  1. Assessment of sweetpotato farming systems, production constraints and breeding priorities in eastern Tanzania

    Assessment of sweetpotato farming systems, production constraints and breeding priorities in eastern Tanzania

    Item type: Journal Article • Journal: South African Journal of Plant and Soil
    Sweetpotato is an important food security crop in Tanzania. The crop is grown under diverse farming systems with very low yields. The objective of this study was to assess the present sweetpotato farming systems, farmers’ preferences, production constraints and breeding...
  2. Assessment of genetic diversity of rice based on SNP markers for selection of parents for sheath rot (<em>Sarocladium oryzae</em>) resistance breeding

    Assessment of genetic diversity of rice based on SNP markers for selection of parents for sheath rot (<em>Sarocladium oryzae</em>) resistance breeding

    Item type: Journal Article • Journal: South African Journal of Plant and Soil
    Sheath rot of rice, caused by Sarocladium oryzae, is an important emerging rice disease not only in Rwanda, but also in other rice-growing countries. Given that cultivar resistance is a sustainable management strategy for small-scale farmers, the aim of this...
  3. Weed density and biomass are reduced and plant growth and seed yield increased in common bean after solarisation with clear and black plastic

    Weed density and biomass are reduced and plant growth and seed yield increased in common bean after solarisation with clear and black plastic

    Item type: Journal Article • Journal: South African Journal of Plant and Soil
    Common bean is highly sensitive to early weed competition, which severely reduces growth and yield. An experiment was carried out in Zimbabwe in the 2002/03 and 2003/04 seasons to assess the effectiveness of solarisation in controlling weeds in beans. Four...
  4. Phenotypic characterisation of potato (<em>Solanum tuberosum</em>) genotypes in Uganda

    Phenotypic characterisation of potato (<em>Solanum tuberosum</em>) genotypes in Uganda

    Item type: Journal Article • Journal: South African Journal of Plant and Soil
    Identification of genetic variation and interrelationships among germplasm collections is essential for parental selection and trait identification among parents for use in breeding programmes. The aim of this study was to characterise 48 potato genotypes to identify suitable parents for...

    Why HIV/AIDS should be treated as exceptional: arguments from sub-Saharan Africa and Eastern Europe

    Item type: Journal Article • Journal: African Journal of AIDS Research
    The idea that HIV and AIDS gets too much attention and funding emerged in 2008 with a call to end 'AIDS exceptionalism.' This article outlines a short history of AIDS exceptionalism — the idea that HIV and AIDS require a...
