When rice straw was mulched, the inhibition of weed growth was observed in the barley field. This study was carried to indentify the influence of rice straw extract on germination, shoot and root growth of barley and water foxtail, according to extraction rate, temperature, growth stage, variety and soaking time. The inhibition rate of geramination, shoot and root length of barley and water foxail was higest in rice straw extract of 24 degrees, 5hours, 10%(w/v). Daerimbyeo's extract among 17 rice varieties inhibited growth of barley most, but Anjoongbyeo's was lowest. Among five growth stages, extract at seedling stages inhibited growth of barly and water foxtail most. Among 10 barley varieties, Seaolbori showed the greatest growth inhibition by rice straw extract.
