This study was carried out to evaluate the economic value of Tyvek planting technique in Korean citrus. The Tyvek planting technique was developed by national institute of horticultural and herbal science in Korea rural development administration. This technology could be used to improve efficiency and practicality of cultivation of citrus. The research results show that the technological value of Tyvek planting technique was evaluated 42,163(discount rate 6%)-55,018(discount rate 8%) million won. IRR is greater than discount rate(6-10%). NPV is greater than zero. B/C ratio IRR is greater than 20. The economic validity of Tyvek planting technique is identified by the results of technology evaluation. Key Words : Tyvek planting technique, Citrus, NPV, IRR, Technology Evaluation. * Corresponding Author : Bae-Sung Kim(JeJu National Univ.)Tel: +82-64-753-3353 email: bbskim@jejunu.ac.krReceived April 15, 2013 Revised June 20, 2013 Accepted July 11, 2013 1.                .
