Long-term conservation agriculture-based practices impact crop yields, returns and yield stability in rice-wheat rotations in eastern Indo-Gangetic Plains of India
South Asia’s rice-wheat system is a regionally unique and crucially important cropping system contributing to staple food production. Over a 16-year period, a comprehensive experimental study on the rice-wheat cropping system indicated that, while wheat yields demonstrated a gradual increase over time, rice yields largely reached a stable level across various management approaches.
