    Agronomic and qualitative performance of some experimental Burley hybrids in Malawi

    CHAMANGO A.M.Z.; SIBANDE L.A.G.O.; MATEWELE M.
    Agricultural Research and Extension Trust (ARET), Lilongwe, Malawi
    Malawi mainly depends on tobacco for forex generation, with Burley as a major contributor. However, the country has a limited choice of high yielding and disease resistant varieties against a plethora of disease constraints, particularly root-knot...

    Forestry sustainability in the tobacco sector in Malawi: a community concern requiring community approaches

    OFESI H.K.T.; LIVIMBO S.S.
    Agricultural Research and Extension Trust (ARET), Lilongwe, Malawi
    Tobacco farmers depend heavily on tree resources for poles and firewood used in curing. Malawi tobacco farmers predominantly grow Burley tobacco which requires the least amount of tree resources per unit volume in comparison to dark-fired and...

    Bacterial wilt (Ralstonia solanacearum) resistant flue-cured hybrids - current Malawi situation

    SIBANDE L.A.G.O.; CHAMANGO A.M.Z.; MATEWERE M.; KHUMBANYIWA A.G.
    Agricultural Research and Extension Trust (ARET), Lilongwe, Malawi
    In Malawi, flue-cured tobacco production is negatively affected by both aerial and soil borne diseases. Bacterial wilt (Ralstonia solanacearum) is one of the major soil borne diseases that attack the crop, reducing cured leaf yield and quality....

    Developing flue-cured tobacco hybrids with combined resistance to granville wilt and root-knot nematodes and angular leaf spot in Malawi

    SIBANDE L.A.G.O.; CHAMANGO A.M.Z.; GOMONDA R.W.J.
    Agricultural Research and Extension Trust (ARET), Lilongwe, Malawi
    Flue-cured tobacco production in Malawi is constrained by both soil-borne (root-knot nematodes and Granville wilt) and aerial borne (angular leaf spot and alternaria brown spot) diseases. To address these multiple challenges, a breeding programme was...

    Burley tobacco has variable levels of conversion of nicotine to nornicotine, the precursor for the main Burley tobacco specific nitrosamine (TSNA), N’-nitrosonornicotine (NNN). Malawian tobacco is inherently low in TSNA levels, affording a...

    Breeding for disease resistant dark-fire-cured tobacco in Malawi

    CHAMANGO A.M.Z.; GOMONDA R.W.J.; MAINJENI C.E.D.; MSANGOSOKO K.R.; KHUMBANYIWA A.G.; KASANGA T.
    Agricultural Research and Extension Trust (ARET), Lilongwe, Malawi
    Dark fire-cured tobacco (DFC) is the third most important tobacco type grown in Malawi after Burley and flue-cured. With Malawi Western, MW 86-57 and AWL 28 as the leading approved DFC varieties for production in Malawi, the local and regional...

    Potential of Jatropha seedcake for control of root-knot nematodes (Meloidogyne spp.) in tobacco

    MAINJENI C.E.D.; DUMBO E.L.C.; KWENDA H.A.B; MTONGA Y.P.
    Agricultural Research and Extension Trust (ARET), Lilongwe, Malawi
    Jatropha seedcake is reported to be efficient in the control of root-knot nematodes (Meloidogyne spp.) in crops such as tomato. In this study, five application rates of Jatropha seedcake were explored for control of nematodes in tobacco seedbeds....

    Evaluation of the effect of Jatropha seedcake as organic basal fertiliser on plant growth, yield and quality of flue-cured tobacco

    MTONGA Y.P.; MUMBA J.B.; GOMONDA R.W.J.
    Agricultural Research and Extension Trust (ARET), Lilongwe, Malawi
    Declining soil fertility and increased cost of inorganic fertilisers are a major constraint in tobacco production in Malawi. Cheaper and effective sources of nutrients would reduce the cost and improve the profit margins for tobacco. Jatropha is a...
