일시 수확형 고추를 직파하였을 때, 이랑 형태와 파종 거리 및 파종 깊이에 따른 수량차이는 인정되지는 않았다. 그러나 파종 시기를 앞당겨 4월 8일에 120×20㎝로 파종하였을 때 수량이 10a당 266㎏로써 높은 경향을 보였으며, 이랑 형태에 따른 파종 깊이는 120㎝의 이랑에서 0.3㎝ 깊이로 파종하였을 때가 수량이 10a당 334.8㎏으로 가장 높은 경향을 보였는데 이는 입모율이 74%로 높아짐에 따른 것으로 보이며, 터널 재배를 했을 경우 수량이 10a당 288㎏로 노지 재배보다 높았고 입모율도 향상되었다. Direct seeding of hot pepper can save labor comparing with the method that use transplants. The objective of this study was to evaluate effects of seeding space, depth, date, and low tunnel cultivation on yields of once-over harvested hot pepper (‘Jalapeno’ × ‘Indo’ and ‘9837059’). Hot peppers were direct-seeded in single or double rows at various seeding depths on several planting dates. Seeds also were sown inside and outside plastic tunnels. There were no significant effects of seeding space, depth and date on plant stand or yield, although early seeding and shallow seeding depths tended to increase both these variables. The best treatment combinations for plant stand and yield was using a double row 60 ㎝ apart (on a 120 ㎝ wide bed) with 20 ㎝ in-row spacing and 0.3 ㎝ planting depth. Low tunnel cultivation also increased stand rate and yield of hot pepper.

착과방법이 방울 토마토 생육, 수량 및 과실 품질에 미치는 영향을 구명하고자, 품종은 ‘꼬꼬’와 ‘산체리/스페셜’을 이용하였고, 착과방법은 벌 수정, 진동수분, 토마토톤 처리를 하였다. 두 품종 모두 착과처리 방법 간에는 생육 및 수량차이가 없었다. 종자수, 과육률 및 과즙률 함량은 유의한 차이가 있었으나 과피의 경도나 압축강도 등은 차이가 없었다. 당도, 산도, L*a*b* 표색계 값 등도 차이가 없었고, 수확 7일 후의 과실의 감모율이나 비상품과 발생률도 차이가 없었다. 과피의 조직을 검경한 결과 과피두께나 과피하부 조직에 차이가 없었다. 따라서 방울토마토 착과방법은 수정벌이용이 다른 방법에 비하여 생육이나 품질에서 큰 차이가 없어 적합할 것으로 판단된다. This study was conducted to investigate the effects of fruiting methods on growth, yield and quality of ‘Koko’ and ‘Suncherry’ (grafted ‘Special’ stock) tomato (Lycopersicon esculentum var. cerasiforme Alef.) .Methods of fruiting were bee (Bombus terrestris), vibration, and 4-CPA treatment. There were not significant differences among fruiting methods in growth and yield of ‘Koko’ and ‘Suncherry/Special’ tomato. Number of seeds, flesh and juice ratio of fruit were different significantly, whereas, hardness and compressive strength of pericarp were not different significantly among fruiting methods. There were not significant differences among fruiting methods on soluble solids, acidity content, ratio of fruit reduction, and occurrence ratio of unmarketable fruit of investigated tomatoes on the 7th day after harvest. It is not easy to distinguish the difference of pericarp color with naked eye among the fruiting methods or between varieties because, L* value is low and a*, b* value is closed together at the same position of L*a*b* color chart. So, it is not supported that storage quality was decreased and pericarp color was changed dark-red in bee pollination treatment. There were not significant differences in thickness and state of pericarp observed by microscope among fruiting methods or between varieties. Therefore, it was considered that the bee fruiting method is good because fruit quality was not different significantly among fruiting methods or between varieties.
