Abstract
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.
호남지역 보리 2모작 재배농가의 생력화를 위하여 벼 수확 동시 보리파종에 따른 보리의 생육특성 및 생력효과를 조사ㆍ분석한 결과를 요약하면 다음과 같다. 1 벼 수확동시 보리파종은 벼 수확과 동시에 이루어지므로 관행 파종방법보다 5일 이상 빠르게 파종되었다. 2. 벼 수확동시 보리파종재배는 한발시 볏짚피복에 따른 재해 경감효과가 있었으며, 보리수확기 볏짚 C/N율은 31.6％로 낮아졌다. 3. 벼 수확동시 보리파종시 생육특성은 관행재배보다 수수는 감소하였으나 간장, 1수립수 및 천립중 등이 증가하였으며, 수량은 관행 재배보다 평균 6.5％ 증수하는 경향이었다. 4. 벼 수확동시 보리파종 작업시간은 파종작업 단계축소로 관행파종방법보다 작업시간이 58％절감되었으며, 경영비는 8％ 절감되었고, 소득은 16％ 증가하였다.
