    This study was conducted to investigate rice yield and soil chemical properties affected by incorporation levels of green barley (GB) and hairy vetch (HV). The GB and HV were applied to the pots at 500, 1,000, 1,500, and 2,000 kg 10<SUP>-1</SUP> (GB500, GB1000, GB1500, GB2000, HV500, HV1000, HV1500, and HV2000, respectively), and inorganic fertilizer (N-P-K = 9-4.5-5.7 kg 10a<SUP>-1</SUP>) treatment as control. After rice harvesting, chemical properties of soil such as pH, OM, T-N, and available P<SUB>2</SUB>O<SUB>5</SUB> in GB and HV treated treatments were improved over those in Control treatment. The rice yield ranged from 433 to 512 kg 10a<SUP>-</SUP>1 for GB treatments and 490 to 532 kg 10a<SUP>-1</SUP> for HV treatments, indicating that rice yield was affected by incorporation levels of GB and HV. The rice yields in GB2000, HV1000, HV1500 and HV2000 treatments increased by 3.3, 3.1, 6.4 and 7.4% compared with Control treatment, respectively. Therefore, minimum incorporation level of GB and HV for increasing rice yield was 2,000 kg 10a<SUP>-1</SUP> of GB and 1,000 kg 10a<SUP>-1</SUP> of HV.
