| Abstract | This research aims to evaluate losses in iceberg lettuce production across different seasons through a case study in Mae Chaem District, Chiang Mai Province. Data were collected from farmers’ planting plots under the supervision of the Mae Hae Royal Project Development Center. The data collection was divided into three seasons: summer, rainy, and winter. Each season, data were collected from 10 farmers, totaling 30 farmers. Data were analyzed using a completely randomized design (CRD). The results showed that the average weight per plant before and after trimming lettuce, the total yield weight before trimming per rai, and the total yield weight after trimming per rai were the highest in winter, followed by summer and the rainy season, respectively. Moreover, it was found that the winter season had the highest expected biological yield, which was not different from the summer season. In contrast, the rainy season had the least expected biological yield. However, the total weight of unharvested plants in the three seasons was not different. The parts that were trimmed off included the stems, roots, and leaves. There was no difference in the amount of trimming between summer and winter, with both seasons showing higher amounts of trimming compared to the rainy season. When classifying the causes of damage to the trimmed leaves, it was found that the most common cause of leaf damage in each season was overmature leaves. Additionally, it was found that during the rainy season, the highest number of leaves were trimmed due to leaf spot symptoms compared to other seasons. Regarding the percentage of loss, it was found that the summer season had the highest tendency of loss during cultivation, equaling 12.28±2.40%. Meanwhile, the rainy season had the highest tendency amount of trimming during harvesting, equaling 38.79±1.19%. However, it was found that the percentage of losses during the production and harvesting stages in each season was not significantly different. |
