    • Using Growing-Season Precipitation to Predict Crested Wheatgrass Yields

      Currie, P. O.; Peterson, G. (Society for Range Management, 1966-09-01)
      Forage available for use by live-stock varies with the season in which ranges are used. Specific precipitation patterns accounted for 87% or more of the variation in forage yields of crested wheatgrass grazed at different seasons in the Front Range of Colorado. Rainfall in April determined forage yields of ranges grazed in the spring; May and July rain-fall determined forage yields for fall-grazed ranges. Expected forage yields and stocking rates can therefore be predicted from precipitation measurements.

    • Seasonal and Growth Period Changes of Some Nutritive Components of Kikuyu Grass

      Kamstra, L. D.; Stanley, R. W.; Ishizaki, S. M. (Society for Range Management, 1966-09-01)
      Changes in nutritive constituents of kikuyu grass with regrowth period and season were considered. The hemicellulose fraction of kikuyu grass collected during February and April contained xylose, arabinose, glucose, and galactose regardless of length of regrowth period. Protein decreased while fibrous components and lignin (72% sulfuric method) increased as regrowth was extended. The highest in vitro cellulose digestibility occurred at six weeks regrowth. Grazing rate or clipping practices should influence the value of kikuyu in feeding programs designed to produce acceptable beef from animals slaughtered directly from grass.
    • Relating Ranch Prices and Grazing Permit Values to Ranch Productivity

      Martin, W. E. (Society for Range Management, 1966-09-01)
      The hypothesis is offered that all "outputs" produced by an investment in a cattle ranch have not been included in previous conventional analyses. These other "outputs" include tax shelters, land (and lease) appreciation, farm fundamentalism, and conspicuous consumption. Since these additional outputs are as much a part of the return on investment as is the output beef, they might well be consedered in evaluating use fees on public lands.
    • Range Reseeding Success on The Tonto National Forest, Arizona

      Judd, B. I. (Society for Range Management, 1966-09-01)
      Longevity of range plantings is important to those interested in range restoration by this means. An analysis of plantings of 1945 and 1946 through 1965 provide information on longevity for four different environments on the Tonto National Forest of central Arizona. Protective brush mulch was highly important for stand establishment under the conditions of these tests.

    • Protein, P, and K Composition of Coastal Bermudagrass and Crimson Clover

      Adams, W. E.; Stelly, M.; McCreery, R. A.; Morris, H. D.; Elkins, C. B. (Society for Range Management, 1966-09-01)
      Increasing levels of N, P and K fertilization increased total nutrient uptake and the percentage of protein, P and K, in the Coastal bermudagrass forage. P and K content of associated crimson clover increased with increasing rates of application of each nutrient. Percent recovery of N and P in the forage declined with increasing rates of fertilization of each nutrient, but percent K recovery increased with increasing K rates. N-K balance was important in maintaining an optimum K level in the forage and reducing K-deficiency symptoms. Tame pastures supplement forest range and reduce the overall cost below that of tame pastures above.
    • Opportunities In Range Management Through Association

      Higbee, F. F. (Society for Range Management, 1966-09-01)
      Small farmers and ranchers are forming grazing associations and buying land with funds advanced through the Farmers Home Administration. This article lists benefits accruing to association members and tells how economic feasibility of such projects is determined.
    • Marking Cows with Human Hair Dye

      Currie, Pat O. (Society for Range Management, 1966-09-01)
      Large, easily applied numbers could be read at considerable distance for the life of the hair coat-150 to 180 days when applied in the fall.

      Wilson, J. (Society for Range Management, 1966-09-01)
      A well-known native-grass seed producer tells how eastern Nebraska farmers and ranchers were inspired to help roll back the frontier of grass-planting knowledge in a unique and highly imaginative "do-it-yourself" grass experiment-and-education program.
    • Five Poisonous Range Weeds—When and Why They Are Dangerous

      Williams, M. C.; Cronin, E. H. (Society for Range Management, 1966-09-01)
      Three larkspurs, halogeton, and western falsehellebore were examined for seasonal variation of their contained poisons. With the exception of low larkspur, greatest concentrations of the poisons were found in the leaves. Alkaloid concentration in tall larkspurs decreased with plant maturity. Cattle losses may be reduced if tall larkspurs are avoided during early vegetative growth. The alkaloid content of tall larkspurs was increased by treatment with 2,4,5-T and silvex. Only 2,4,5-T increased alkaloid content of western falsehellebore.
    • Fees And Charges As Tools Of Public Policy—A Discussion

      Kearl, W. G. (Society for Range Management, 1966-09-01)
      This is a critique of the address by Charles J. Zwick. Clearly defining the nature of the fee problem is essential. Ranching is part of agriculture, and grazing fees should be considered as part of total agricultural policy. Basic user charge policies are examined and serious questions raised about their application.
    • Fees and Charges as Tools of Public Policy

      Zwick, C. J. (Society for Range Management, 1966-09-01)
      This paper describes the U.S. Government's policy on user charges. The basic rationale for this policy is considered, and questions are raised concerning the implementation of this policy in the grazing fee area.
    • Emergence and Survival of Intermediate Wheatgrass and Smooth Brome Seeded on A Mountain Range

      Hull, A. C. (Society for Range Management, 1966-09-01)
      Intermediate wheatgrass and smooth brome were seeded at 2 depths and 3 seasons for 3 years to determine the best season and depth for seeding mountain ranges. Emergence was best from seeding in September, October, and June, in that order. Seeding at the 0.5- and 1-inch depths gave similar results. Low emergence and high mortality of all treatments indicate the need for additional information on seeding harsh sites on mountain ranges.
    • Drylot Wintering of Range Cows—Adaptation to the Ranching Operation

      Schuster, J. L.; Albin, R. C. (Society for Range Management, 1966-09-01)
      Pregnant range beef cows adjusted to drylotting on all-concentrate grain sorghum rations and then readjusted to native range. Weight changes and reproductive performance on a limited all-concentrate ration compared favorably with commonly used methods of wintering the cow herd. Costs for two drylot methods were higher than for two pasturage methods.
    • Cooperative Range Management in Oregon—Sagebrush Control

      Gates, Dillard H. (Society for Range Management, 1966-09-01)
      Sagebrush control on suitable sites continues to be a desirable range improvement practice. In Oregon, rancher-Extension cooperative planning groups allow pooling of individual acreages resulting in extremely low bids for both herbicides and aerial application. Brush control and range seedings provide needed flexibility in range management planning.
    • Cleistogenes in Danthonia

      Dobrenz, A. K.; Beetle, A. A. (Society for Range Management, 1966-09-01)
      Cleistogamy is the behavior of flowers which do not open but which produce fruits and seeds as a result of self-fertilization. Danthonia californica, D. unispicata, and D. spicata were found to be cleistogamous, but D. intermedia produced no cleistogenes in Jackson Hole, Wyoming. Cleistogenes were capable of producing new plants and therefore may be a means for reproduction for cleistogamous species in Jackson Hole.
