  1. A qualitative analysis of the barriers to antiretroviral therapy initiation among children 2 to 18 months of age in Swaziland

    A qualitative analysis of the barriers to antiretroviral therapy initiation among children 2 to 18 months of age in Swaziland

    Item type: Journal Article • Journal: African Journal of AIDS Research
    HIV/AIDS remains one of the leading causes of death among children under 5 years old in Swaziland. Although studies have shown that early initiation of infants and children diagnosed with HIV on antiretroviral therapy (ART) significantly reduces mortality, many children...
  2. 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...
  3. Response of subterranean clover to liming and phosphate fertilization on a low potassium soil

    Response of subterranean clover to liming and phosphate fertilization on a low potassium soil

    Item type: Journal Article • Journal: South African Journal of Plant and Soil
    Several Trifolium varieties grown in an acid Bokkeveld shale soil responded positively to small additions of lime and P. Growth was probably limited by a K deficiency, and it is unlikely that Trifolium species could be successfully grown as cover...
  4. Water use of maize in response to planting density and irrigation

    Water use of maize in response to planting density and irrigation

    Item type: Journal Article • Journal: South African Journal of Plant and Soil
    This study aimed to quantify the effect of plant population density and irrigation on the water use efficiency (q) of maize crops, with particular emphasis on the partitioning of water use into transpiration (T) and direct evaporation of water from...
  5. Predicting the effects of nitrogen and planting density on maize water use in semi-arid Kenya

    Predicting the effects of nitrogen and planting density on maize water use in semi-arid Kenya

    Item type: Journal Article • Journal: South African Journal of Plant and Soil
    Models are important tools to assess the scope of management effects on crop productivity under different climatic and soil regimes. Accordingly, this study developed and used a simple model to assess the effects of nitrogen fertiliser and planting density on...
  6. Recommendations for the management of subsistence fisheries in South Africa

    Recommendations for the management of subsistence fisheries in South Africa

    Item type: Journal Article • Journal: South African Journal of Marine Science
    This paper summarizes recommendations for the management of previously marginalized and neglected subsistence fisheries in South Africa. The recommendations stem from the activities and analyses of a task group appointed by Government and mandated to provide advice about management of...
  7. Perceptions of subsistence and informal fishers in South Africa regarding the management of living marine resources

    Perceptions of subsistence and informal fishers in South Africa regarding the management of living marine resources

    Item type: Journal Article • Journal: South African Journal of Marine Science
    Following the legal recognition of subsistence fishers in 1998 through the promulgation of the Marine Living Resources Act, a Subsistence Fisheries Task Group (SFTG) was appointed by national government to provide recommendations on the management of subsistence fishing in South...
  8. Identification of subsistence fishers, fishing areas, resource use and activities along the South African coast

    Identification of subsistence fishers, fishing areas, resource use and activities along the South African coast

    Item type: Journal Article • Journal: South African Journal of Marine Science
    A description is given of the research undertaken to provide a broad overview of the distribution and numbers of people who are subsistence or artisanal fishers and their activities along the coast of South Africa, to assist in the formulation...
  9. The process of developing a management system for subsistence fisheries in South Africa: recognizing and formalizing a marginalized fishing sector in South Africa

    The process of developing a management system for subsistence fisheries in South Africa: recognizing and formalizing a marginalized fishing sector in South Africa

    Item type: Journal Article • Journal: South African Journal of Marine Science
    Subsistence fishers were first recognized as a formal fishing sector in South Africa when new fishing legislation, aimed at redressing past inequalities, was enacted in 1998. Little information was available about these fishers, their activities, and the resources upon which...
  10. An assessment of the role of the sand shark <em>Rhinobatos annulatus</em> as a predator in Langebaan Lagoon

    An assessment of the role of the sand shark <em>Rhinobatos annulatus</em> as a predator in Langebaan Lagoon

    Item type: Journal Article • Journal: South African Journal of Marine Science
    The possible impact of predation on benthic invertebrates by the sand shark Rhinobatos annulatus in Langebaan Lagoon was investigated. Studies on the population dynamics and the feeding biology of the sand sharks indicated temporal and spatial changes in the intensity...
