Abstract

                                Improved agricultural practices that increase yields and preserve soils are critical to addressing food insecurity and undernutrition among smallholder farmer families. Human urine has been shown to be an accessible and effective fertilization option in various countries. Field experiments were conducted at the University of Agricultural Science, GKVk, Bangalore farm on Finger millet and Brinjal crops as the test crops in succession for 2 consecutive years in the same field. Different treatment combinations tried include human urine, with and without gypsum, cattle urine Farm Yard Manure (FYM), chemical fertilizers and control. The fertilizer value of human urine was assessed and supplied to the crops based on the nutrient content. The results revealed that the yield of two crops was significantly higher in treatment receiving human urine + FYM followed by human urine alone. Generally the results showed that human urine performed well than the commercially available chemical fertilizers (urea) applied as a source of N for crops and does not pose any significant hygienic threats and leave any significant flavor in food products.
