The challenge of producing enough food to match ever increasing population demands exploring and expanding frontiers of research. Thus, this experiment was carried out to study the effect of different sources of urine on soil chemical properties and maize yield. The experiment was arranged in completely randomized design (CRD) with four treatments of control (0 kgNha-1) and 100 kgNha-1 of human urine, cattle urine and goat urine. These treatments were replicated six times to give a total of twenty four experimental pots filled with 5 kg of soil each. The results obtained show that there was significantly (P<0.05) higher effect of different sources of urine on total nitrogen, available phosphorus and exchangeable Ca and Mg when compared with the Control. Similarly, significantly (P<0.05) higher total nitrogen was obtained under human and cattle urine treatments relative to goat urine treated pots. The results further show significant (P<0.05) differences among the different sources of urine in available phosphorus, exchangeable Ca and Mg. Organic carbon obtained in human urine treated pot was 22% each higher than the ones recorded in cattle and goat urine treated pots. There was no difference among the treatments in plant height. Significantly (P<0.05) higher maize grain yield was obtained in different sources of urine relative to the Control. Generally, human urine treatment produced taller plants (124.85 cm/pot) and gave higher yield of maize (60.2 g/pot) which were higher by 2, 8, 3, 4%; and 67, 53, 54% respectively, when compared with the Control. It is recommended that the experiment be further carried out at field trial to validate these findings.
