Knowledge about the decomposition of litter in signal grass pastures is still limited, especially managed under deferred grazing. Thus, we aimed to evaluate chemical composition, carbon/nitrogen (C/N) ratio, and rate (Urochloa decumbens cv. Basilisk) not fertilized with N (U0), 50 kg·N·ha−1 (U50), 100 (U100), intercropped calopo (Calopogonium mucunoides Desv.) (UC), grazing at different incubation times for two experimental periods (2017–2018 2018–2019). Data were analyzed using a randomized block design four management systems blocks, each containing replicates per treatment. Nitrogen sources increased concentrations before incubation. incubated affected by periods, increasing over time, mainly U50 U100. U100 samples exhibited higher acid detergent insoluble nitrogen (ADIN) levels than U0 only period 2. Notably, C/N ratio did differ systems; however, it decreased final values 24:1 26:1 1 2, respectively. Overall, from or biological concentrations, but their ADIN concentrations. However, affect ratios no differences biomass observed among systems, possibly due occurring prior sampling.
