Abstract: Nowadays, in a context of climate change, economical uncertainties and social pressure to mitigate agriculture externalities, farmers have to adopt new cropping systems to achieve a sustainable and cost-effective grain production. Conservation agriculture (CA) consists of a range of cropping systems based on a combination of three main principles: (1) minimum soil disturbance, (2) permanent soil cover through crop residues or cover crops, and (3) crop rotations for achieving higher productivity. CA has been promoted as a way to reduce production costs, soil erosion and soil fertility degradation under both tropical and temperate conditions. In India, efforts to develop, refine and disseminate conservation-based agricultural technologies have been underway for nearly two decades and made significant progress since then even though there are several constraints that affect adoption of CA. Particularly, tremendous efforts have been made on no-till in wheat under a rice-wheat rotation in the Indo-Gangetic plains. The technologies of CA provide opportunities to reduce the cost of production, save water and nutrients, increase yields, increase crop diversification, improve efficient use of resources, and benefit the environment. However, there are still constraints for promotion of CA technologies, such as lack of appropriate seeders especially for small and medium scale farmers, competition of crop residues between CA use and livestock feeding, burning of crop residues, availability of skilled and scientific manpower and overcoming the bias or mindset about tillage. The need to develop the policy frame and strategies is urgent to promote CA in the region. This paper reviews the emerging concerns due to continuous adoption of conventional agriculture systems, Benefits of conservation agriculture and analyses the constraints of conservation agriculture in India.
