The varieties were not equally responsive to Zn addition. Except BARI Hybrid Maize-3, all other hybrids showed higher response to Zn compared to composite varieties. Among the hybrids, the Pacific 984 had the highest response followed by BARI Hybrid Maize-1 and BARI Hybrid Maize Top 1, the later two showed identical response. Comparing the composite varieties, their response can be ranked as Barnali &asymp; Mohor &gt; Khoibhutta &gt; BARI Maize-6. The result suggests that BARI Hybrid Maize-3 and BARI Maize-6 were the most Zn inresponsive (Zn efficient) varieties. Further it appeared that Pacific 984 gave the highest seed yield, 10.46 t/ha due to Zn application. So, the farmers can grow this variety with an application of Zn @ 3 kg/ha in the deficient soil. The results also indicate that the farmers can cultivate BARI Hybrid Maize-3 in the moderately zinc deficient soils with a minimum dose (1 to 2 kg/ha) of Zn fertilization.</p> <p><strong>Keywords:</strong> Maize varieties; zinc fertilization.</p> <p>DOI: <a href="http://dx.doi.org/10.3329/bjar.v36i3.9272">http://dx.doi.org/10.3329/bjar.v36i3.9272</a></p> <p><em>BJAR </em>2011; 36(3): 437-447</p> ER -
