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.
