The social, socio‐demographic, socio‐economie, socio‐psychological, communication and agricultural production characteristics of...
  3. Changes in chemical properties and temperature during the degradation of organic wastes subjected to simple composting protocols suitable for small-scale farming, and quality of the mature compost

    Changes in chemical properties and temperature during the degradation of organic wastes subjected to simple composting protocols suitable for small-scale farming, and quality of the mature compost

    Item type: Journal Article • Journal: South African Journal of Plant and Soil
    Despite the high cost of chemical fertilizers and pesticides, composting is not widely practiced in many rural communities in South Africa. To demonstrate the simplicity and benefit of composting, four composting protocols were selected, based on technology and resources available...

    The relative abundance of maize stem borers and their parasitoids at the Tshiombo irrigation scheme in Venda, South Africa

    Item type: Journal Article • Journal: South African Journal of Plant and Soil
    Maize is an important resource in many small-scale farming areas in South Africa and especially on irrigation schemes in the Limpopo Province where this crop is cultivated under irrigation in sub-tropical conditions. The aim of this study was to determine...
  5. Biomass production, weed suppression, nitrogen and phosphorus uptake in white oat (<em>Avena sativa</em> L.) and grazing vetch (<em>Vicia dasycarpa</em> L.) cover crop bicultures under an irrigated no-till system

    Biomass production, weed suppression, nitrogen and phosphorus uptake in white oat (<em>Avena sativa</em> L.) and grazing vetch (<em>Vicia dasycarpa</em> L.) cover crop bicultures under an irrigated no-till system

    Item type: Journal Article • Journal: South African Journal of Plant and Soil
    Cultivation of a multipurpose cover crop is of interest to Eastern Cape farmers experiencing soil infertility and weed pressures. The objective of the study was to investigate effects of oat–vetch bicultures on biomass production, weed suppression, and nitrogen (N) and...
