  1. Savanna browse production. 1: Determinants and measurement

    Savanna browse production. 1: Determinants and measurement

    Item type: Journal Article • Journal: African Journal of Range & Forage Science
    With the rapid expansion of wildlife ranching and conservation in South African savannas and the resultant increase in multi-species grazing and browsing systems, information on browse production potential is essential for determination of carrying capacity. This study, conducted on three...
  2. Estimating wood volume from canopy area in deciduous woodlands of Zimbabwe

    Estimating wood volume from canopy area in deciduous woodlands of Zimbabwe

    Item type: Journal Article • Journal: Southern Forests: a Journal of Forest Science
    In this study we tested the predictive ability of canopy area in estimating wood volume in deciduous woodlands of Zimbabwe. The study was carried out in four sites of different climatic conditions. We used regression analysis to statistically quantify the...
  3. Effects of season of burn on shrub survival, regeneration and structure in the Natal Drakensberg

    Item type: Journal Article • Journal: Journal of the Grassland Society of Southern Africa
    Four shrub species which tend to invade unburnt grassland were studied in field‐burning trials at Cathedral Peak in the Natal Drakensberg.
  4. Tegniek vir die bepaling van die hoeveelheid staande droë benutbare materiaal in sentrale hoër karooveld

    Item type: Journal Article • Journal: Journal of the Grassland Society of Southern Africa
    Die hoeveelheid benutbare materiaal (kg. ha‐1) word bereken vanaf die aantal plante per hektaar en die gemiddelde droë materiaal opbrengs per plant op ‘n 40 persent snoeibasis. Die kroonverspreidingspersentasie en kroondeursnit afmetings van die spesies word gebruik in die berekening...
  5. Preliminary observations on the ability of goats to control post‐burning regrowth in <em>acacia nigrescens/combretum apiculatum</em> Savanna in Botswana

    Item type: Journal Article • Journal: Journal of the Grassland Society of Southern Africa
    A ten hectare block which had been burned with an intense surface head fire was stocked at the rate of one goat per hectare to control the woody regrowth. After one year the block was subdivided and in one half...
  6. Quantitative description of woody plant communities: Part I. An approach

    Item type: Journal Article • Journal: Journal of the Grassland Society of Southern Africa
    Various descriptive units for woody plant communities are proposed. These are the Evapotranspiration Tree Equivalent (ETTE), Browse Tree Equivalent (BTE) and Canopied Subhabitat Index (CSI), which describe the status of a woody community in terms of potential moisture use, value...
  7. Quantitative description of woody plant communities: Part II. Computerized calculation procedures

    Item type: Journal Article • Journal: Journal of the Grassland Society of Southern Africa
    Calculation procedures for various quantitative descriptive unit‐values are described. These procedures are divided into primary and secondary calculations. The former is then divided into the calculation of spatial tree volume and preliminary calculations regarding the complete quantitative description. The latter...
  8. Canopy temperature as a plant water stress indicator for nectarines

    Canopy temperature as a plant water stress indicator for nectarines

    Item type: Journal Article • Journal: South African Journal of Plant and Soil
    Three-year-old nectarine trees of the cultivar Independence grown in free-drainage lysimeters were exposed to a wet and a dry treatment, i.e. high soil moisture content throughout or progressive soil drying respectively. The canopy temperature of the trees was measured with...
  9. Use of the SDSS test to predict the protein content and bread volume of wheat cultivars

    Use of the SDSS test to predict the protein content and bread volume of wheat cultivars

    Item type: Journal Article • Journal: South African Journal of Plant and Soil
    The relationship between the sodium dodecyl sulphate sedimentation volume (SDSS test) and the protein content and bread volume of wheat cultivars was determined to ascertain whether the SDSS test could be used to predict these parameters of baking quality. This...
  10. Measurement of radiant interception of crop canopies with the LAI-2000 plant canopy analyzer

    Measurement of radiant interception of crop canopies with the LAI-2000 plant canopy analyzer

    Item type: Journal Article • Journal: South African Journal of Plant and Soil
    The performance of the plant canopy analyzer (PCA), model LAI-2000 (LI-COR, Lincoln, NE, USA), has been tested in two separate field trials for 18 annual crop and pasture species. The objective was to recommend appropriate techniques for reliable estimates of...
