This experiment was conducted to investigate an optimum seeding date of soybean for soy sauce and tofu in Kyungnam region for 2009~2011. Soybean seeds of Seonyu(quasi-early maturity) and Daewon(mid-late maturity) were sown from May 10 to June 25 at the 15-day interval, and dry matter production, disease occurrence, lodging and soybean yield were evaluated. Days to vegetative and reproductive growth in two varieties became longer as seeding date was early. Dry matter weight per unit area in R5 stage of Seonyu was the heaviest at the June 10 seeding and all seeding dates produced optimum range of leaf area index. Dry weight of Daewon in R5 stage was heavier as seeding date was earlier while leaf area index reached to optimum except the June 25 seeding. The ratio of sink/source in Seonyu and Daewon was lowest at the May 25 seeding date, which meaned the lowest load of leaf to pod. Yield of Seonyu was not significantly different among the seeding dates. Yield of Daewon was also significantly high at the May 25 seeding as compared with other seeding dates. The low yield of Daewon at the June 10 seeding was due to severe occurrence of diseases and black root rot in 2009 and bacterial pustule for 2009~2011. This result indicates that optimum seeding date of soybean for soy sauce and tofu was shown to be late May~early June in Kyungnam region.

콩의 비닐피복 재배시에 최적적심 방법을 구명하고자 본 시험에서 적심방법별 주요 특성 및 수량 비교한 결과는 다음과 같다. 1. R5 stage의 건물중은 두 품종 모두에서 V8 stage의 순적심과 개화시 적심에서 많았는데 이들 처리는 대원콩에서는 무처리 보다 가벼웠고 신부석태에서는 무처리 보다 무거웠다. 그리고 이들 처리는 최적엽면적 지수을 확보하였다. 2. 포장도복은 V8 stage의 순적심에서는 발생하지 않았고 개화시 적심에서는 2~5 정도의 도복이 발생하였다. 3. 개화기는 품종별 처리간 모두 같았고, 성숙기는 대원콩에서 1~2일의 차이를 보였지만 신부석태는 차이가 없었다 4. 종실비대기간인 R5 stage에서 R7 stage까지의 두 품종 평균 순동화량(NAR)은 V8 stage의 순적심과 개화시 적심에서 비슷하면서 가장 높았다. 5. 두 품종 평균수량은 V8 stage의 순적심과 개화시 적심에서 가장 높았다. 6. 외관적 품질에서는 V8 stage의 순적심에서 백립중이 가장 무거웠고 미숙립 및 다른 피해립율도 낮았다. This experiment was carried out to make clear optimum decapitation method for yield increase of soybean and to reduce lodging as soybean is cultivated in vinyl mulching. Results are as follow; In R5 stage, dry matter weight in two varieties was higher in V8 (terminal) treatment and flowering initiation stage treatment which were lighter than control in Daewon and heavier in Sinbuseoktae. Also, LAI(Leaf Area Index) in these two treatments was suitable. Lodging index in V8 (terminal) treatment was not occurred whereas in flowering initiation stage treatment was ranged from 2 to 5. Flowering date in two varieties was not differant among five treatments and maturity date was similar. NAR (Net Assimilation Rate) from R5 to R7 stage was higher in both V8 (terminal) and flowering initiation stage treatment showing similar mean value. Although mean values was not significantly different, the yield of terminal decapitation in V8 stage which was similar to flowering initiation stage treatment was higher. Also, 100-seed weight of terminal decapitation in V8 stage was the heaviest and apparent seed quality was favorable. Consequently, the optimum decapitation method in vinyl mulching cultivation of soybean was terminal decapitation in V8 stage.

