  1. Nitrogen fixation of annual temperate clover species determined by the nitrogen difference method

    Item type: Journal Article • Journal: Journal of the Grassland Society of Southern Africa
    The nitrogen fixation ability of Trifolium vesiculosum cv. Amclo and Trifolium subterraneum cv. Mount Barker in pure and mixed stands with Lolium multiflorum cv. Midmar were compared using the nitrogen difference method (NDM). The percentage and quantity of apparent legume‐derived...
  2. Eight decades of pasture plant improvement in South Africa

    Item type: Journal Article • Journal: Journal of the Grassland Society of Southern Africa
    Pasture plant improvement in South Africa is reviewed. Before 1910 only introduction and evaluation took place but shortly after 1910 selections were made from tall fescue introductions. Early breeding programmes were established at Prinshof, Potchefstroom, Grahamstown and later Rietondale.
  3. Growth patterns of Italian ryegrass cultivars established in different seasons

    Item type: Journal Article • Journal: Journal of the Grassland Society of Southern Africa
    A comparison is made between various Italian ryegrass cultivars established under irrigation on a well‐drained upland site during the traditional autumn months, with plantings of the same cultivars at other times of the year.
  4. The characterization of irrigated Midmar Italian ryegrass in the South Eastern Transvaal Highveld using slaughter lambs

    Item type: Journal Article • Journal: Journal of the Grassland Society of Southern Africa
    Four levels of available dry matter (DM) were maintained on a continuously grazed irrigated Midmar Italian ryegrass (Lolium multiflorum Lam.) pasture by means of a “put‐and‐take” grazing procedure. The pasture was stocked with three successive sets of weaned lambs in...
  5. Response of lambs to continuous and rotational grazing at four grazing intensities on Midmar Italian ryegrass

    Item type: Journal Article • Journal: Journal of the Grassland Society of Southern Africa
    Irrigated Midmar Italian ryegrass (Lolium multiflorum Lam.) was grazed either continuously or rotationally at four grazing intensities by three successive sets of weaned lambs for the winter, spring and summer periods, respectively. The “put‐and‐take” system was applied. In the case...
  6. Identification of companion small grains for midmar Italian ryegrass

    Item type: Journal Article • Journal: Journal of the Grassland Society of Southern Africa
    In a preliminary investigation four small grain species, oats (Avena sativa), rye (Secalae cereale), wheat (Triticum aestivum) and triticale (Triticum × secalae) were planted alone and in combination with Lolium multiflorum cv Midmar under irrigation. The dry matter (DM) yield...
  7. The response of Italian ryegrass to applied nitrogen in the natal midlands

    Item type: Journal Article • Journal: Journal of the Grassland Society of Southern Africa
    Nitrogen (N) fertilizer was applied to irrigated Italian ryegrass (Lolium multiflorum cv Midmar) pastures at varying rates over two seasons on three sites. Soils series on these sites were Metz, Griffin and Katspruit. Total N application rates ranged from zero...
  8. The production of four ryegrass cultivars oversown at various seeding rates into irrigated kikuyu

    Item type: Journal Article • Journal: Journal of the Grassland Society of Southern Africa
    An irrigated kikuyu pasture was oversown, in late March, with four ryegrass cultivars at four seeding rates at Cedara (Natal Mistbelt) and n'Tabamhlope (Highland Sourveld). The oversowing procedure shows promise with the cultivars producing well at both sites. There were...
  9. A preliminary survey of viruses in pasture grasses in South Africa

    Item type: Journal Article • Journal: Journal of the Grassland Society of Southern Africa
    Little work has been done in South Africa on the incidence of viruses in pasture grasses. The aim of this work was to carry out a survey of virus infections of some of the economically‐important pasture grasses in South Africa...
  10. An evaluation of the problem of volunteer ryegrass in seed production

    An evaluation of the problem of volunteer ryegrass in seed production

    Item type: Journal Article • Journal: South African Journal of Plant and Soil
    This investigation was conducted to establish the degree and means of eliminating unwanted volunteers of Lolium multiflorum from fields used for seed production of a cultivar of the same species. This information is necessary in order to make recommendations with...
