Interactive effect of phosphorus (P) and copper (Cu) on maize growth was studied in pots. Phosphorus at a rate of 0, 25, 50 mg/kg and copper at a rate of 0, 2.5, 5 mg/kg were applied in all possible combinations to a sandy loam soil. Five plants of maize in each pot were grown to tussling stage which receive N and K at a rate of 75 and 50 mg/kg, respectively. Fresh and dry weight of maize fodder increased with the P and Cu application but decreased at their higher combinations. Nitrogen concentration was increased with Cu application whereas, P concentration decreased. Phosphorus application increased P concentration while decreased the Cu concentration in the maize plants, leading to conclude that an interaction between P and Cu in soil occur which affects the production of maize fodder significantly.
