Apot experiment was conducted to determine the effect of zinc and nitrogen on growth, nodulation pattern and yield of cowpea. The treatments were four levels of nitrogen (0, 10, 20 and 30 kg/ha) and four levels of zinc (0, 5, 10 and 15 kg/ha). Application of various levels of nitrogen significantly increased dry matter production/plant, plant height number of branches/plant, effective nodules/plant, total nodule/plant, effective nodules weight/plant, pods/plant, seeds/pod and grain yield. Similarly zinc significantly increased plant height, branches/plant, number of leaves/plant, dry matter/plant, effective nodules weight/plant and grain yield. There was no significant interaction between nitrogen and zinc on grain yield.
