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