The aim of this study was to evaluate the Paspalum oteroi native grass and its adaptive responses shading foliar fertilization in two pasture systems Cerrado-Pantanal transition region. A completely randomized block design with factorial arrangement adopted study: three types fertilizers [no – control (C); Foliar fertilizer for (FF) Soil + (SF)] x (WS - shading, wooded P. pasture; NS no exclusive pasture) four repetitions. seedlings were transplanted November 2015. Data collection from May 2016 September 2016, during dry season. There differences (p<0.05) sward height variables (H), matter (DM), crude protein (CP) content, production (DMP) shoot: root ratio (S:R). In WS system increased 8,61% CP content SF 8.81% content. However, observed reduced DM, DMP S:R FF leaf area index (LAI), latter months application. Probably, developed adaptation strategies deal environmental conditions which it submitted study, such as variations morphophysiological traits: low shoot / ratio, height, chemical composition, e light interception. conclusion, showed systems, period, however, use depends on economic viability studies.