남부지역 친환경 논 재배에 적합한 나물콩 품종을 선발하고자 풍산나물콩 등 29 품종을 공시하여 밭 재배와 비교하여 생육특성, 습해정도 및 수량성을 비교 검토하였다. 1. 논 재배시 개체당 협수 및 개체당 립수는 밭 재배에 비해 큰 차이로 적었으며, 경태는 대체로 얇았고 성숙기는 공시 품종 대부분에서 밭 재배에 비해 5~14일 정도 지연 되었다. 2. 무 농약(살충제) 재배시 영양생장기에는 땅거미 등의 천적으로 인하여 콩의 생장에 큰 문제는 발생하지 않았으나, 노린재류의 피해는 입비대기에 심했는데, 품종 간 피해 정도가 달라 친환경 논 재배에 적합한 내충성 나물콩 품종 선발이 가능하였다. 노린재 저항성을 보인 품종으로는 소원콩, 풍원콩, 소록콩, 풍산나물콩, 소백나물콩, 광안콩, 푸른콩, 부광콩, 팔도콩 및 녹채콩이었다. 3. 개화기 이후 한 달 이상 지속된 강우와 무 농약(살균제) 재배로 인하여 협의 탄저병 및 종실의 자반병, 미이라병의 감염정도가 품종간 크게 나타나, 친환경 논 재배에 적합한 내병성 나물콩 품종 선발이 가능하였다. 포장에서 병 발생이 적은 품종으로는 팔도콩, 광안콩, 도레미콩, 소명콩, 풍산나물콩, 익산나물콩, 서남콩, 소진콩, 푸른콩, 보석콩, 남해콩 및 소록콩이었다. 4. 공시품종들의 백립중은 9.8~17.2g 범위에 속하였으며 대부분의 품종에서 밭 재배 대비 0.1~3.7g 증가하는 경향이었으나, 일부 품종에서는 오히려 약간 감소하였다. 정부수매 규격상 소립나물콩(선별체 직경 4.0~5.6mm)에 해당되는 품종은 다원콩(9.8g), 다채콩(9.9g), 보석콩(10.3), 서남콩(10.4g), 소강콩(10.7g), 한남콩(11.0g), 소명콩(11.1g) 및 원황콩(11.3g)이었다. 5. 풍산나물콩(266kg/10a)에 비해 수량이 높았던 품종은 소록콩(308kg), 한남콩(288kg), 보석콩(281g), 소원콩(271g)이었으며, 흑색 종피를 가진 다원콩은 146kg에 불과한 낮은 수량성을 나타냈다. 6. 수확된 종자의 발아특성을 살펴보면 평균발아기간은 2일 이내였으며, 대부분의 품종에서 발아세는 77~99%, 최종 발아율은 89~100%로 높은 발아율을 나타냈으나, 다원콩 및 장기콩에서는 경실종자 및 부패립으로 인하여 발아세 및 발아율이 70% 이하로 매우 낮았다. 7. 공시된 나물콩 품종들의 내병성, 내충성, 내도복, 립중, 수량성, 내습성 정도 및 콩나물 특성을 종합적으로 고려해서 판단해 보면 서남콩, 한남콩, 도레미콩, 보석콩, 풍원콩, 광안콩, 소원콩, 다기콩, 팔도콩, 은하콩, 및 풍산나물콩이 높은 수량과 립 크기의 균일한 분포를 나타내어 친환경 논 재배에 유망시 되었다. We carried out the experiment to select the suitable sprout soybean varieties for environment-friendly cultivation in paddy field of southern part area, compares of excess moisture injury degree and yield ability among 29 sprout soybean varieties. Plant growth of sprout soybean was generally low in beginning and recovered after flowering due to rainfall. In paddy field cultivation, number of pod per individual and number of seed per individual were less in difference than upland cultivation, and maturing date was delayed 5-14 days than upland cultivation in most species. When environment-friendly cultivation, pest injury was not caused major problem for the growth during the vegetative period of soybean due to ground spider as natural enemy to insect pest. However, damage of stink bugs showed severe during grain filling period, and Dawonkong, Anpyeongkong, Dachaekong and Wonhwangkong showed susceptible to sting bug. SMV infection was weak and showed some necrosis symptoms in Sokangkong, but black root rot was not infected at all. Bacterial pustule began to be infected slowly from pod enlargement stage in most species, displayed severe symptoms in Dawonkong, Pungsannamulkong, Seonamkong and Sobaeknamulkong. The symptoms of pod anthracnose, pod blight and purple spot were greatly appeared after flowering. Disease resistance varieties was Paldokong, Kwangankong, Doremikong, Somyeongkong, Pungsannamulkong, Iksa-namulkong, Seonamkong, Sojinkong, Pureunkong, Bosugkong, Namhaekong and Sorokkong. Lodging index showed 3 in Saebyeolkong, and other species displayed slight lodging in 0-3 degree. 100-seed weight is 9.8-17.2g extent and increased 0.1-3.7g than upland cultivation in most species, but decreased in some species. Government purchase standard, species correspond to small-seed-size namulkong (Sizing screen diameter 4.0-5.6 mm) was Dawonkong, Dachaekong, Bosugkong, Seonamkong, Sokangkong, Hannamkong, Somyeongkong and Wonhwangkong. Species which seed yield was higher than Pungsannamulkong (266kg/10a) were Sorokkong, Hannamkong, Bosugkong and Sowonkong. Considering sprout soybean species, disease endurance, insect resistance, lodging resistance, 100-seed weight, yield ability and excess moisture tolerances synthetically, Seonamkong, Hannamkong, Doremikong, Bosugkong, Pungwonkong, Kwangankong, Sowonkong, Dagikong, Paldokong, Eunhakong and Pungsannamulkong were promising for environment-friendly cultivation in paddy field.
