This study was conducted to investigate the effects of application of composted cattle manure (CCM) on the productivity of the whole crop rice (WCR) and Italian ryegrass (IRG) on both Sancheong and Asan area from 2005 to 2008. Application levels of CCM such as chemical fertilizer (CF), CCM 150% and CCM 200% were tested in paddy field. Amount of CCM was adjusted equal to total nitrogen value relative to its value of CF. Mean dry matter yield (DMY) of WCR and IRG increased in order; CCM 200% > CF > CCM 150% in Asan and there was no significant difference between CCM 200% and CF. In Sancheong, DMYs of WCR and IRG significantly decreased (p<0.05) in order CF > CCM 200% > CCM 150%. The plant length and number of tiller of WCR were not different among treatments, however the percentage of ripeness of WCR was higher (p<0.05) in CF compared to CCM 150% and CCM 200%. Also, there were no differences in NDF and ADF contents, however CP content was higher (p<0.05) in CF treatment compared to CCM 150% and CCM 200%. Based on the results of this experiment, IRG-WCR double cropping system with application of CCM may be effective in producing the forage resources of 18~20 tons every year with eco-friendly way.
