초록

기장과 조의 생산량과 자급률 향상을 위하여 기장과 조의 기계화에 적합한 파종방법을 알아보기 위해서 지금까지 개발된 기장과 조의 기계화 파종방법에 따른 생육특성 및 수량특성을 알아보았다. 시험처리는 인력점파, 높은이랑 기계점파, 기계산파, 넓은이랑 줄뿌림 파종방법으로 실시하였다. 노동투입시간에서의 기장의 산파는 인력점파 대비 $16.07hr10a^{-1}$ 절감되었고, 조에서도 인력점파 대비 산파에서 $14.23hr10a^{-1}$ 절감되었다. 간장은 기장에서 2 및 3년차에서 산파 처리구에서 가장 큰 138, 125 cm가 조사되었으며, 조에서는 3년 모두 줄뿌림과 산파 처리구에서 가장 큰 것으로 나타났다. 간경에서는 기장과 조에서 3년 모두 가장 굵은 것으로 나타났다. 종실수는 인력점파 처리구에서 많은 것으로 조사되었다. 수량에서는 기장의 경우 대조구인 인력점파 대비 산파에서 15~32% 증수되었다. 조의 경우에서도 대조구인 인력점파 비해 산파에서 9.1~28% 증수되었다. 따라서 기장과 조의 기계화 파종시 산파하여 재배할 경우 노동효율 및 수량증대에 유리할 것으로 생각된다.

Cultivation techniques of proso millet (Panicum miliaceum L.) and foxtail millet (Setaria italica L.), such as sowing, weeding, and harvesting, are often not properly utilized, resulting in low productivity rates. The goal of this study was to develop cultivation techniques to increase millet productivity rates and reduce labor inputs. We evaluated the effects of different machine sowing methods compared with manual sowing methods from 2014 to 2016. The three machine sowing methods were dibbling, drilling, and broadcasting. Compared with manual sowing, the broadcasting method decreased labor times by 16.07 and $14.23hr10a^{-1}$ for proso and foxtail millets, respectively. Proso millet showed greater culm lengths at 138 and 125 cm with the broadcasting method for two years, whereas foxtail millet after three years had greater culm lengths from both the drilling and broadcasting methods. Both crops exhibited the thickest culm stems in the $3^{rd}$ year. The greatest number of seeds of the panicle were from the manual sowing method in both crops. Compared with manual sowing, broadcasting increased grain yields by 15-35% and 9.1-28% for proso and foxtail millets, respectively. Therefore, we suggest that the application of broadcasting in mechanical sowing will increase labor efficiency and yields of proso and foxtail millets.
