Abstract:

 

This study was conducted to determine the balance between the inputs of energy and the energetic yield for hazelnut production in Turkey. The data for the study were collected from 30 hazelnut plantations. A total energy input of 43,790.57 MJ ha-1 was required for hazelnut production. Diesel-fuel, the single highest source of energy input, accounted for 44.78% of the total energy input. The two next highest energy sources were chemical fertilizers (36.94%) and farm manure (6.51%). The values of energy efficiency, energy productivity, specific energy, and net energy were 1.03, 0.04 kg MJ-1, 22.62 MJ kg-1 and 1,322.90 MJ ha-1, respectively. Estimations made by using econometric models showed that human labor, machinery, chemical fertilizers, pesticides, farm manure, electricity and water used for irrigation energy inputs had significantly positive effects on energy yield. The results of a sensitivity analysis of the energy inputs showed that the marginal physical productivity (MPP) value of human labor was the highest, followed by electricity and water for irrigation.
