    Estimation of the state of nitrogen nourishment of tobacco using the N-tester

    KOWALCZYK-JUSKO A.; KOSCIK B.
    University of Agriculture, Lublin - Institute of Agricultural Sciences, Zamosc, Poland.
    The purpose of this work, based on a three years of field experiment, was to inspect whether it is possible to use a chlorophyll meter in fixing the nitrogen doses used in growing flue-cured tobacco. The relationship between the capacity of nitrogen...

    Influence of aqua terra hydrogel on growth, development and yield of light cigarette tobacco

    KOSCIK B.; KOWALCZYK-JUSKO A.
    University of Agriculture, Lublin - Institute of Agricultural Sciences, Zamosc, Poland.
    The aim of introductory field and pot experiments which were carried out in Zamosc in the years of 1995-1997 was to study the influence of Aqua Terra hydrogel on the growth, development and yield of light cigarette tobacco. Hydrogels are substances...
