Of the cereals grown in India, rice consumes the most water per tonne of output while delivering the least nutrients—iron, zinc and protein—according to the study published in Science Advances, a global science journal. The suggested replacements for rice are maize, finger millet, pearl millet and sorghum, all of which consume less water per tonne and are
