본 연구는 주요 조생종 콩의 생육과 종실품질 및 수량을 비교하여 남부지방 다모작 재배농가의 조생종 콩 품종선택에 활용하고자 전남 나주(위도 35˚04'N, 경도 126˚54'E)에서 6월 15일에 파종하여 수행하였다. 큰올콩과 화성풋콩은 성숙기가 9월 12일로 빨라 작부체계 도입에 유리할 뿐만 아니라 종실품질과 수량이 양호하였다. 그리고 새올콩과 신록콩은 성숙기가 9월 20일 전.후로 조금 늦으나 종실품질이 좋고 수량이 많았다. 따라서 콩 후작물을 9월 중순에 파종하고자 할 때는 큰올콩과 화성풋콩이, 9월 하순에 파종하고자 할 때는 새올콩과 신록콩이 유리하였다. 그리고 주요 조생종 콩의 조기수확에 따른 종실품질과 수량성 등을 검토하여 조기수확 한계기를 구명하고자 수행하였다. 큰올콩은 수확적기(9월 12일)보다 6일전(9월 6일)에 수확할 때 입중, 수량, 종실품질 등이 적기수확과 차이가 없었다. 한편 새올콩은 수확적기(9월 24일)보다 6일전(9월 18일)에 수확할 때 입중, 수량, 종실품질 등이 적기수확과 차이가 없다. 따라서 큰올콩과 새올콩의 안정적인 조기수확 한계기는 수확적기 6일 전이다.
This study analyzed the growth, seed quality, and yield of major early-maturing soybean cultivars by comparing them in order to utilize the research results in the selection of early-maturing soybean cultivars in multi-cropping farms in the Southern area. This field trial was conducted at Naju region (latitude 35~circ04, longitude 126~circ54), Jeonnam, with planting on June 15. The maturing date for Keunol-kong and Hwaseong-put-kong was found to be around September 12, which was earlier than other cultivars. Thus, there were advantages to introducing a cropping system as well as having good seed quality and high yield. On the other hand, the maturing date for Saeol-kong and Sinrok-kong was found to be around September 20, which was a little bit late; however, the seed quality of the cultivars was good and they had a high yield. Therefore, if we want to sow the following crops of soybeans around mid-September, Keunol-kong and Hwaseong-put-kong are advantageous, while for the seeding around late September, Saeol-kong and Sinrok-kong would be good. This study was also performed to identify the limitation time for early harvesting by reviewing seed quality and yield of major early-maturing soybean cultivars according to early harvesting. When harvesting Keunol-kong on September 6, which was six days earlier than the optimal harvesting time (September 12), there was no difference in seed weight, yield, or seed quality than those of the harvested at the optimum maturing time. As for Saeol-kong, when harvesting on September 18, which was six days earlier than the optimal harvesting time (September 24), there was no difference in seed weight, yield, or seed quality than those of the harvested at the optimum maturing time. Therefore, the stable limitation time for early harvesting of Keunol-kong and Saeol-kong was concluded to be six days earlier than the optimal harvesting time.
