Signal Grass Deferred Pastures Fertilized with Nitrogen or Intercropped with Calopo

This study aimed to evaluate the accumulation, structural characteristics, and chemical composition of deferred signal-grass pastures that were subjected four treatments: without nitrogen fertilization, intercropped with calopo (Calopogonium mucunoides), fertilized urea N (50 kg ha−1 100 ha−1) for 2 years. The design was in randomized blocks, two blocks repetitions each treatment per block. There effects interaction between year on green dry mass, forage density vegetative tillers, crude protein content (simulated grazing). treatments height, falling index, mass/dead mass ratio, number dead, live total (direct cutting) also observed. Signal-grass–calopo-intercropping ensured adequate accumulation equivalent those pastures. In addition, pasture showed a higher percentage leaves compared other ratio highest only low dose nitrogen. Therefore, signal-grass–calopo-intercropping may be recommended deferment.
