BRS AG: first cultivar of irrigated rice used for alcohol production or animal feed

BRS AG is an irrigated rice cultivar developed by Embrapa, recommended for cultivation in the state of Rio Grande do Sul. It is intended for grain alcohol production or animal feed, with average thousand-grain weight of 52g (double of the conventional cultivars) and average yield of 8193 kg ha^-1.

Key words:
Oryza sativa L.; large grain; crop diversification.
