Agroforestry systems (AFS) are considered alternative land use options to help prevent soil degradation and improve microbial biomass organic C status. However, it is unclear how different densities of babassu palm [Attalea speciosa (syn. Orbignya phalerata)], which an important tree in Northeast Brazil, affect the biomass. We investigated activity under AFS with associated Brachiaria brizantha grass. Soil (MBC), N (MBN), MBC:total ratio, fluorescein diacetate hydrolysis dehydrogenase showed...

Foram avaliadas as características da biomassa do capim-tanzânia sob três frequências de desfolhação (85, 95 e 97% interceptação radiação fotossinteticamente ativa - IRFA) dois resíduos pós-pastejo (índices área foliar residual 1,0 1,8) em delineamento inteiramente casualizado arranjo fatorial 3 × 2, com quatro repetições. O maior período descanso foi verificado para o menor resíduo a frequência IRFA. Observou-se uma altura elevada, assim como IAF Já no caso densidade populacional perfilhos...

Gastrointestinal nematodes (GINs) cause considerable economic losses in grazing goat herds. At present, GIN control cannot rely on conventional anthelmintic (AH) drugs because parasites have developed resistance against such drugs. Thus, alternative methods are being sought to reduce the dependence AH. Many tannin-rich plants exhibit AH activity and may be used as alternatives for control. Mimosa caesalpiniifolia is a shrub consumed by small ruminants Brazil. This study evaluated vivo effect...

Variability in climatic conditions of low-latitude tropical grass cultivation can affect forage production dynamics. Pasture ecosystems are complex and preferably studied from a multifactorial point view through multivariate approaches. Therefore, this study, we characterized different growing for grasses the Megathyrsus genus studies conducted humid semi-arid conditions. We applied principal component, canonical correlation, discriminant function analyses to measurements agronomic...
