• Vegetation Responses to Grazing Management on a Foothill Sheep Range

      Vogel, W. G.; Van Dyne, G. M. (Society for Range Management, 1966-03-01)
      Measurements were made of cover, yield, and vigor of plants at five locations in fenced exclosures and on adjacent range moderately grazed by sheep in fall through spring. Under the conditions of this study, four years of either deferment or moderate grazing did not cause major changes in vegetation cover, but there were improvements in the yield composition and vigor of climax-dominant perennial grasses.
    • Yield, Survival, and Carbohydrate Reserve of Hardinggrass in Relation to Herbage Removal

      McKell, C. M.; Whalley, R. D.; Brown, V. (Society for Range Management, 1966-03-01)
      Frequent removal of herbage from hardinggrass plants during the most active period of growth resulted in reduced yields and an increase in plant death. Intensive clipping also appeared to reduce the concentration of carbohydrate reserves in stem bases. Total sugar percent was higher and fructosan percent was lower in intensively clipped plants than in plants clipped only at maturity.

    • Sulphur Dioxide Fumigations of Range Grasses Native to Southeastern Arizona

      Davis, C. R.; Howell, D. R.; Morgan, G. W. (Society for Range Management, 1966-03-01)
      An experiment was conducted with 4 sulphur dioxide fumigations each year for 5 consecutive years on the same plots of 3 species of range grasses native to Southeastern Arizona. There were no statistically significant detrimental effects upon the quantity or quality of either the forage or seed produced by these grasses.
    • Root Systems of Four Desert Grassland Species on Grazed and Protected Sites

      Blydenstein, John (Society for Range Management, 1966-03-01)
      Root systems of species of Aristida, Bouteloua and Trichachne were restricted to the upper 7 inches of soil, with depth penetration of roots influenced by characteristics of the soil. Grazing affected root development by reducing the amount of branching of first-order roots and, in 2 species of Bouteloua, by decreasing total root density. Root diameter was not affected.
    • Effect of Stage of Maturity, Method of Storage, and Storage Time on Nutritive Value of Sandhills Upland Hay

      Streeter, C. L.; Burzlaff, L. R. (Society for Range Management, 1966-03-01)
      Forage yield was influenced more by differences in year and date of cutting than was nutritive value as measured by metabolizable energy and nitrogen retention. Chemical analysis showed relatively little difference in nutritive value between windrowed, bunched and baled hay, whereas standing forage had lower nutritive value than any of the harvested forages.
    • Indirect Estimation of Standing Crop

      Blankenship, J. O.; Smith, D. R. (Society for Range Management, 1966-03-01)
      Criteria such as density and cover are correlated with standing crop of alpine species. Use of these variates, however, in a double sampling design was less efficient than a single clipped sample of equal cost.
    • Livestock Management

      Boice, Robert G. (Society for Range Management, 1966-03-01)
    • Nutrient Content of Forage Ingested in Morning Compared to Evening

      Kothmann, Merwyn M. (Society for Range Management, 1966-03-01)
      Forage samples were collected from esophageal fistulated sheep in morning and evening. There was significantly more total protein and gross energy in the diet in the evening than in the morning.
    • Influence of Grass Vegetation on Water Intake of Pullman Silty Clay Loam

      Dee, R. F.; Box, T. W.; Robertson, E. (Society for Range Management, 1966-03-01)
      Water infiltration rates varied under different plant communities. The soil under blue grama absorbed 8.4 inches of water in a 2-hour period compared with 5.6 inches for windmill grass, 3.8 inches for annual weeds and 2.1 inches for buffalograss. High positive correlations existed between water intake and the amount of standing vegetation, litter, and litter and vegetation combined.
    • Composition of Two Disclimax Bluejoint Stands in Southcentral Alaska

      Mitchell, W. W.; Evans, J. (Society for Range Management, 1966-03-01)
      The composition of two disclimax bluejoint stands was determined prior to their being committed to grazing use in southcentral Alaska. The stands were essentially monotypic in their grass constituency with forbs and woody species comprising over 50% of the shoot density and well over 60% of the yield. Bluejoint was the only plant of grazing value found in quantity in the two communities.
    • Cumulative Effects of Clipping on Yield of Bluebunch Wheatgrass

      Wilson, A. M.; Harris, G. A.; Gates, D. H. (Society for Range Management, 1966-03-01)
      Bluebunch wheatgrass is particularly susceptible to defoliation injury during the boot stage. At this stage, grazing at ground-level for three or more consecutive years many result in almost complete disappearance of bluebunch wheatgrass from rangeland.
    • Effects of Harvester Ants on Production of a Saltbush Community

      Wight, J. R.; Nichols, J. T. (Society for Range Management, 1966-03-01)
      The presence of denuded areas caused by harvester ants did not lower the production of a Nuttall saltbush community in the Big Horn Basin of Wyoming. Increased saltbush production around the perimeter of the denuded areas compensated for the absence of saltbush within the denuded area.
    • Alkali Sacaton: Its Merits for Forage and Cover

      Hickey, W. C.; Springfield, H. W. (Society for Range Management, 1966-03-01)
      Alkali sacaton provides fairly abundant forage, is an effective ground cover, withstands relatively heavy grazing, and may offer possibilities for reseeding. It probably is a more valuable grass than generally realized and merits more attention and research.
    • Brachiaria dura, a Promising New Forage Grass

      Verboom, W. C. (Society for Range Management, 1966-03-01)
      In Barotseland, Zambia, in Central Eastern Africa a grazing and ecological survey has revealed Brachiaria dura to have unusually favorable characteristics as a forage grass on sandy soils of low fertility. Chief among these characteristics are relatively high protein content, a long period of succulence, and a special root adaption to sandy soil.
