FORAGE PRODUCTION AND QUALITY OF RED RICE
Abstract
Utilization of red rice as forage plants constitute a control method of this weed along with a gain in animal products. An experiment was carried out at Estação Experimental de Terras Baixas/EMBRAPA CLIMA TEMPERADO, Capão do Leão, RS ,I3razil, to evaluate under, hydromorphic soil conditions, forage production, crude protein and "ia sita" digestibility of dry matter of red rice (Oryza saúva L.). In a split plot complete randomized block design, with four replications. The following variables were compared: a) Five seed densities in the soil (50, 150, 250,350 and 450 seeds/m 2); b) Two cutting times (vegetative and flowering) and c) Two red rice biotypes (straw hull and black hull). Higher forage production was obtained with one cutting in the flowering stage. The density of seeds in the soil influenced maximum forage production. Higher crude protein and "ia sita" digestibility was obtained with cuttings in the vegetative stage.
