Intercropping tef and sunflower in semi‐arid areas of Welo, Ethiopia

The productivity of tef-sunflower intercropping, with or without fertilizer, was assessed by field trials in northeast Ethiopia. Mixed planting of 10–50% of sunflower with tef had yield advantages of 20–39% and 58–77% at two different sites. The crop proportions giving the greatest yield benefit varied between the sites. The greatest net income benefits were US$515 ha−1 and US$69 ha−1 at the two sites. Copyright © 2006 John Wiley & Sons, Ltd
