Journal Article The purpose of this work was to analyse the energy productivity and efficiency of agricultural enterprises growing poppy. The number of enterprises investigated in the study was determined from a stratified random sample of 87, the data is from 2019, and the study was conducted in Turkey. All inputs and outputs used in poppy production were obtained by multiplying energy equations with conversion coefficients in determining the energy use of the enterprises. Data Envelopment Analysis (DEA) method was employed to calculate the technical, pure-technical, and scale efficiency of poppy-producing enterprises. Poppy energy inputs consisted of the use of human labour, machinery, fertilizer, pesticides, seeds, water, and fuel. The poppy capsule yield per unit area was regarded as the energy output. In the end, 40.23% of the total energy input in poppy production consisted of direct and 59.77% indirect energy. Non-renewable energy consumption (88.70%) was found to be rather high in the research area. Therefore, the use of chemical fertilizers and fuels, which are non-renewable energy sources, must be lessened for poppy plant production. The energy efficiency was found to be 0.08 in poppy production. According to this result, the production systems of the enterprises producing poppy are sufficient and energy is used efficiently. The specific energy value in the enterprises was calculated as 11.95 MJ kg-1 and the Technical Efficiency (TE) was calculated as 0.683. Producers produce at the same level with 68.3% of their capital, and 31.7 % saving. https://jast.modares.ac.ir/article_16884_96ddc5dc8fec52547e2b998e85bd2628.pdf
