Abstract

This experiment was conducted from 2002 to 2004 at paddy field of National Livestock Research Institute, RDA, Suwon to investigate the select the promising double cropping system on growth, yield and nutritive value of summer forage(silage corn, sorghum$\times$ sudangrass hybrid, japanese millet, jobs tear, rice) and winter forage(rye, barley, Italian ryegass) and also to determine the best double cropping system necessary to maximize the total forage yield of winter forages plus summer forage crops. Among agronomic characteristics, lodging tolerance appeared to be highest in the summer forage crop including silage corn, jobs tear and rice compared to other forage crops. And lodging tolerance appeared to be highest in the winter forage crop including barley compared to rye and Italian ryegrass. The highest dry matter yield of 27,766 kg/ha, 27,296 kg/ha and 25,365 kg/ha obtained from an whole crop barley+sorghum$\times$ sudangrass hybrid, rye+sorghum$\times$ sudangrass hybrid and Italian ryegrass+sorghum$\times$sudangrass hybrid double cropping sequence in combination among the fifteen cropping systems((P<0.05). And dry matter yield of barley+silage corn and rye+silage com were 23,766 and 23,572 kg/ha.
