Abstract: Human urine contains high amount of nitrogen (N), Phosphorous (P) and potassium (K). The plant availability of N in urine is the same as that of synthetic chemical fertilizer (urea) or ammonium fertilizer. This paper reports the fertilizer value of human urine for cabbage and carrot cultivations under greenhouse conditions. Both vegetables were grown in a pot filled with agricultural soils and treated with synthetic chemical fertilizer (SCF) or Human Urine (HU). The double dose of fertilizers which added for the cultivation of cabbage and carrot were 360kgN/ha and 160kgN/ha respectively for both SCF and HU. In both cases controls were neither fertilized by SCF nor by HU. The microbial quality of the cultivated cabbage head and carrot root samples was also assessed. Results show that the yield and other measured agronomic parameters of both vegetables treated with urine were found to be higher than that of untreated vegetables. However, the effect of urine addition was found to be similar with that of SCF in most of the variables measured. There was no significant difference between treatments in hygienic quality of the edible portions of both vegetables. This suggests that urine can be used to fertilize cabbage and carrot with no negative impact on human health.
