The effect of N, P, and K fertilization on the mineral composition of tobacco leaves ( Nicotiana tabacum L.) was evaluated under field conditions for three cropping seasons. The amounts of added N, P, and K had a highly significant effect on the leaf concentrations of Ca, Mg, B, Zn, Cu, Mn, and Al and a significant effect on Fe concentration. Correlations between the concentrations of N, P, and K in the leaves and concentrations of the other mineral components of the leaf were similar to those for added N, P, and K. Nitrogen had a direct effect on Mg and Mn and an inverse effect on B concentrations in the tobacco leaves. Phosphorus had a direct effect on Ca, Mg, and B and an inverse effect on Zn and Cu. Potassium had an inverse effect on Ca, Mg, B, Zn, and Cu. Although not all coefficients were significant, K was inversely correlated to all eight mineral elements.
