  1. Die evaluering van vier <em>Eragrostis curvula</em> ekotipes met weidende skape

    Item type: Journal Article • Journal: Journal of the Grassland Society of Southern Africa
    The evaluation of four Eragrostis curvula ecotypes with grazing sheep. Four ecotypes of Eragrostis curvula, namely, Cape Province 5, Ermelo, Pearston 204 and Makwassie 150 were evaluated in a grazing trial with sheep, at three stocking rates, during two growing...
  2. Exploring basic biochemical constituents in the body tissues of South African abalone <em>Haliotis midae</em> reared in shore-based mariculture systems

    Exploring basic biochemical constituents in the body tissues of South African abalone <em>Haliotis midae</em> reared in shore-based mariculture systems

    Item type: Journal Article • Journal: African Journal of Marine Science
    The study quantifies the effects of season, age and feeding regime on glucose, glycogen, proteins and lipids in abalone Haliotis midae tissues, and to assess water loss during simulated live export. Abalone of two age classes, younger (∼30 months old)...
  3. Ontogeny of <em>Themeda triandra</em> tillers in the false thornveld of the eastern cape

    Item type: Journal Article • Journal: Journal of the Grassland Society of Southern Africa
    Marked populations of Themeda triandra tillers were sequentially sampled at fortnightly intervals under normal conditions and without moisture stress respectively, covering a period from tiller initiation through to senescence after flowering. Parameters recorded were height of shoot apex, tiller mass,...
  4. The influence of different forms and concentrations of nitrogen on the growth and metabolism of <em>digitaria eriantha</em> and <em>chloris Gayana</em> grown under saline conditions

    Item type: Journal Article • Journal: Journal of the Grassland Society of Southern Africa
    Chloris gayana and Digitaria eriantha plants were watered with nutrient media containing a high concentration of sodium chloride (150 mM) and either high (200 mg/l) or low (25 mg/l) concentrations of nitrate nitrogen and ammonium nitrogen. Dry mass and leaf...
  5. Estimating grass fuel loads with a disc pasture meter in the Kruger National Park

    Item type: Journal Article • Journal: Journal of the Grassland Society of Southern Africa
    The major portion of the fuel load in the savanna areas comprises surface fuels in the form of the standing grass sward. The disc pasture meter was successfully calibrated for estimating grass fuel loads in the main landscapes of the...
  6. Interrelationships between veld condition, herbage mass, stocking rate and animal performance in the Tall Grassland of Natal

    Item type: Journal Article • Journal: Journal of the Grassland Society of Southern Africa
    Grazing trials were established at three sites in the Tall Grassveld of Natal. The objectives were to determine (a) patterns in herbage mass in relation to veld condition, stocking rate and commencement of spring grazing, and (b) animal performance in...
  7. 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...
  8. A comparison of four different standards of reference for the animal unit for Determining stocking rate

    Item type: Journal Article • Journal: Journal of the Grassland Society of Southern Africa
    No single standard of reference for the animal unit (AU) for determining stocking rates has materialized. Often, therefore, it is not clear which standard of reference for the AU or which method of determining stocking rate has been used in...
  9. Relations between soil factors and herbage yields of natural grassland on sandy soils in the south‐eastern Transvaal

    Item type: Journal Article • Journal: Journal of the Grassland Society of Southern Africa
    Forty systematically‐placed observation points were established in a 1.5‐ha area of floristically unifoim veld in which productivity varied spatially. At each point grass yields were determined by harvesting quadrats at eight‐week intervals during the growing season, and the volumetric water...
  10. Influence of period of deferment before stocking spring‐burnt sourveld on sheep performance and veld productivity

    Item type: Journal Article • Journal: Journal of the Grassland Society of Southern Africa
    Spring‐burnt sourveld was stocked with Merino lambs after three different periods of deferment from the time of start of growth in spring. During three seasons, average seasonal livemass gains on veld which was stocked shortly after the start of growth...
