    Polypot system: a cost saving practice for improved tobacco seedling quality in Malawi

    MTONGA Y.P.; MUMBA J.B.; GOMONDA R.W.J.
    Agricultural Research and Extension Trust (ARET), Lilongwe, Malawi
    This trial investigated a tobacco seedling production system known as the Polypot which is a slight variant of the Motherbed. It aimed to evaluate the effectiveness, benefits and challenges of the Polypot in relation to the other seedling production ...

    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 controls ...

    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 tree of ...
