Rice production in India is an important part of the national economy. It is a choice crop for millions of poor and small farmers not only for income but also for household food purpose. There is a gradual decline in availability of fresh water to be used for irrigation in India. As a consequence, the use of sewage and other industrial effluents for irrigating agricultural lands is rising, particularly in peri-urban areas of India. Hence, a case study was undertaken to analyse the cost- benefit ratio of rice yield in a sewage irrigated and rain fed and pond water irrigated rice agroecosystem in Western Odisha, India.
Use of the domestic wastewater with minimal fertilizers has shown improvement in the physico-chemical properties of the soil, crop yield and also in the nutrient status as compared to that of the paddy fields receiving pond water for irrigation along with the use of recommended dose of fertilizer. The cost benefit analysis indicated higher auxiliary energy input in site I (pond water irrigated plot) in comparison to site II where sufficient amount of nutrients from sewage were fed to the crops. The benefit for the farmers practising sewage fed irrigation was found to be nearly twofold when compared to the farmers practising pond water irrigation. The present case study gives emphasis on use of domestic water irrigation for grater rice yield and improvement of economic status of the poor farmers of India.
