Title: Summer grazing strategies following early-season grazing of big bluestem: Journal: Agronomy Journal; Authors: E. M. Mousel, W. H. Schacht, and L. E. Moser; Date: 2003; Summary: This study in Nebraska determined the effect of timing and frequency of grazing big bluestem (Andropogon gerardii) pasture following a May grazing period on herbage availability and herbage disappearance for the remainder of the grazing season and stand persistence. A May grazing period followed by a recovery period of 30 days or more does not affect stand persistence and improves efficiency of use of standing forage for the remainder of the growing season. Grazing at the vegetative stage in June compared with grazing at the elongation stage in June results in higher sea ...; Agrovoc Control Words: Riparian zones, Rangelands, Wildlife; View more details about this article

Title: Botanical composition, light interception, and carbohydrate reserve status of grazed 'Florakirk' bermudagrass: Journal: Agronomy Journal; Authors: C. G. S. Pedreira, L. E. Sollenberger, and P. Mislevy; Date: 2000; Summary: Pedreira et al. determined persistence of the "Florakirk" cultivar of bermudagrass (Cynodon dactylon) at different stocking rates (stubble heights of 8-,16-,24-cm) and management regimes (rest period of 7, 21, 35 days) by measuring botanical composition, light interception, rhizome mass, and carbohydrate reserves before and after grazing. Light interception increased with stubble height and was less responsive to rest period, whereas rhizome mass declined with increasing stubble height and decreasing rest periods, suggesting a tolerance mechanism of increasing p ...; Agrovoc Control Words: Riparian zones, Rangelands, Wildlife; View more details about this article

Title: Performance of 'Grasslands Puna' chicory at different management levels: Journal: Agronomy Journal; Authors: G. A. Jung, J. A. Shaffer, G. A. Varga, and J. R. Everhart; Date: 1996; Summary: Clipping trials with Puna chicory, Cichorium intybus, began in Pennsylvania in 1991 to examine the influence of management levels on herbage production and quality, suppression of floral stem production, and stand persistence. Pennlate orchardgrass, Dactylis glomerata, was used as a check species due to its high tolerance of different clipping schedules. Mean annual forage yield was greater for chicory than for orchardgrass in 1992 and 1993, with 2-year means of 9.4 and 7.9 Mg ha^-1, respectively. Total forage mass of both spec ...; Agrovoc Control Words: Riparian zones, Rangelands, Wildlife; View more details about this article

Title: Defoliation effects on production and morphological development of little bluestem: Journal: Journal of Range Management; Authors: J. J. Mullahey, S. S. Waller, and L. E. Moser; Date: 1990; Summary: Various timings and frequencies of simulated grazing were applied to little bluestem plants (Schizachyrium scoparium) over three years in order to determine the appropriate grazing management for this plant in the Sandhills of Nebraska. The effects of defoliation depended on year of treatment and precipitation, effects of defoliation generally being more apparent in dry years and in the second and third years of the study. Throughout the study grazing reduced tiller numbers, tiller weight, bud numbers, and dry matter yields of little bluestem plants, however, multiple de ...; Agrovoc Control Words: Riparian zones, Rangelands, Wildlife; View more details about this article

Title: Grazing effects on the total nonstructural carbohydrate pools in Caucasian bluestem: Journal: Agronomy Journal; Authors: S. Christiansen, and T. Svejcar; Date: 1987; Summary: The effects of light and heavy grazing on the non-structural carbohydrate concentrations of Caucasian bluestem (Bothriochloa caucasica) plant parts were determined in this study. Non-structural carbohydrate concentrations of Caucasian bluestem plants were lower in the heavily grazed pasture during the first season of grazing. However, in the second year of the study, grazing intensity did not effect carbohydrate concentrations. Carbohydrate concentrations were greatest in plant crowns in the heavily grazed pasture and in plant stems in the lightly grazed pasture. These results suggest that ...; Agrovoc Control Words: Riparian zones, Rangelands, Wildlife; View more details about this article
