Millets are one of the oldest food grains known to mankind. They are considered underutilized crops and can sustain in harsh environments with limited water resources where other crops grow or yield poorly. Millets are very adaptable: they thrive in dry regions, on clay soils, in wet lowlands, or alluvial lands. Their root systems are powerful, able to descend very quickly to a great depth of soil to extract water and minerals, and thus have high adaptability to climate change, especially drought. Millets have a good nutritional profile along with good nutraceutical potential and thus can be considered a great crop for combating food nutritional security globally.
