  1. A Method for Monitoring Egg Production by the <em>Eucalyptus</em> Borers <em>Phoracantha</em> spp. (Cerambycidae)

    Item type: Journal Article • Journal: South African Forestry Journal
    This sampling method for monitoring P. semipunctata egg production in the forest involves attaching four strips of shed Eucalyptus bark (each 40 × 80 mm) by means of drawing pins to a freshly felled Eucalyptus log. The highest number of...
  2. Preliminary results on species selection by animals on sour grassveld

    Preliminary results on species selection by animals on sour grassveld

    A study of species selection by cattle under a system of controlled selective grazing using wheel‐point surveys and fistulated animals has demonstrated that both techniques provide valuable information on the preference shown for such species as Andropogon amplectens, Eulalia villosa,...
  3. Veld composition in relation to grazing capacity <em>die verhouding tussen veld samestelling en weidingskapasiteit</em>

    Item type: Journal Article • Journal: Journal of the Grassland Society of Southern Africa
    Present methods of evaluating veld composition in relation to grazing capacity can be criticised on grounds of subjectivity, especially with regard to the assignment of relative values to the constituent species. Data relating to botanical composition and estimated grazing capacity,...
  4. Droë massaproduksie van vyf eenjarige <em>Medicago</em>‐genotipes in die sentrale oranje‐vrystaat, soos beinvloed deur planttyd

    Item type: Journal Article • Journal: Journal of the Grassland Society of Southern Africa
    Bogrondse droë massa‐opbrengste (DM) van Medicago truncatula, cvv. Cyprus en Jemalong, M. aculeata var. inermis, cv. SA 4438, M. orbicularis, cv. SA 2552 en M. rugosa, cv. Paragosa wat op ses verskillende datums gevestig is, is in ‘n veldproef onder...
  5. ‘n Studie van ruproteïeninhoud en verteerbaarheid van vyf eenjarige <em>medica</em>go‐genotipes in die sentrale oranje‐vrystaat

    Item type: Journal Article • Journal: Journal of the Grassland Society of Southern Africa
    Die bogrondse groei van Medicago truncatula, cvv. Cyprus en Jemalong, M. aculeata var. inermis, cv. SA 4438, M. orbicularis, pv. SA 2552 en M. rugosa, cv. Paragosa, afkomstig van ‘n besproeide veldproef, is vir ruproteïen en vir in vitro‐ verteerbaarheid...
  6. A study of variations in floristic composition of highveld in the eastern Transvaal

    Item type: Journal Article • Journal: Journal of the Grassland Society of Southern Africa
    Floristic surveys of two 1500m line transects in veld provided data which indicated the nature of variations in veld composition, expressed in terms of species, palatability classes or weighted palatability classes. The transects were subjectively subdivided into units comprising relatively...
  7. A mathematical model for assessing the influence of stocking rate on the incidence of droughts and for estimating the optimal stocking rates<sup>1</sup>

    Item type: Journal Article • Journal: Journal of the Grassland Society of Southern Africa
    The Putu 11 simulation model was used to simulate veld production for each of 47 years, using weather input data and soil properties of a site at Glen. Grassland drought was defined as that condition encountered when 100 kg/ha or...
  8. Die wiskundige simulering van koolhidraattranslokasie in natuurlike grasveld<sup>1</sup>

    Item type: Journal Article • Journal: Journal of the Grassland Society of Southern Africa
    Die groeifunksies benodig vir die simulasie van produksie van ‘n Themeda triandra‐grasveld met behulp van die PUTU 11 simulasiemodel is ontwikkel. Vir die ontwikkeling van die model is die veldproduksiedata van die 1980/81 groeiseisoen gebruik waarna dit suksesvol, vir drie...
