Resumen :
BACKGROUND: The current need to produce food for a growing population, from diminishing natural resources, such as
water and energy, and with minimum environmental degradation, demands the optimization of production. We compare the
economic feasibility of tomato production in an open system with a perlite substrate, a closed system with the nutrient film
technique (NFT), and a hydroponic crop (deep flow technique, DFT) using three levels of salinity that are found within the normal
range for irrigation water quality in southeastern Spain.
RESULTS: Production with DFT resulted in an increase in the cost of phytosanitary treatments and the cost of maintenance.
Production with perlite resulted in an increase in the cost of irrigation water and fertilization, and the use of NFT resulted in
an increase in energy costs. The point of price equilibrium was exceeded in the three soilless systems when using low salinity
water, and in perlite, with intermediate salinity water.
CONCLUSION: Profitability was reduced in the following order: perlite > NFT > DFT. There were positive results when using
irrigation water with low salinity, and in the case of perlite, with intermediate salinity. In every case, salinity reduced the
profitability of the operation, and this was greater when NFT was employed. The analysis of these soilless systems should be
continued to determine the possibility of reducing cultivation costs.
