Nitrogênio na produção e diagnose foliar do capim-mombaça

Boletim de Indústria Animal, 2013
O nitrogênio é um nutriente de elevado impacto na produtividade das gramíneas forrageiras tropicais. Entretanto, há carência de informações quanto à diagnose foliar para nitrog ênio para uma série de capins. Avaliou-se o efeito do nitrogênio na produção de massa seca, na concentração desse nutriente no tecido vegetal, no valor SPAD nas lâminas foliares,
