Abstract
The aim of the study is to determine the energy consumption (plant protection products, fertilizers, diesel oil, machinery, human power etc.) of three directions of mid-early tomato production for South Central region in Bulgaria.
The total energy consumption in indeterminate tomato production is 76.65*103 GJ but in determinate tomato production are 78.07*103 GJ for seedlings technology and 73.47*103 GJ for the growing by direct sowing.
The energy input of chemical fertilizers (19.13–20.33%), mainly nitrogen, has the biggest share in the total energy inputs followed by manure (19.41–20.63%), plastics products (17.98–19.11%) and diesel (12.06–18.27%). The physical quantities of the inputs form a total production cost price of 0.34 lv/kg, 0.33 lv/kg and 0.24 lv/kg, respectively.
The obtained results indicate that the mid-early tomato production is based on non-renewable energy – from 63.52 to 72.69% of the total energy inputs.
