Manure is considered as one of the best organic nutrients that enhances the soil’s physio-chemical properties. Cow urine is believed to provide nutrient at low cost and can be considered as alternative for plant nutrition, metabolic activities, pest and disease control. The study was conducted to assess the soil quality and plant yield under the effect of different concentrations of fermented and non-fermented cow urine. Eight treatments with different concentrations (25%, 50%, 75%, 100%) of fermented and non-fermented cow urine was applied for the study of soil quality and crop productivity taking leguminous plant (Cowpea) as a indicator plant. The research was done within the premises of Kathmandu University. The result showed that the highest plant height was found in the treatment 75% ferment urine (105.4cm) and the lowest height was found in 100% ferment urine. The highest fruit yield was found in 25% unfermented urine and lowest was seen in 25% fermented urine. The research concluded that 25% urine application was good for the plant growth and crop yield.
The study was carried out by Nikita Pradhan and Pratiksha Koirala, students of Department of Environmental Science and Engineering, Kathmandu University in 2016.
