The aim of this paper is to analyze energy patterns in open and greenhouse tomato production, since tomato is very important vegetable in human nutrition with tendency to be used whole year. Concerning the high energy consumption in greenhouse production a comparison with open field tomato production was found to be interesting. Data used in the study were obtained from the experiment carried out in a private property 140 km south from Belgrade (Serbia). In the study energy values were calculated by multiplying the amount of inputs and outputs by related energy conversion factors. The same tomato varieties were planted in open field and in the greenhouse at the same time.
