Currently, the world is confronting the dual challenge of ensuring food security and addressing nutritional deficiencies. While agricultural production in irrigated lands has reached its maximum capacity, there is a pressing need to shift focus towards dry lands in order to increase grain production. However, the low fertility of these arid regions possesses a significant obstacle in producing an adequate quantity of high-quality grains. Millets, as crops that are resilient to climate change, offer a distinct advantage over other grains such as wheat and rice, as they possess the ability to thrive in marginal conditions while providing excellent nutrition. The plentiful presence of vitamins, minerals, essential fatty acids, phytochemicals, and antioxidants in these nutritious cereals, making them highly effective in addressing diseases resulting from nutritional deficiencies. Cultivating millets not only helps sustain the productivity of arid lands but also guarantees food and nutritional security for the future.
