Energy efficiency of the open field and greenhouse tomato production

Abstract

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. The greenhouses used were one tunnel structure, covered with double PE film, 5 x 20 in and one gutter-connected double PE covered structure 2 l m wide and 250m long. The results obtained lead to the conclusion that lower specific energy per production surface can be expected in conditions of the open field and that, regarding the greenhouses lower value for energy consumption can be expected in case of multi-span greenhouses.
