Quinoa (Chenopodium quinoa Wild.), an ancient pseudo-cereal native to the Andean highlands, has emerged as a promising crop for sustainable agriculture due to its exceptional nutritional qualities and adaptability to stress conditions. Quinoa contains all nine essential amino acids, with protein content ranging from 14-18%, significantly higher than most cereals. Globally, quinoa production has increased from 80,000 tonnes in 2009 to over 200,000 tonnes in 2023, indicating rising demand. Its ability to thrive in drought-prone, saline, and marginal soils makes it ideal for climate-resilient farming, particularly in arid and semi-arid regions. In India, pilot projects in Rajasthan and Gujarat have shown yields of 8-12 quintals/ha under low-input conditions. Despite this potential, challenges such as limited agronomic knowledge outside South America, poor seed availability, and lack of established market chains persist. It also highlights opportunities including quinoa's ability to grow in saline and drought-prone soils, its suitability for organic and low-input farming systems, and its emerging role in food security and income generation for smallholder farmers. The study underscores the need for targeted research, policy support, and capacity-building initiatives to integrate quinoa into diversified and sustainable agricultural systems worldwide.
