Other claims from this paper (11)
- Association Grain and biomass yields of maize increased significantly as tillage frequency rose from zero to four in both seasons.
- Association Grain and biomass yields of soybean increased significantly as tillage frequency rose from zero to four in both seasons.
- Intervention effect Land equivalent ratio of maize-soybean intercropping was significantly higher than sole cropping in all tillage frequencies and both seasons (LER 1.87-2.12).
- Intervention effect Two tillages with maize-soybean intercropping gave 126% greater net benefit than four tillages with sole maize.
- Association Net benefit of maize was strongly influenced by the main effects of tillage and intercropping and by their interaction in 2014 (p<0.05).
- Intervention effect Reducing sole maize tillages from four to two gave a marginal rate of return of 705% under irrigated conditions relative to zero-tillage sole maize.
- Intervention effect Reducing tillage frequency from four to two in maize-soybean intercropping gave a marginal rate of return of 608% relative to zero-tillage intercropping.
- Intervention effect Reducing tillage frequency from four to two in maize-soybean intercropping gave a marginal rate of return of 585% relative to zero-tillage intercropping.
- Recommendation The authors suggest two alternative options for farmers in the drylands of Tigray: sole maize with reduced tillage or maize-soybean intercropping with reduced tillage.
- Recommendation Two tillages combined with maize-soybean intercropping can be a good option in Tigray drylands for higher total intercrop yield at low cost and larger LER.
- Recommendation Reduced tillage can minimize soil degradation and benefit farmers with poor access to draft power or labour for ploughing.
