    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,...

    Growth and water relations of sun-cured tobacco irrigated with saline water

    ANGELINA G.; ASCIONE S.; RUGGIERO C.
    University of Naples ''Federico II'', Dept. of Agricultural Engineering and Agronomy, Portici, Naples, Italy.
    We have investigated the effects of saline irrigation on growth and water relations of two sun-cured tobacco genotypes, Xp102 and Px107, which belong to the Xanthia and Perustitza tobacco ecotypes, respectively. We compared three commercial sea salt...

    Effect of increasing NaCl in irrigation water on growth, physiology and yield of tobacco (Nicotiana tabacum L.), Burley type. A preliminary study

    SIFOLA M.I.; GAROFALO C.; POSTIGLIONE L.
    University of Naples ''Federico II'', Dept. of Agricultural Engineering and Agronomy, Portici, Naples, Italy.
    A field experiment was carried out at the Experimental Farm of the University of Naples (Sele River Plain, Southern Italy, 40° 49' N, 14° 21' E) during 1996 and 1997 on tobacco crop, Burley type. The experiment was located in a region (Campania) in...

    Effect of water deficit or water excess during the different development stages on tobacco"Burley"

    POSTIGLIONE L.; BARBIERI G.; DE FALCO E.
    University of Naples ''Federico II'', Dept. of Agricultural Engineering and Agronomy, Portici, Naples, Italy.
    A two-year experiment was carried out in the Sele river Plain (Southern Italy) in order to evaluate the effects of water deficit or water excess on the performance of"Burley C103". Nine irrigation treatments were compared : 1) non irrigated control...
