dc.descriptionMaize-brachiaria intercropping has become adopted as a sustainable agricultural practice, capable of improving soil quality, optimizing nitrogen (N) use, and increasing the productive resilience of cropping systems. The objective of this study was to evaluate the effect of different N sources on the agronomic performance of maize. The experiment was conducted at Embrapa Agropecuária Oeste (Dourados, MS, Brazil). The experimental design was a randomized block design with a 2 × 4 factorial scheme, with three replications. The treatments included two maize cropping systems (monoculture and intercropped with brachiaria) and four N sources applied as topdressing: urea (45% N), urea with urease inhibitor (45% N), ammonium nitrate (27% N), and a control (no N). Plant height, biomass, grain yield, 100-grain weight, and nutrient content in the straw, and grains were evaluated. Maize monoculture showed greater accumulation of N and S in the grains, while maize-brachiaria intercropping increased C input in the straw and intensified nutrient cycling. N sources did not alter total biomass, but urea and urea with inhibitors increased N and Cu in the straw, and all increased N in the grains. It was concluded that intercropping combined with proper N management favors more sustainable systems for potential soil conservation.
