Spartina spartinae is the dominant species of halo-hydromorphic plains with low floristic diversity in south-east of the Santiago del Estero province. The aim of this work was to analyze production and quality of S. spartinae rangelands after the application of four disturbance sequences: burning (F), mechanical cutting (C), herbicide application (H), and undisturbed (T), applied successively on September 2012, and March 2013. All disturbance sequences showed favorable results compared to T and generated higher levels of crude protein, biomass digestibility, increased available forage and reduced S. spartinae plant height, C-C showed higher productivity of available forage.
