In tropical agriculture, maize (Zea mays L.) intercropped with palisadegrass (Brachiaria brizantha cv. Marandu) is considered a highly relevant cropping system to deliver both residue and forage. However, the benefits of inclusion of palisadegrass in maize systems and its influence on fertilizer dynamics and nitrogen (N) budget as well as the period after maize harvest for which palisadegrass continues to grow remain unclear. Thus, we conducted field studies to determine crop growth, end-season biomass, N fertilizer recovery, and overall N budget between an intercrop and a monoculture at two different sites during conventional and late-planted maize seasons. The cropping systems evaluated were maize and palisadegrass in monocultures and two intercrop patterns, serving as cover crop or forage with simulated grazing. From planting to grain harvest, intercrop patterns did not affect grain yield, final N content, and N fertilizer dynamics. Post-harvest, palisadegrass from intercrop patterns improved biomass from 1 to 10 Mg ha?1 and N content from 8 to 300 kg ha?1, relative to fallow after maize monoculture. Contribution of palisadegrass intercropping on N fertilizer recovery was low at approximately 4.5 kg ha-1 when both the crops were growing simultaneously and approximately 2.4 kg ha?1 following maize grain harvest. In three out of four sites over 2 years, intercrop patterns did not affect total N fertilizer recovery compared with their monocultures, averaging at approximately 51 %. Advantages of maize-palisadegrass intercropping on biomass, yield, and N cycling were documented at the site where maize was planted during the conventional season, despite the yearly variation in weather conditions. A negative N budget of ?230 kg ha?1 was estimated when grazing was simulated during the conventional maize planting season, suggesting greater N requirements of the intercropped palisadegrass when serving as forage.
