  1. Assessing legumes indigenous to South Africa, Lesotho and Swaziland for their pasture potential

    Assessing legumes indigenous to South Africa, Lesotho and Swaziland for their pasture potential

    Item type: Journal Article • Journal: African Journal of Range & Forage Science
    In contrast to the exploration and use of southern African grass plant genetic resources over the past century, only a few indigenous legume species are currently used as forages, notwithstanding the vast untapped legume diversity available in southern Africa. The...
  2. Effect of nitrogen application, seeding rate and defoliation height on mixtures of <em>Trifolium vesiculosum</em> cv Amclo and <em>Lolium multiflorum</em> cv Midmar: I. dry matter production, crude protein content and crude protein production*

    Item type: Journal Article • Journal: Journal of the Grassland Society of Southern Africa
    The interaction between Trifolium vesiculosum cv Amclo and Lolium multiflorum cv Midmar was measured in a field trial, in terms of dry matter production, crude protein content and crude protein production. The treatments included in the field trials were five...
  3. Effect of nitrogen application, seeding rate and defoliation height on mixtures of <em>Trifolium vesiculosum</em> cv Amclo and <em>Lolium Multiflorum</em> cv midmar: II. Yield advantage as reflected in the land equivalent ratio*

    Item type: Journal Article • Journal: Journal of the Grassland Society of Southern Africa
    Pure stands of Trifolium vesiculosum cv Amclo and Lolium multiflorum cv Midmar were compared with a range of mixtures of these two species in terms of dry matter production, crude protein content and crude protein production. Land equivalent ratios (LER)...
  4. Plant relations in mixtures of <em>trifolium subterraneum</em> cv mt barker and <em>loliumm ultiflorum</em> cv Midmar: I. dry matter production, crude protein content and crude protein production

    Item type: Journal Article • Journal: Journal of the Grassland Society of Southern Africa
    The interaction between Trifolium subterraneum cv Mt Barker and Lolium multiflorum cv Midmar was measured in a field trial in terms of dry matter production, crude protein content and crude protein production. The treatments included five different seeding rates of...
  5. Comparative response of lucerne (<em>Medicago sativa</em> L.) and sainfoin (<em>Onobrychis viciaefolia</em> Scop.) to applications of P, K and lime

    Comparative response of lucerne (<em>Medicago sativa</em> L.) and sainfoin (<em>Onobrychis viciaefolia</em> Scop.) to applications of P, K and lime

    Item type: Journal Article • Journal: South African Journal of Plant and Soil
    A pot experiment and an irrigated field trial in which the response of sainfoin and lucerne to different levels of P, K and lime was compared, are described. The results of the pot experiment suggested a better response to lime...
  6. <em>Research Note:</em> The use of <em>Lolium multiflorum</em> and uninoculated <em>Trifolium subterraneum</em> as reference crops in nitrogen fixation studies

    <em>Research Note:</em> The use of <em>Lolium multiflorum</em> and uninoculated <em>Trifolium subterraneum</em> as reference crops in nitrogen fixation studies

    Item type: Journal Article • Journal: African Journal of Range & Forage Science
    The 15N natural abundance and15 N dilution methods were used to determine the viability of using either Lolium multiflorum (annual ryegrass) or uninoculated Trifolium subterraneum (subterranean clover), as non‐fixing reference crops in N2‐fixation studies. The δ13N values for the15 N...
  7. Production of irrigated <em>Trifolium repens</em> L. under a cutting regime in the subtropical region of Gauteng, South Africa

    Production of irrigated <em>Trifolium repens</em> L. under a cutting regime in the subtropical region of Gauteng, South Africa

    Item type: Journal Article • Journal: African Journal of Range & Forage Science
    The productivity of Trifolium repens L. cv. Ladino, under irrigation in the subtropical region of Gauteng, South Africa, is unknown. The performance of T. repens was determined over five years (1981/1982 to 1985/1986), at two defoliation frequencies, four levels of...
  8. Anti-epileptic prescribing patterns in the South African private health sector (2008–2013)

    Anti-epileptic prescribing patterns in the South African private health sector (2008–2013)

    Item type: Journal Article • Journal: South African Family Practice
    Background: Little is known about longitudinal prescribing practices for anti-epileptic drugs (AEDs) in South Africa. The prescribing patterns and associated direct medicine costs of AEDs in the private health sector were investigated, using claims data from January 1, 2008 to...
