  1. Optimal grazing management strategies: evaluating key concepts

    Optimal grazing management strategies: evaluating key concepts

    Item type: Journal Article • Journal: African Journal of Range & Forage Science
    Rangeland management strategies must be based on robust ecological and economic concepts if they are to be effective and profitable. Thus, the aim of this paper was to examine concepts related to grazing and resting of grassland and associated effects...
  2. Die evaluasie van droëland <em>Cenchrus ciliaris</em> L. cv Molopo vir speenkalf‐produksie in die sentrale grasveld

    Item type: Journal Article • Journal: Journal of the Grassland Society of Southern Africa
    Speenkalfproduksie op droëland Cenchrus ciliaris‐weiding is by drie veeladings onder aanhoudende beweiding ondersoek (1978–83). Verskille in beskikbare bogrondse fitomassa (BBF), speenmassa en die ekonomie van speenkalfproduksie word bespreek.
  3. ‘n Vergelyking van wei‐ en voergewasse vir die produksie van slaglammers in die Pretoria‐ Witwatersrand‐Vereeniging(PWV)‐gebied

    Item type: Journal Article • Journal: Journal of the Grassland Society of Southern Africa
    A comparison of pasture and fodder crops for the production of slaughter lambs in the Pretoria‐Witwatersrand‐Vereeniging (PWV) area. A number of pasture and fodder species were evaluated for the production of mutton with weancr lambs. Animal performance and meat production...
  4. A conceptual stocking rate model for the moderately dry mixed and sourveld

    Item type: Journal Article • Journal: Journal of the Grassland Society of Southern Africa
    Results for the 1986/87 season from 15 grazing trials situated at five sites were used to develop a qualitative model describing the relationships between stocking rate and herbage mass and between stocking rate and individual animal performance. Although it cannot...
  5. Die invloed van bemesting op die spesiesamestelling en basale bedekking van beweide veld in die Potchefstroom‐omgewing

    Item type: Journal Article • Journal: Journal of the Grassland Society of Southern Africa
    The impact of fertilization on veld in the Potchefstroom area was investigated. Nitrogen and phosphorus were applied annually from 1972/73 until 1981/82. The control plots and the fertilized plots were grazed with year‐old steers. Species composition and basal cover were...
  6. A comparison of continuous and rotational grazing on veld at two stocking rates

    Item type: Journal Article • Journal: Journal of the Grassland Society of Southern Africa
    Two rotational grazing procedures, a four‐paddock system with a 10‐day period of stay and an eight‐paddock system with a 5‐day period of stay, were compared with continuous grazing on veld. The trial was conducted 40 km south of Bulawayo in...
  7. The Potch System: An approach to the management of semi‐arid grasslands in southern Africa

    Item type: Journal Article • Journal: Journal of the Grassland Society of Southern Africa
    A host of grassland management systems have been published and recommended. Whereas earlier approaches to grassland management emphasized the systematic resting aspect, the systems published since 1966 have tended to stress the degree of utilization of the grassland sward. In...
  8. Determining milling performance of sorghum cultivars by means of abrasive decortication and roller milling techniques

    Determining milling performance of sorghum cultivars by means of abrasive decortication and roller milling techniques

    Item type: Journal Article • Journal: South African Journal of Plant and Soil
    Although roller milling has been successfully applied to produce sorghum meal, the South African sorghum milling industry mostly uses abrasive decortication milling. The first objective of this study was to develop a laboratory-scale roller milling technique for a scaled-down roller...
  9. Preliminary assessment of bambara groundnut (<em>Vigna subterranea</em> L.) landraces for temperature and water stress tolerance under field conditions in Botswana

    Preliminary assessment of bambara groundnut (<em>Vigna subterranea</em> L.) landraces for temperature and water stress tolerance under field conditions in Botswana

    Item type: Journal Article • Journal: South African Journal of Plant and Soil
    Field experiments were conducted in 2006/07 and 2007/08 in Botswana to study the response of bambara groundnut to heat stress (2006/07 season) and to heat stress and soil moisture deficit stress (2007/08 season). In both seasons selected bambara groundnut landraces...
  10. Evaluation of a class of possible simple interim management procedures for the Namibian hake fishery

    Evaluation of a class of possible simple interim management procedures for the Namibian hake fishery

    Item type: Journal Article • Journal: South African Journal of Marine Science
    During 1997, considerable scientific differences arose about the status of the Namibian hake (Merluccius capensis and M. paradoxus) resource, and as to whether the hake Total Allowable Catch (TAC) should be substantially decreased or increased. These differences revolved primarily around...
