Millets are small-seeded grasses that are hardy and grow well in dry zones as rain-fed crops under marginal conditions of soil fertility and moisture. They are possibly the first cereal grain to be used for domestic purposes comprising two main groups, major millets (sorghum and pearl millet) and minor millets (finger millet, kodo millet, foxtail millet, little millet, proso millet and barnyard millet). Millets are among the oldest cultivated crops in the world and cultivated over more than 35.8 million ha around the world. They are generally considered as ‘coarse’ cereals. They are the rich source of proteins, minerals, anti-oxidants and vitamins compared to major cereals like rice and wheat. Most of them controls diabetes, helps in weight loss, cures cancer, improves digestion. Millets grow under a wide range of day lengths and in poor soil, making them an attractive crop for marginal farming environments. They are known for their climate- resilient features including adaptation to a wide range of ecological conditions, less irrigation requirements, better growth and productivity in low nutrient input conditions, less resilience on synthetic fertilizers, and minimum vulnerability to environmental stresses unlike the major cereals. Known as C4 crops, millets have higher efficiency in absorbing and utilizing carbon dioxide. India ranked 102nd position in Global Hunger Index out of 117 countries which indicates the level of malnutrition in the country. And as the country is badly experiencing the effect of climate change, it is important to have millets on farm.
