CARRASCO, Gilda; RAMIREZ, Patricia  y  VOGEL, Hermine. EFFECT OF THE ELECTRICAL CONDUCTIVITY OF THE NUTRIENT SOLUTION ON YIELD AND ESSENTIAL OIL IN BASIL GROWN BY NFT. Idesia [online]. 2007, vol.25, n.2, pp.59-62. ISSN 0718-3429.  http://dx.doi.org/10.4067/S0718-34292007000200007.

Basil (Ocimum basilicum) is an aromatic plant commonly used for seasoning. The effect of different solutions in Nutrient Film Technique (NFT) was studied to avoid microbial contamination and to offer basil from culture in a cold greenhouse during the winter months. Different electrical conductivities of nutrient solutions were applied between October and January in Talca, Chile. The treatments consisted of incremental electrical conductivities (EC) of the nutrient solutions with 1.5, 3.0 and 4.5 dS/m in a randomized block design with three replicates. Basil plants grown at 1.5 dS/m of nutrient solution showed a higher total fresh matter (110.33 g/ plant), root fresh matter (29.13 g/plant) and essential oil yield(0.4 ml/m2), whereas the essential oil concentration was similar for all treatments.

Palabras clave : Soilless culture; nutrient solution; Ocimum basilicum.
