A pot experiment was conducted in 2018 to assess the effects of zinc fertilization on dry matter yield and nutrients uptake of hybrid maize. The treatments consisted of three doses: 0.0, 2.5 and 5.0 kg Zn ha-1 as ZnSO4.7H2O and hybrid maize variety PAC-740 was as test crop arranged in a completely randomized block design (RCBD) with three replications. The soils were acidic in nature, EC were low, organic carbon in the soils were fairly high (mean 17.71 g kg-1) and the mean CEC of the soils was 16.36 [cmol(P+)kg-1]. All the collected soil samples were clay in textural class. The results showed the addition of Zn substantial differences in dry matter yield and nutrients uptake of hybrid maize. Positive and significant correlations were obtained between DTPA-Zn and Bray’s per cent yield (r=0.444*), dry matter yield in control (r=0.916**), Zn concentration in control (r=0.966**), Zn uptake in control (r=0.959**) and Bray’s per cent uptake (r=0.492*). The critical limits of Zn in soils and 45 days old maize plant was 0.88 mg kg-1 and 22 mg kg-1, respectively. The study concludes that, on the basis of critical limits in soil and maize plant, Zn fertilization may be carried out for economic yield.
