Abstract

This study has used introduced and local varieties and involved several low and medium-sized regionswith 250 small farmers in the driest region of Eastern Indonesia. This study aimed to determine differenceson the level and distribution of productivity, profitability, technical efficiency and sources of inefficiencybetween agro-ecological zones and introduced mungbean varieties and local varieties. Data were analyzedfrom descriptive, economical, and technical efficiency perspectives with technical inefficiency effect model onthe Cobb-Douglas production function as well as estimated using Frontier 4.1. The results showed thatlowland with introduced production of vima-1 resulted higher productivity and profitability compared tomedium land. However, local varieties were considered more technically efficient than introduced varieties.This is due to significant differences between the production systems in each zone and the varieties cultivatedby farmers. Technical production factors that have a significant effect on productivity and profitability ofgreen beans are quality seeds, fertilizers, and labor.Green bean farming in lowland areas with introducedvarieties of vima-1 shows a higher level of technical efficiency than medium land. However, green beanfarming both in the lowland and medium land, both introduced and local varieties, operates in conditionsthat technically are not efficient. Important factors that can reduce technical inefficiencies in green beanfarming are age, education, experience, farmer groups, counseling and mentoring for farmers. Efforts toincrease productivity, profitability, and technical efficiency that need to be implemented both in lowlandand medium land are promoting sustainable seedling system programs, improving input and productionprocess technology, and improving the technical efficiency of green bean agribusiness by improving technicalskills and managerial capabilities of producer farmers which specific to zones and varieties.
