Abstract
A structured questionnaire was used to collect data with 184 observations of the cooperative
farmer group and 230 that of the non-cooperative farmer group. The results indicated that technical
efficiency mean of the cooperative grower group was greater than that of the non-cooperative grower
group in seasons 2, and 3, while this figure of the cooperative farmer category was lower than that of the
non-cooperative farmer category in the first season. Additionally, the positive determinants of technical
efficiency in the cooperative farmer group were the age and plant density in season 1, the wrapping bag
in seasons 1, and 2, the land area in season 1, and 3, and the credit access and market access in season 3.
Meanwhile, the negative factors were the payment for agro-input wholesaler and classifying sale in
season 1, the credit access in season 2, the age, education, farming experience and plant density in season
3. In the non-cooperative farmer group, the positive determinants were the land area in seasons 2, and 3,
the credit access in season 2, and the plant density in season 3. However, the negative elements were the
wrapping bag in seasons 1, and 2, the age, education, farming experience, market access and land area in
season 1, and the classifying sale in season 2.
