Abstract

Millets are multipurpose crops that can grow in diverse climatic conditions and have high nutritional value. However, the nutritional importance and various climatic adaptability of millets are not well recognized. The current review emphasizes the response of millet to climate variability, the significance of value-added products, and the role of millet agro residues. This review paper is a summary of a total of 106 published articles from different database sources. The results revealed that millets are a high source of protein, fat, minerals, and dietary fiber and rich in micronutrients which are used to overcome malnutrition and non-communicable diseases. Foxtail millet uses 257 g of water to produce 1 g of dry biomass as compared to maize (470g) and wheat (510g) indicating its climate resilience. The study also indicates a potential possibility of utilization of millet biomass in the production of bioenergy which in turn promotes the sustainability of renewable energy. Hence, developing schemes such as distributing seeds, fertilizer, pesticides, subsidized credit facilities, and promoting various value-added products are the main options to promote millet for further cultivation and consumption.
