Conteúdo: | A glasshouse experiment was conduced examine mineral acquisition and utilization strategies of Brachiaria decumbens (BD), Brachiaria brizantha (BB) and Panicum maximum (PM). The plants were grown under nime treatments resulted from the combination of there levels of nitrogen (25, 150 and 300kg/Nha). BD showed the lowst value of root weight and root length per pot, the  highest efficiency of P and N Nuptake (P and N uptake mg/ unit root weight g). On the other hand, PM showed lower mineral uptake efficiency, but the higlest mineral use efficiency (dry matter production g / absorbed P and N mg). Moreover, total P and  N uptake in BB was the higlest, and  this seens to be achieved by the multiplicative  effect of moderate mineral uptake efficiency and the moderate size of the root system.
