    Effect of intercropping on crop productivity and quality of flue-cured tobacco in Malawi

    CHIPETA T.; MWALE H.; MAIDENI F.; CHANGAYA A.G.
    Agricultural Research and Extension Trust (ARET), Lilongwe, Malawi
    Limited land amidst growing population is one of the major constraints to producing more food and cash crops in Malawi. Intercropping has huge potential to utilize land more efficiently. A study was conducted to assess effects of intercropping...
