Figure 1

(a) The nitrogen (N), (b) phosphorous (P) and (c) potassium (K) content of maize seedlings affected by the application of various doses (0, 15, 30 and 45 kg ha−1) of sulfate fertilizers (K2SO4, FeSO4, CuSO4 and Na2SO4). The mean values with different letters indicate significant difference (P ≤ 0.05), according to post hoc Tukey’s test.
