    Responses of flue-cured tobacco to the fertilisation of sulphur (SO4) in South Africa

    BOSHOFF H.J.
    Agricultural Research Council – Institute for Industrial Crops, Rustenburg, South Africa
    The objective of this study was to investigate the possible benefits of an increased supply of calcium on the yield, quality and chemical composition of flue-cured tobacco, specifically on soils that proportionally have a large amount of extractable ...

    Evaluation of host suitability for meloidogyne species of rotational crops used in tobacco cultivation in South Africa

    VAN BILJON E.R.
    ARC, Agricultural Research Council - Institute for Industrial Crops, Rustenburg, South Africa
    Crop rotation is the single most useful practice that can realistically be applied to annual and short- term perennial crops. It is also not uncommon for a single field to have several nematode species present that could have a limiting effect on a ...

    The use of biologically active rotation crop for the suppression of Ralstonia Solanacearum in soils used for tobacco production

    TERBLANCHE J.
    ARC, Agricultural Research Council - Institute for Industrial Crops, Rustenburg, South Africa
    Bacterial wilt, caused by Ralstonia solanacearum (Race 1), is probably the most important bacterial disease of tobacco. The purpose of this study was to identify crops, which aggressively suppress R. solanacearum (Race 1), in their rhizospheres by means ...

    Lowering the nicotine content of flue-cured tobacco cultivars in South Africa

    VAN TONDER C.S.M.; KRUGER J.; DIPPENAAR M.C.
    Tobacco and Cotton Research Institute, Soil and Crop Science Division, Rustenburg, South Africa
    The nicotine content of flue-cured tobacco produced in the RSA is determined by factors suchas soil fertility, climatic conditions and production practices. The nicotine content of the leaf cannot be reduced dramatically without a detrimental effect on ...
