    Effect of water regime and nitrogen fertilisation on growth dynamics, water status and yield of Burley tobacco (Nicotiana tabacum L.)

    RUGGIERO C.; ANGELINO G.; ASCIONE S.
    University of Naples ''Federico II'', Dept. of Agricultural Engineering and Agronomy, Portici, Naples, Italy.
    The results of a two-year research project into burley tobacco are reported and discussed. Three irrigation levels (40, 80 and 120% restitution of evapotranspiration (ET)) were factorially combined with four levels of nitrogen fertilisation (0, 80, 160 ...
