초록

Yield gap of sesame between leading (110kg/10a) and usual farm (66kg/10a) is 60%. Purpose of this research is to investigate the reason and compensate the defects, thus reduce the yield gap between these two groups.

Firstly, questionnaire on cultivation practice and final yield was conducted to figure out which is the main reason of yield decrease. For each cultivation practices such as planting density and pest control, ratio of farmers who follow the standard cultivation method and who are not was calculated. According to this survey, following the appropriate planting density (31.6%), and renewal of varieties (26.9%) turned out to be the most influential factors affecting yield.

Based on the aforementioned results, plant growth and yield in customary and standard cultivation farm were compared. This investigation was conducted in five regions-Goesan, Yecheon, Miryang, Gochang and Haenam. 1000-seed weight and yield showed significant difference between varieties and planting density. Farmers who followed the standard cultivation method achieved higher yield and seed quality. Therefore, providing appropriate guidance to customary cultivation farmer using these results is strongly required.... 중략
