Abstract: The suitable harvest period, nutritive components and nutrient yields of 12 cultivars/combinations of indica rice as green feed were studied in 1994-1995. The result showed that the average outputs of dry matter, crude protein, fat and carbohydrate of the vegetative mass of rice (green feed) were 150. 4%, 243. 1 %, 207. 7% and 104. 9 % as comparing with those of rice grain. The days to harvesting were 20-28 d shorter in green feed than that of rice grain. In those tested c u it ivars /combinat ions, Xie yo u 2 8 8, Shanyou 48-2 and Xieyou 210 would be good as green feed, and the suitable harvest period is in late booting to heading stage.
