The objectives of this study were to conduct an economic analysis of plum production, identify input-output energy use, and explore energy consumption efficiency in relation to various training systems and planting densities. To that end carried out an economic analysis of plum production according to training systems and planting distances and determined energy efficiency. The research was conducted in the Eğirdir district of Isparta province, Türkiye using the ‘Angeleno’ cultivar grafted on the ‘Myrobolan 29C’ rootstock in 2018 and 2019. A split plot in a randomized block design was employed, with slender spindle and V trellis training systems and four different planting distances (80 cm, 120 cm, 160 cm, and 200 cm). The results indicated variations in energy input-output and profitability based on the training systems and planting distances. Energy input varied between 16,806.37 MJ ha-1 and 18,576.17 MJ ha-1, and energy output between 30,970.00 MJ ha-1 and 50,468.75 MJ ha-1. Fertilizer, electricity, pesticide, and diesel were identified as the most energy-consuming inputs across all treatments. The highest energy efficiency was obtained in the slender spindle-80-cm treatment, with a value of 2.72, while the lowest energy efficiency was recorded in the V trellis-200-cm treatment, with a value of 1.84. The economic analysis revealed that plum cultivation is a viable investment option for all training systems and planting distances. Although positive net profits were observed in all treatments, the slender spindle-80-cm treatment yielded the highest net profit. However, increasing energy consumption as net profit increases poses a significant challenge. Therefore, it is crucial to support initiatives aimed at addressing this issue.
