Effect of nitrogen fertilizer forms on some characteristics of flue-cured tobacco

, : Effect of nitrogen fertilizer forms on some characteristics of flue-cured tobacco. Revista de Ciencias Agrarias 18(2): 69-76

Field studies were performed over three years on flue-cured tobacco to compare the effect of nitrogen forms applied on the soil (100% nitrate, 50% nitrate-50% ammonium, 100% ammonium) on production, evaluation index, total nitrogen, total ammonium nitrate, total alkaloids, secondary alkaloids, and pH of produced leaves. No significant correlations were found between the forms of applied nitrogen and the studied factors. The effect of pulverization with vitamins inhibiting nitrosamine formation was simultaneously studied.
