  1. Overseeding of <em>Eragrostis curvula</em> on north‐eastern Sandy Highveld

    Overseeding of <em>Eragrostis curvula</em> on north‐eastern Sandy Highveld

    A small plot trial to investigate the possibilities of directing changes in the botanical composition of fertilized veld by oversowing demonstrated the potential of this technique for the establishment of improved pastures in non‐arable situations. The improved return on fertilization,...
  2. Influence on a North‐Eastern Sandy Highveld sward of winter utilization by sheep

    Influence on a North‐Eastern Sandy Highveld sward of winter utilization by sheep

    North‐Eastern Sandy Highveld was utilized selectively by sheep grazing alone in winter with a supplementary lick. Winter utilization in four consecutive years had no detrimental effect on production, cover or seed production but care should be exercised in recommending this...
  3. The utilization of <em>eragrostis curvula</em> and <em>pennisetum clandestinum</em> pastures for growing out and finishing young beef steers

    The utilization of <em>eragrostis curvula</em> and <em>pennisetum clandestinum</em> pastures for growing out and finishing young beef steers

    Results obtained from three observation trials to assess the feasibility of utilizing Eragrostis and kikuyu with young beef steers are presented. Although both grasses were characterized by a high grazing capacity the performance of livestock, on an individual basis, was...
  4. The implications, with respect to production and nutritional value, of different stages of harvesting <em>eragrostis curvula</em> hay

    The implications, with respect to production and nutritional value, of different stages of harvesting <em>eragrostis curvula</em> hay

    A small plot cutting trial conducted over a five year period has demonstrated that dry matter production and crude protein content are negatively related when different frequencies of defoliation are applied. Frequent harvesting at a leafy stage produced the most...
  5. The influence of feedback on hay pastures

    The influence of feedback on hay pastures

    The feeding of hay to sheep or cattle on an Eragrostis curvula pasture during the winter months has a most beneficial effect on the response of the pasture to fertilization in subsequent seasons. Low rates of feedback (10 t/ha) had...
  6. Use of the dry‐weight‐rank method of botanical analysis in the eastern Transvaal Highveld

    Use of the dry‐weight‐rank method of botanical analysis in the eastern Transvaal Highveld

    The dry‐weight‐rank method of botanical analysis was tested in the highveld of the Eastern Transvaal and was found to be an efficient and accurate means of determining the botanical composition of veld herbage. Accuracy was increased by weighting ranks on...
  7. 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,...
  8. 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...
  9. The influence of nitrogen fertilization, spring burning and height of stubble on hay and seed production of <em>eragrostis curvula</em> <sup>1</sup>

    Item type: Journal Article • Journal: Journal of the Grassland Society of Southern Africa
    This investigation, conducted over a three‐year period, emphasized the strong effect of nitrogen fertilization on both hay and seed production. The optimum level of nitrogen, for conditions on the Eastern Highveld being 100–150 kg N/ha applied in spring, followed by...
  10. The influence of level and distribution of nitrogenous fertilizer on the dry matter production of <em>Eragrostis curvula</em>

    Item type: Journal Article • Journal: Journal of the Grassland Society of Southern Africa
    212 kg N/ha was the most profitable level. With the probability of poor seasons (when 106–159 kg N/ha was more profitable), the optimum level of spring fertilization being in the region of 100 kg N and the improved distribution of...
