Despite tropical grasses being the main feed source for major part of ruminant livestock, information about nutritional qual- ity changes under climate changes scenario are still scarce. The novelty of this work was to determine the effects of season and elevated C O 2 under field conditions upon biomass production and nutritional value of Brachiaria decumbens during 2 years. The Free-Air Carbon Dioxide Enrichment was established in twelve rings: six of them being the control (current atmosphere) and others six fumigated with pure CO 2 to achieve a higher concentration (e[CO 2 ]). In each ring, two 0.25 m 2 plots have been established with B. decumbens and after standardization cut, green forage yield was evaluated frequently. Plant samples were collected at 20 cm height and evaluated for determining the biomass production, nutritive value and in vitro enteric methane (CH 4 ) production. Season and year had significant effect (P < 0.01) upon all the studied variables. Biomass production, acid detergent fibre and cellulose contents of samples from e[CO 2 ] were statistically greater (P < 0.05). Carbon, nitrogen and crude protein content were within the normal range and as well as C H 4 production were not altered by e[CO 2 ] (P > 0.05). Overall, e[CO 2 ] and rainfall seasons significantly increased forage production, contributing to sequester carbon in plant biomass, but this C 4 tropical grass must be grazed at its best protein and fermentable carbohydrate ratio for advantages in the rumen microbial synthesis and lowering CH 4 production intensity of the production system.
