This experiment was carried out to investigate the effect of liquid-pig-manure application method (Tr.1: surface appl. LPM 150%, Tr.2: surface appl. LPM 50% + LPM 50%, Tr.3: chemical fertilizer, Tr.4: soil injection LPM 150%, Tr.5: soil injection LPM 50% + surface appl. 50%, Tr.6: no fertilizer) and the economic efficiency of yield on forage crops cultivaion. In barley cultivation experiment, Tr.5 was found to be best, showing the yield of 1,462 kg , and followed by Tr.2(1,226 kg ), Tr.3(1,226 kg ), Tr.4(1,225 kg ) and Tr.1(1,209 kg ) in order. In maize cultivation experiment, Tr.4 was found to be best, showing the yield of 2,142 kg/10a, and followed by Tr.1(2,125 kg ), Tr.3(2,024 kg ), Tr.5(2,011 kg ) and Tr.2(1,925 kg 1) in order. The income was showing 1,274,000 ~ 1,591,000 Won in barley, whereas 766,000-794,000 Won 1 in maize. There was more economical efficiency in barley cultivation than maize cultivation. Rather than the LPM surface application, LPM soil injection was more effective.
