The recent approach is to go for productive sanitation technology to achieve food security. Ecosan systems that produce a safe human derived liquid fertilizer can potentially contribute to improvement in quality of life and life expectancy by enabling sustainable food production as well as proper waste water management. In this context, field experiments were conducted in farmers' fields at Nagasandra village, Doddaballapura Tq, Bangalore district for one year to study the source separated human urine as a source of nutrients for banana cultivation (Musa paradisica) to meet the nitrogen requirement of this crop. The treatments were absolute control, recommended dose of fertilizers, recommended dose of nitrogen through human urine with and without gypsum and fertilizer applied to soil and different combinations of human urine and fertilizers. The results of the field experiment revealed that the highest bunch yield (30.0 t ha-1) of banana was recorded in the treatment which received RDN through human urine (After 30 days of planting) + Gypsum applied to soil when compared to control, and other treatment combinations. The available nutrients content of harvest soil viz., N, P and K had significant influence on it. Significant increase in the nitrogen, phosphorus and potassium content of plant samples was observed in the crop. The highest total soluble solids (25.85 percent), reducing sugars (20.93 percent) and total sugars (23.87 percent) were recorded in banana grown using human urine. The outcome of the present investigation revealed that Ecosan system helps to provide better sanitation, help farmers to save the cost on fertilizers without affecting the crop yields and thus help to achieve food security.
