  1. Comparison of osmopriming and seed coating with calcium salts for green bean performance under field conditions. II. Stand establishment, chlorophyll fluorescence and yield

    Comparison of osmopriming and seed coating with calcium salts for green bean performance under field conditions. II. Stand establishment, chlorophyll fluorescence and yield

    Item type: Journal Article • Journal: South African Journal of Plant and Soil
    Seed coating is commonly used to supply fungicides and micronutrients to enhance seed quality. The primary reason for using mineral elements in seed priming is to regulate water absorption. Osmopriming and seed coating were compared for their effect on crop...
  2. Secondary succession in the Mopani veld of the Limpopo Valley, South Africa

    Secondary succession in the Mopani veld of the Limpopo Valley, South Africa

    Item type: Journal Article • Journal: African Journal of Range & Forage Science
    The long-term establishment sequences of the herbaceous and woody component of the Mopani veld of the Limpopo Valley were studied and documented. Based on vegetation surveys conducted at three enclosed sites at the Messina Experimental Farm during the period 1964...
  3. Genetic variation between ecotypic populations of <em>Chloris roxburghiana</em> grass detected through RAPD analysis

    Genetic variation between ecotypic populations of <em>Chloris roxburghiana</em> grass detected through RAPD analysis

    Item type: Journal Article • Journal: African Journal of Range & Forage Science
    Chloris roxburghiana is an important rangeland grass in Kenya. In some areas it has disappeared due to land degradation resulting from overgrazing and drought. Efforts to re-introduce the grass through re-seeding using seeds from research stations have had little success...
  4. Grass defoliation affecting survival and growth of seedlings <em>of Acacia karroo</em>, an encroaching species in southwestern Zimbabwe

    Grass defoliation affecting survival and growth of seedlings <em>of Acacia karroo</em>, an encroaching species in southwestern Zimbabwe

    Item type: Journal Article • Journal: African Journal of Range & Forage Science
    Two experiments were conducted, one in the field and the other in the greenhouse, to investigate the effects of the intensity and frequency of grass defoliation on the survival and growth of Acacia karroo seedlings. In the greenhouse, seedlings growing...
  5. Impact of tree crowns on grass quality and structure in a semi‐arid rangeland in southwestern Zimbabwe

    Impact of tree crowns on grass quality and structure in a semi‐arid rangeland in southwestern Zimbabwe

    Item type: Journal Article • Journal: African Journal of Range & Forage Science
    Understory areas in semi‐arid rangelands can be a habitat for high‐yielding palatable grasses. Selective grazing of these grasses can result in their replacement by less palatable grass species, normally found in open areas. An experiment, at Matopos Research Station, sought...
  6. Nodulation potential of four <em>Trifolium repens</em> cultivars under field conditions

    Nodulation potential of four <em>Trifolium repens</em> cultivars under field conditions

    Item type: Journal Article • Journal: African Journal of Range & Forage Science
    Four Trifolium repens (white clover) cultivars were evaluated under field conditions to determine the potential of these cultivars to sucessfully develop Rhizobium-associated root nodules. Nodulation of T. repens is often poor, because of suboptimal environmental conditions or absence of host-specific...
  7. Precision forestry for pulpwood re-establishment silviculture

    Precision forestry for pulpwood re-establishment silviculture

    Item type: Journal Article • Journal: The Southern African Forestry Journal
    The Southern African pulp and paper industry has a strong export focus and operates in an open global market. In a global context, wood is a commodity product and an ongoing strategy of reduction in the unit cost of timber...
  8. Post establishment survival of <em>Pinus patula</em> in Mpumalanga, one year after planting

    Post establishment survival of <em>Pinus patula</em> in Mpumalanga, one year after planting

    Item type: Journal Article • Journal: The Southern African Forestry Journal
    Recent evidence indicated that the pathogen Fusarium circinatum might be contributing significantly to post-planting mortality. Consequently, sixteen experimental sample plots, widely distributed over many localities in Mpumalanga, were established over two growing seasons to quantify the extent of pest and...
  9. Effects of temperature on <em>Pinus patula</em> seedlings growing in pots in a controlled environment

    Effects of temperature on <em>Pinus patula</em> seedlings growing in pots in a controlled environment

    Item type: Journal Article • Journal: The Southern African Forestry Journal
    The re-establishment of Pinus patula seedlings into sites with high harvesting residue (slash) loads can negatively affect the survival of these plants. Field trials have examined the role that insect pests and fungal diseases play in causing this phenomenon. Research...
  10. Low light availability affects leaf gas exchange, growth and survival of <em>Euterpe edulis</em> seedlings transplanted into the understory of an anthropic tropical rainforest

    Low light availability affects leaf gas exchange, growth and survival of <em>Euterpe edulis</em> seedlings transplanted into the understory of an anthropic tropical rainforest

    Item type: Journal Article • Journal: Southern Forests: a Journal of Forest Science
    Euterpe edulis Mart. (Arecaceae) is a threatened palm tree of the Brazilian Atlantic Rainforest understory with fundamental importance for the restoration of degraded forest environments. We assessed the leaf gas exchange, growth and survival of E. edulis seedlings transplanted at...
