S.  aBiomass production and mineral nutrient accumulation by weeds and sweet orange trees in the Amazonian.h[electronic resource]  c2019  aAccumulation of biomass and competition for nutrients can be used as parameters to identify species with higher potential for competition and, thus, with larger interference in crops. Consequently, studies addressing these parameters are important to weed science since they are the main factors that negatively affect the growth and productivity of cultivated plants. The objective of this research was to identify the species of weed plants with the largest potential of biomass production and accumulation of mineral nutrients in their leaves, which in turn, lead to higher interference in orange crops.  aCitrus Sinensis  aFruta Cítrica  aMineral nutrition  aWeed community1 aCARVALHO, J.
