This study was conducted to investigate the effects of using barley seeder attached to rice harvest combine that could be used in rice harvesting and barley seeding simultaneously on the growth characteristics of barley and labor-saving efficiency. In developed seeding system, burley seeding was earlier about 5 days than in the conventional system, because of conducting rice Harvesting and barley seeding simultaneously. The germination of barley seed after seeding was protected from drought damage by the rice straw covering. Among the growth characteristics of barley using developed seeding system, the number of spikes per m$^2$ was lower than that of conventional system, but others showed longer culm length, hove kernel numbers per spike and heavier 1,000 kernel weight than those of conventional system. Developed seeding system resulted in about 57% labor-saving efficiency compared with conventional system. The cost of whole works from seeding to harvest of barley was saved about 8% compared with conventional system. A total of income increased about 16% than that of conventional system.
