Abstract
We conducted a greenhouse experiment, at Haryana Agricultural University, to learn the effects of N and Zn levels on concentration and uptake of P, K, Fe, Mn, and Cu in pearl millet (Pennisetum americanum). Applying 200 ppm N produced an antagonistic relationship on the concentration of P and K in leaves, stems, and roots and also on Fe and Cu concentrations in stems. We observed 42.6, 25.9, and 59.3% reductions in P concentrations in leaves, stems, and roots; also concentrations of Fe and Cu in stems decreased by 19.7 and 42.3%. Nitrogen increased the concentrations of Fe in leaves and roots, Cu in leaves, and Mn in leaves and stems. The effect of Zn on the concentrations of P and K in all plant parts was antagonistic. Zinc had a synergistic effect on the concentrations of Fe and Mn in leaves, stems, and roots up to 10 ppm Zn, and an antagonistic effect at 20 ppm Zn. However, the concentration of Cu and Zn had no effect on Cu contents of stems and roots. N × Zn interactions on the concentrations of P, K, and Fe in roots, Cu in leaves, and the uptake of P, K, Fe, Mn, and Cu in different plant parts of pearl millet were found to be significant.
