A study on cultivation models and mechanization rates for onion cultivation standardization: Focusing on the Gyeongsangnam-do

초록

Onion cultivation model in Republic of Korea vary greatly by region, making it difficult to stan- dardize farming machinery and hindering efficient mechanization. This study was conducted to establish a standardized onion cultivation model by surveying farmer located in the major onion-producing areas of Changnyeong, Hapcheon, and Hamyang in Gyeongsangnam-do. The survey also included factors such as intra-row spacing, inter-row spacing, ridge width, ridge height, furrow width, mulch width, and planting rows, with averages and modes analy- zed by region. The average age of farmers was 57, 55, and 52 ages in Changnyeong, Hapcheon, and Hamyang, respectively, and the cultivation area was 26,612, 50,103, and 36,992 m2, respectively. The results of the mode analysis for cultivation model showed intra-row spacing of 13 cm, inter-row spacing of 15 cm, furrow width of 40 cm, ridge height of 25 cm, ridge width of 110 cm, mulch width of 170 cm, and 8 planting row. The mechanization rate of onion cultivation was 100% for tractors, 53% for seeders, 67% for bed formers & mulchers, 58% for transplanters, 39% for stem cutters, 72% for harvesters, and 19% for collectors. In addition, some issues were raised that were problematic in improving machine utilization. The results of this study are expected to present useful results for the development of a standard mecha- nized cultivation model for onion cultivation.
