Title: Grazing Nassella: Maintaining purple needlegrass in a sea of aggressive annuals: Journal: Rangelands; Authors: M. R. George, S. Larson-Praplan, M. Doran, and K. W. Tate; Date: 2013; Summary: This is a synthesis of 43 articles examining the effects of grazing on purple needlegrass in the California annual grasslands. Also presented here are the results of a 2-year clipping study in Northern California to examine the specific effects of frequency, timing and intensity of defoliation on purple needlegrass. ...; Agrovoc Control Words: Rotational grazing, Weeds, Rangelands; View more details about this article

Title: Effects of water table, clipping, and species interactions on Carex nebrascensis and Poa pratensis in riparian meadows: Journal: Wetlands; Authors: D. W. Martin, and J. C. Chambers; Date: 2001; Summary: Water-table depth, neighborhood species interactions and herbivory effects on the survival, tillering, biomass, and seed production of Carex nebrascensis and Poa pratensis were examined in two riparian meadows in the Humboldt-Toiyabe National Forest (Corral Canyon 39Ëš 7â€™ 13.5â€ N, 116Ëš 48â€™ 39â€ W and Kingston Canyon 39Ëš 15â€™ 30â€ N, 117Ëš 09â€™ 30â€ W). At the two sites, individual plants of C. nebrascensis and P. pratensis were grown at low ...; Agrovoc Control Words: Riparian zones, Rangelands, Ecosystems; View more details about this article

Title: Impacts of defoliation on tiller production and survival in northern wheatgrass: Journal: Journal of Range Management; Authors: J. Zhang, and J. T. Romo; Date: 1995; Summary: Tiller demographics were studied on northern wheatgrass plants that were clipped at different frequencies (every 2 or 6 weeks), starting at different dates during the growing season (May, June, July or August). Tillering varied by year depending on precipitation, soil water and previous clipping damage, but generally, plants responded to clipping by increasing tiller production. Clipping at both frequencies enhanced tiller survival, especially when clipping was delayed until later in the growing season. The results of this simulated grazing study suggest that northern wheatgrass mixed prair ...; Agrovoc Control Words: Riparian zones, Rangelands, Wildlife; View more details about this article

Title: Tiller production of grazed and clipped pinegrass: Journal: Canadian Journal of Plant Science; Authors: D. G. Stout, B. Brooke; Date: 1987; Summary: Stout and Brooke measured the effects of clipping or grazing pinegrass (Calamagrostis rubescens) at different times during the growing season, and made comparisons between simulated and actual grazing treatments. Bi-weekly clipping or grazing reduced the height, weight, and density of pinegrass tillers and pinegrass yield the following season while single defoliations after May decreased pinegrass yield but mostly by a reduction in tiller heights. Grazed plants produced more tillers, after single grazing events or between biweekly grazing events than plants that were cli ...; Agrovoc Control Words: Riparian zones, Rangelands, Wildlife; View more details about this article

Title: Grazing duration effects on wheat growth and grain yield: Journal: Agronomy Journal; Authors: S. R. Winter, and E. K. Thompson; Date: 1987; Summary: This study in the Southern Great Plains looked at grazing duration effects on winter wheat (Triticum aestivum) and grain yield. Growth and grain yield responses to grazing duration were statistically similar for all growing seasons. Compared to the grain-only treatment, wheat grazed until 1 February averaged lower leaf area index, biomass, and mean tiller weight at heading. In contrast, tiller density at heading was not reduced in the grazed wheat. Based on appearance, the grain-only treatment had superior grain yield potential every year. As the data show, grain yiel ...; Agrovoc Control Words: Riparian zones, Rangelands, Wildlife; View more details about this article
