    New locally-bred nematode resistant Burley tobacco hybrids for Malawi

    CHAMANGO A.M.Z.; GOMONDA R.W.J.; MAINJENI C.E.D.; MSANGOSOKO K.R.; KUMWENDA R.L.N.
    Agricultural Research and Extension Trust (ARET), Lilongwe, Malawi
    Burley tobacco is produced by over 200 000 farmers throughout Malawi. However, productivity losses caused by soil borne diseases, particularly root-knot nematodes (Meloidogyne spp.) remain a potential concern due to use of low yielding susceptible...

    Evaluation of effect of coated fertilisers for use in flue-cured tobacco production

    MTONGA Y.P.(1); MUMBA J.B.(1); GOMONDA R.W.J.(1); LOCKINGTON I.(2); MACMILLAN C.(2)
    (1) Agricultural Research and Extension Trust (ARET), Lilongwe, Malawi; (2) Greenbelt Fertilisers Ltd, Mazabuka, Zambia
    Two coatings, one which coats phosphate known as Avail and another called Nutrisphere-N which coats nitrogen, were used. Avail lengthened phosphate availability by protecting the phosphates from being locked up by Fe, Al, Mg and Ca. Nutrisphere-N...

    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...
