T. da; FONSECA, D. M. da; VAN CLEEF, F. de O. S.; CARVALHO, B. H. R.; ROCHA, G. de O. Repository: BDPA Publication year: 2022
Plant morphology and herbage accumulation of signal grass with or without fertilization, under different light regimes. Author(s): LOPES, C. M.; PACIULLO, D. S. C.; ARAÚJO, S. A. do C.; MORENZ, M. J. F.; GOMIDE, C. A. de M.; MAURÍCIO, R. M.; BRAZ, T. G. dos S. ABSTRACT - The silvopastoral system has been suggested as an alternative to recover degraded pastures in tropical regions.
