Annual intercrops: an alternative pathway for sustainable agriculture. (2011, background): “Regularly intercropped pigeonpea or cowpea can help to maintain maize yield to some extent when maize is grown without mineral fertilizer on sandy soils in sub-humid zones of Zimbabwe (Waddington et al., 2007).”
Maize-grain legume intercropping is an attractive option for ecological intensification that reduces climatic risk for smallholder farmers in central Mozambique (2012, methodology): “The initiative was based on known benefits of introducing legumes in maize-dominated cropping systems of southern Africa (Jeranyama et al., 2000; Giller, 2001; Snapp et al., 2003; Waddington et al., 2007).”
Comparative analysis of maize–soybean strip intercropping systems: a review (2018, background): “Several studies have shown the importance of cereal and legume intercropping system, which is considered as an old practice in tropical agriculture (Ghanbari et al., 2010; Tsubo et al., 2001; Waddington et al., 2007).”
