    Effect of priming as a practice for improving yield and quality of flue-cured tobacco in Malawi

    MTONGA Y.P.; MUMBA J.B.; GOMONDA R.W.J.
    Agricultural Research and Extension Trust (ARET), Lilongwe, Malawi
    Priming of leaves improves yield and quality of flue-cured tobacco. A field experiment was conducted at three locations in Malawi during the 2013 to 2016 cropping seasons. The aim was to investigate the effect of priming bottom leaves on yield and...

    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...

    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...

    Scout based application and integration of nematode resistant cultivars: an IPM strategy for reducing pesticide use in tobacco production in Malawi

    MSANGOSOKO K.R.; MAINJENI C.E.D.; GOMONDA R.W.J.; CHAMANGO A.M.Z.
    Agricultural Research and Extension Trust (ARET), Lilongwe, Malawi
    Tobacco production in Malawi faces serious pest problems such as the tobacco aphid (M. persicae) and root-knot nematodes (Meloidogyne spp.). A considerable amount of pesticides are used by growers to protect tobacco from yield and quality losses...

    The Integrated Tobacco Production System (IPS) model: opportunities, challenges and future prospects for Malawi

    MANTCHOMBE M.K.; MSANGOSOKO K.R.; CHAMANGO A.M.Z.; GOMONDA R.W.J.; KHUMBANYIWA A.G.
    Agricultural Research and Extension Trust (ARET), Lilongwe, Malawi
    For almost two decades, ARET has been the major player in providing research and extension services aimed at improving tobacco productivity in Malawi. However, there has been a paradigm shift following introduction of the Integrated Production System...
