  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. Grazing of <em>raphanus sativus</em>. L (Japanese Radish)<sup>1</sup>

    Item type: Journal Article • Journal: Journal of the Grassland Society of Southern Africa
    The performance of young woolled sheep was markedly better when grazing Japanese radish early in winter, when more leaf was available .Continuous grazing resulted in better performance than rotational or zero grazing.
  3. Evaluation of veld potential in east griqualand using beef cattle under two grazing management systems

    Item type: Journal Article • Journal: Journal of the Grassland Society of Southern Africa
    Beef production from veld, in the short term, was found to be greater under a continuous grazing system than under a rotational grazing system. Average daily gains decreased from a maximum in late‐spring and the highest three‐year mean value was...
  4. Influence of grazing management on the production of an irrigated grass/legume pasture in the Rûens area of the Southern cape

    Item type: Journal Article • Journal: Journal of the Grassland Society of Southern Africa
    The production of an irrigated grass/legume pasture was determined using Merino ewes on rotational and continuous grazing systems. The clover content of the pasture declined, while the grass content increased under both systems. The lucerne content of the rotationally‐grazed pastures...
  5. Are multi‐paddock grazing systems economically justifiable?

    Item type: Journal Article • Journal: Journal of the Grassland Society of Southern Africa
    The financial implications of few‐ and multi‐paddock systems were modelled by a discounted cash flow analysis with the (discounted) present value as the dependent variable, and number of paddocks, farm run‐down time, time horizon and discount rate as the independent...
  6. An evaluation of the empirical basis for grazing management recommendations for rangeland in southern Africa

    Item type: Journal Article • Journal: Journal of the Grassland Society of Southern Africa
    Analysis of over 50 grazing experiments conducted in southern Africa does not support certain management recommendations. Furthermore, the conclusions of some experiments are questionable owing to poor experimental design or confirmation bias. Based on available evidence, it was concluded that...
  7. Towards optimum grazing management for sheep production on crownvetch (<em>Coronilla varia</em> L.)

    Item type: Journal Article • Journal: Journal of the Grassland Society of Southern Africa
    The performance of wether lambs on crownvetch (Coronilla varia L.) pasture was determined for three seasons under five grazing procedures. These included continuous grazing and rotational grazing with a 7‐day period‐of stay and periods‐of‐absence of 7, 21, 35 or 49...
  8. Comparative performance of tomato cultivars cultivated in two hydroponic production systems

    Comparative performance of tomato cultivars cultivated in two hydroponic production systems

    Item type: Journal Article • Journal: South African Journal of Plant and Soil
    Cultivar selection for different hydroponic production systems is an important management decision, potentially impacting the tomato grower’s profitability. Knowledge on the performance of tomato cultivars, in specific hydroponic systems (open-bag and closed system) under South African conditions, is still very...
  9. Effect of grazing frequency and intensity on <em>Lolium perenne</em> L. pastures under subtropical conditions: Herbage production

    Effect of grazing frequency and intensity on <em>Lolium perenne</em> L. pastures under subtropical conditions: Herbage production

    Item type: Journal Article • Journal: African Journal of Range & Forage Science
    The dry matter (DM) production of Lolium perenne (perennial ryegrass) pastures was evaluated under subtropical conditions for two years, under five combinations of grazing frequency and intensity, each applied in a rotational grazing system. Simulated continuous grazing (CG) was also...
  10. Effect of grazing frequency and intensity on <em>Lolium perenne</em> L. pastures under subtropical conditions: Herbage quality

    Effect of grazing frequency and intensity on <em>Lolium perenne</em> L. pastures under subtropical conditions: Herbage quality

    Item type: Journal Article • Journal: African Journal of Range & Forage Science
    The cellulase dry matter disappearance (CDMD) and herbage nitrogen (N) of Lolium perenne (perennial ryegrass) were evaluated for pastures grown under subtropical conditions for two years, under five combinations of grazing frequency and intensity, each applied in a rotational grazing...
