Abstract: To research the yield and economic benefit of new planting patterns with sweetpotato in dryland, new double cropping planting pattern of broad bean-organic sweetpotato and traditional pattern of maize-wheat-sweetpotato(CK) were conducted in Xichong county, Nanchong city, Sichuan province. The results indicated that, compared with the local traditional patterns, the unprocessed food grain yield of new planting pattern of double cropping that broad bean-organic sweetpotato was decreased by 78.47%~84.08%, but the total output value of that were increased by 36.61%~49.46%, net output value of that were increased by 65.67%~87.38%, net benefits of that were increased by 3.64~4.64 times than control, agriculture labour net productivity of that were increased by 1.01~1.27 times. It can be seen that the new pattern of broad bean-organic sweetpotato has a good prospect in popularization and application in Xichong county and other similar regions.
