Influence of Human Urine on Rice Grain Yield (Orzya sativa L.) and Selected Soil Properties in Abakaliki Southeastern Nigeria

An experiment was carried out at Abakaliki Southeastern Nigeria to study the influence of human urine on rice grain yield, selected soil physical and chemical properties in Abakaliki southeastern Nigeria in 2014 and 2015. The experiment was arranged in randomized complete block designed (RCBD) with human urine applied in the following rates: A = Control (no application of treatment); B = 2 kilolitres/ha; C = 4 kilolitres/ha and D = 6 kilolitres/ha. Treatments were not applied in 2015 to test the residual effect. In general, human urine improved rice grain yield, bulk density, total porosity, hydraulic conductivity, moisture content, organic carbon, total nitrogen, C/N ratio, pH, available phosphorus and exchangeable bases in 2014 it was applied and the following year as residual effect. An increase in the rate of urine application also resulted to an increase in rice grain yield and higher improvement in soil properties studied.
