본 연구는 수동식 감자 파종기구를 활용한 인력파종 및 트랙터 부착형 파종기를 활용한 기계파종을 비교하여 강원도 고랭지 지역의 여름감자 파종작업에 대한 작업효율 및 경제성을 분석하였다. 작업효율은 일정 면적을 파종하는 데 소요되는 시간으로 도출하였다. 동일한 작업효율을 가지는 조건에서 인력파종 및 기계파종의 연간 고정비와 연간 유동비를 산출하여 각 파종작업에 대한 경제성 분석을 수행하였다. 이때 고정비로는 감가상각비, 이자 및 수리비를, 유동비로는 인건비와 유류비를 고려하였다. 또한, 총비용 소요 분석을 통해 트랙터 부착형 파종기가 수동식 감자 파종기구 대비 경제성이 높아지는 시점을 도출하였다. 분석 결과, 기계파종이 인력파종 대비 약 4.6배 높은 작업효율을 보였으며 파종률은 두 방식에서 모두 100%로 나타났다. 경제성의 경우 구매 비용은 트랙터 부착형 파종기가 높았으나, 인건비 측면에서 비용 절감 효과를 보였다. 이에 따라 4년 9개월 이후부터 트랙터 부착형 파종기의 총 소요비용이 수동식 감자 파종기구의 총 소요비용 대비 낮아지는 것으로 나타났다. 따라서 장기적인 관점에서 기계파종이 인력파종 대비 생력화 효과가 크며 경제성도 높은 것으로 판단된다.
Abstract
This study examines the work efficiency and economic analysis of manual seeding using a hand-operated potato seeder and mechanical seeding using a tractor-mounted seeding machine for summer potatoes in the highland areas of Gangwon-do. Work efficiency was calculated based on the time required to seed a given area. Under conditions of equal work efficiency, the annual fixed costs and variable costs for both manual and mechanical seeding were calculated to perform an economic analysis of each method. Fixed costs included depreciation, interest, and repair costs, while variable costs considered labor and fuel expenses. Additionally, a total cost of ownership analysis was conducted to determine the point at which the tractor-mounted seeding machine becomes more economical than the hand-operated potato seeder. The analysis revealed that mechanical seeding demonstrated approximately 4.6 times higher work efficiency than manual seeding, with both methods achieving a 100% seeding rate. Although the initial purchase cost of the tractor-mounted seeding machine was higher, it offered significant labor cost savings. As a result, after 4 years and 9 months, the total cost of using the tractor-mounted seeding machine was lower than that of the hand-operated potato seeder. Thus, from a long-term perspective, mechanical seeding is considered to be more labor-saving and economically advantageous compared to manual seeding.
