Impacts et analyse technico-économique de différentes conduites climatiques en tomate hors-sol sous serre

Abstract : New systems are regularly developed to improve greenhouse’s crop production. In this study, the profitability of two systems is examined: an active ventilation system (AVS) from Van Dijk company and a Ultraclima® semi-closed greenhouse from Kubo company. This trial has been conducted in the region of Nantes, France. These two materials allow a running cost’s decrease. Results showed that AVS is able to save about 1,51€/m² on this cost at the end of a soilless tomato crop mainly because of a reduction of gas consumption. A semi-closed greenhouse allow a running cost’s save of 0,86€/m². Yet, the semi-closed greenhouse is able to significantly increase production which results in an increase of the turnover. Thus, an approximate gain of 4,49€/m² is possible with this greenhouse. However, the purchase cost of this greenhouse is about 30€/m² more than a traditional greenhouse. The purchase cost of the AVS is about 10€/m². This means an investment in an AVS doesn’t seem to be profitable for a grower because he must wait 8 years to absorb his expense. On the contrary, an investment in a semi-closed greenhouse could be profitable because the expense will be absorbed in less than 6 years and the future profits will be important.
