Abstract

Greenhouse and field experiments were conducted to evaluate the response of okra to different levels of human urine (0, 10,000, 15,000 and 20,000L/ha) and 400kg/ha NPK 15:15:15 inorganic fertilizer in five riverine communities of Cross River State, Nigeria. The soils of the communities are generally acid with low organic matter, total nitrogen, exchangeable cations, but were rated medium in available P. The pH of the urine was alkaline with moderate amount of nutrients. There was a significant (P<0.05) increase in nutrient uptake with application of either urine or inorganic fertilizer compared with the control. Application level of 20,000L urine/ha significantly increased the growth and yield attributes of okra plants relative to NPK fertilizer, while 15,000L urine/ha had a similar effect on okra plant as the inorganic fertilizer. The inert potentials of human urine as a good source of organic fertilizer are discussed.
