planting can play a major role in the quality of forage. Waldron et al (19) report CP of crested wheatgrass at 5% and lower during a winter grazing study, which is below the 7% CP required to maintain beef cattle, but when combined with forage kochia at 9% CP, the animal requirements were met. The Siberian wheatgrass used in this study similarly would not meet the minimum requirements of beef cattle, but either the alfalfa or forage kochia would compensate.…”

“…Requirements can be met through supplementation, but meeting requirements through species management is likely more cost effective. Waldron et al (18,19) report that forage kochia is one such species that maintains CP and will meet or exceed the minimum requirements during the late season.…”

Obtaining quality forage on semiarid rangeland is challenging. This study compared mid‐summer crude protein (CP) and neutral detergent fiber (NDF) of ‘Vavilov’ Siberian wheatgrass (Agropyron fragile), ‘Mustang’ Altai wildrye (Leymus angustus), two alfalfas (Medicago sativa), and two forage kochias (Kochia prostrata) in monocultures and binary mixtures at plant densities on 0.25, 0.50, 0.75, and 1.00‐m centers. Crude protein of alfalfa averaged 8.7%, forage kochia 9.6%, Vavilov 4.3%, and Mustang 7.9%. The CP of individual species components within mixtures was similar to their respective monoculture. The CP of forage kochia in both mixtures and monocultures increased 2.1% with increased plant spacing. The CP concentration of the total alfalfa‐grass mixtures averaged 1.2% higher than grass monocultures and 2.5% higher for the forage kochia‐grass mixtures. Forage kochia, alfalfa, and grass NDF concentration averaged 45, 50, and 63%, respectively. The NDF of individual species components was similar regardless of monoculture or mixture and plant density. However, NDF concentration of the total mixture decreased with increasing plant spacing in mixtures that included Vavilov. Under semiarid conditions, CP and NDF concentration of the material tested is influenced more by species composition and less by differences in plant density, or neighboring plants.

“…Waldron et al (22) reviewed forage kochia's livestock grazing attributes. Nutritive properties include high CP (> 7%) during the critical fall/winter grazing period (1,2,23), low non‐toxic levels of oxalates (1), acceptable digestibility (2,23,24), ability to increase rate of digestion of low quality forage (22), and high palatability to cattle (21). Waldron et al (23) recently documented that cattle grazing forage kochia during winter maintained or improved body condition without any additional protein supplementation, resulting in a 25% economic savings over alfalfa hay feeding practices.…”

Extending grazing into the winter increases the sustainability of livestock production. However, stockpiled range grasses do not meet livestock nutritional requirements. This study compared winter grazing of grass‐dominated (untreated) and forage kochia‐dominated (Kochia prostrata) (treated) rangelands. Carrying capacity, forage nutritive value, and cattle body condition were determined during late October to early January using landscape‐scale trials in Utah. Forage production on the treated rangeland (2,309 lbs/acre) was 6 times greater (P = 0.001) than the untreated rangeland, resulting in carrying capacities of 1.38 and 0.24 AUM/acre for the treated and untreated rangelands, respectively. Grass production was similar (P = 0.564) between the two rangelands, thus forage kochia was primarily responsible for the increased carrying capacity. Forage kochia had higher (P = 0.033) crude protein (11.7%) than the stockpiled grass (3.1%) and met the minimum of 7.0% recommended for gestating cattle. Although both groups of cattle improved in body condition, there was a trend (P = 0.152) for cows in the treated rangeland to improve more in body condition score (+0.7) than the cows in the untreated rangeland (+0.4). This study indicates that forage kochia can improve sustainability of livestock production by increasing rangeland carrying capacity and forage nutritive value.

“…Primary greenstrip component species (shrubs and grasses) must be site adapted, have the ability to establish among annual weeds, produce relatively low amounts of fuel, remain green over the growing season, survive burning, and tolerate grazing by wildlife and livestock (Pellant 1994;Gebhardt et al 1987;Waldron et al 2010;Harrison et al 2002).…”

Development of fine-leaved Festuca grass populations identifies genetic resources having improved forage production with potential for wildfire control in the western United States

Drought and heat tolerant fine-leaved fescue (Festuca ssp.) grasses have potential as components in rangeland greenstrips for wildfire control in semi-arid climates, although such grasses have not been evaluated under rangeland conditions. Therefore, 63 geographically diverse Festuca accessions of 11 species were evaluated for vigor, color, and biomass in 2009 and 2010 in North Logan, UT to identify grasses for use in U.S. western rangelands. Sixty-two plants representing eight species were selected in 2009 to intermate for further evaluation. Controlled biparental matings among these selections in 2010 produced 18 populations with sufficient seed to be evaluated with three commercial Festuca checks in replicated trials between 2012 and 2013 at Malta, ID, Blue Creek, UT, and North Logan, UT, where mean annual precipitation is 265, 362, and 484 mm, respectively. Plants were evaluated for color, relative vigor, biomass, seed yield, persistence, and regrowth over 2 years. Generally, four fine-leaved populations (R4S4, R4S6, R4S22, and R4S32) with parents originating from Turkey (F. valesiaca subsp. valesiaca), Russia (F. valesiaca, F. valesiaca subsp. valesiaca), Iran (F. valesiaca), and the U.S. (F. ovina) performed equal to or better than 'Durar' or 'Covar' checks. In Malta (harshest environment), the performance of these four populations compared to 'Durar' was 84-210 % for vigor, 79-90 % for color, 65-562 % for biomass, 64-296 % for seed yield, 92-117 % for persistence, and 164-454 % for regrowth, where R4S22 was superior. AFLP analysis indicated that all four populations were distinct, and that R4S4 and R4S6 grouped near 'Covar', R4S22 clustered near 'Black Sheep' and 'Durar', and R4S32 was genetically unique. These populations exhibit drought tolerance and green leaf color under harsh U.S. western desert conditions that make them amendable for use in greenstrips for wildfire control.
