DLR systems generally had an impact on maize yields that was comparable
to traditional rotation systems. The sole exception was at
Lintipe, where maize yields in DLR systems were lower than traditional
rotations in better growing seasons.
Grain yields of soybean and groundnut were unaffected by
pigeonpea intercrops across the full range of sites and season (Fig. 3).
Stover production was much higher in DLR systems and maize/
pigeonpea intercrops than in other cropping systems (see supplementary
data Figure S1). The difference was particularly marked at Lintipe
and Kandeu, where pigeonpea biomass yields were relatively high,
and less pronounced at Golomoti where pigeonpea yields were lower
