Stocking rate is a fundamental management factor that has major impacts on animal performance, profitability, and long-term sustainability of native range ecosystems. This research was conducted to determine the effects of stocking rate on performanc

Traditional management of sand sagebrush (Artemisia filifolia) rangelands has emphasized sagebrush control to increase forage for livestock. Since the 1950s shrub removal has been primarily achieved with herbicides. Concerns over declining lesser pra

To evaluate the effects of sand sagebrush (Artemisia filifolia Torr.) control in native rangelands on cattle performance, 15 pastures (10 to 21 ha each) were selected in northwest Oklahoma. Eleven pastures had been sprayed with 2,4-dichlorophenoxyace

Before planting millions of hectares to switchgrass (Panicum virgatum L.) monocultures for producing biomass feedstock for biorefineries, it has been proposed that monocultures be tested against polycultures so, among other issues, the economics of b

Comparisons of stocking rates across sites can be facilitated by calculating grazing pressure. We used peak standing crop and stocking rates from six studies in the North American Great Plains (Cheyenne, Wyoming; Cottonwood, South Dakota; Hays, Kansa

When two forage species are grown together they can be compatible, compete, or allelopathic with each other. We estimated the combining ability effects for introduced, cool- (CS) and warm-season (WS) grasses and legumes grown in binary mixtures. Six

The density at which a crop is grown is known to affect its growth and quality, but little is known about how plant density affects the growth of native perennial forage grasses. The objectives were to investigate the effects of plant population dens

Many forage-livestock systems in the Southern Plains depend on the use of winter wheat (Triticum aestivum L.) and rye (Secale cereale L.) to support rapid gains of growing beef cattle (Bos taurus L.) from November through May. Complementing these ann

Post-fire forage growth is known to be a strong attractant for large herbivores. However, fire has generally been avoided as a grazing distribution tool for fear of localized over utilization of forage resources. Our objectives were to examine whethe

Knowledge of the relationship between stocking rate or grazing intensity and plant production is fundamental to the sustainable management of rangelands. The general management paradigm is that plant production declines as stocking rate increases. Ou
