    Chemically topping Burley tobacco

    RICHMOND M.D.(1); PEARCE R.C.(1); BAILEY W.A.(2)
    (1) University of Kentucky, Department of Plant and Soil Sciences, Lexington, KY, U.S.A.; (2) University of Kentucky Research and Education Center, Princeton, KY, U.S.A.
    The act of topping tobacco (Nicotiana tabacum L.) involves the removal of the terminal bud or inflorescence of the tobacco plant. This practice ordinarily is accomplished by manually removing the top of each tobacco plant in an entire field, which is...

    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...
