Abstract

This study was conducted to establish proper milling condition and harvesting time for improving the milling recovery of head foxtail millet grain. Brown foxtail millet recovery and the percentage of head foxtail millet recovery were significantly different according to the number of hulling and milling time. Also, the interaction of these factors had influence on brown foxtail millet recovery and the percentage of head foxtail millet recovery. To improve the percentage of head foxtail millet recovery, it was effective to hull grain twice and mill for 1.30 minute. 1000-grain weight of brown foxtail millet, brown foxtail millet recovery, hardness of brown foxtail millet, milling recovery, and the percentage of milling recovery of head foxtail millet grain were significantly different according to harvesting day after heading. For improving the ratio of ripened grain and the percentage of recovery of head foxtail millet, it is recommended to harvest 45 days (accumulated temperature : $1,148^{\circ}C$) after heading (DAH) in early maturing Hwangkeumjo, 50 DAH (accumulated temperature : $1,150^{\circ}C$) in mid-late maturing Samdamae and Kyeongkwan1, and 55 DAH (accumulated temperature : $1,168^{\circ}C$) in late maturing Samdachal.

본 연구는 국내에서 재배되고 있는 조 품종의 도정수율 증진을 위한 도정방법 및 적정 수확시기를 검토한 결과를 요약하면 다음과 같다. 제현횟수와 도정시간에 따라 제현율과 완전미도정수율의 차이가 인정되었고, 이들의 상호작용에 있어서도 유의성이 인정되었다. 조의 완전미도정수율은 제현횟수를 2회, 도정시간을 1분 30초로 하였을 때 높았다. 출수 후 수확일수에 따른 현곡천립중, 제현율, 현곡의 경도, 도정율과 완전미도정수율의 차이가 인정되었고, 이들 요인간 상호작용에 있어서도 유의적인 상관이 인정되었다. 등숙율과 완전미도정수율 향상을 위해 조생종인 황금조는 출수 후 45일(적산온도 $1,148^{\circ}C$), 중생종인 삼다메와 경관1호는 출수 후 50일(적산온도 $1,150^{\circ}C$), 만생종인 삼다찰은 출수 후 55일(적산온도 $1,168^{\circ}C$)에 수확하는 것이 가장 적당하였다.
