  1. An examination of methods of sampling herbage from small‐plot cutting trials

    An examination of methods of sampling herbage from small‐plot cutting trials

    Three experiments were conducted to measure variability in sampling for dry matter and crude protein determination in small‐plot cutting trials.
  2. Some factors affecting germination and emergence of sub‐tropical pasture legumes in Rhodesia

    Some factors affecting germination and emergence of sub‐tropical pasture legumes in Rhodesia

    The effect of depth of seeding, moisture stress, shading and mulching on the emergency of a number of sub‐tropical pasture legumes was examined on two contrasting soil types in the greenhouse.
  3. Some factors affecting the field establishment of sub‐tropical pasture legumes in Rhodesia.

    Some factors affecting the field establishment of sub‐tropical pasture legumes in Rhodesia.

    The establishment of Stylosanthes guyanensis cv. Oxley (fine‐stem stylo) into reverted sandveld grassland and of Oxley stylo, Macroptilium atropurpureum cv. Siratro, Desmodium intortum, and D. uncinatum cv. Silverleaf in arable land, was studied in a series of field trials at...
  4. Mechanical scarification of <em>stylosanthes guianensis cv</em>. Oxley seed

    Mechanical scarification of <em>stylosanthes guianensis cv</em>. Oxley seed

    In a series of experiments, in‐pod seed of Stylosanthes guianemis cv. Oxley from various sources, containing high proportions of hard seed, was mechanically scarified either by abrasion or impact treatments, involving different machine speeds and numbers of passes through the...
  5. Genotypic variation in leaf water potential of field-grown soybeans (<em>Glycme max</em> L. Merr.) and its association with dryland yield

    Genotypic variation in leaf water potential of field-grown soybeans (<em>Glycme max</em> L. Merr.) and its association with dryland yield

    Item type: Journal Article • Journal: South African Journal of Plant and Soil
    Maintenance of leaf water potential (ΨL) during periods of water stress may constitute an important drought-avoiding response. The identification of genotypic variation for this characteristic is, however, made difficult by the fact that comparative values for ΨL must be measured...

    A cryptic species of <em>Mytilus</em> (Mollusca: Bivalvia) on the west coast of South Africa

    Item type: Journal Article • Journal: South African Journal of Marine Science
    A biochemical genetic study of the mussels Perna perna and Choromytilus meridionalis on the west coast of South Africa revealed the presence of an unreported mytilid mussel that had previously been mistaken, because of its shell colour polymorphism, for either...
