• Resumo:

  Among the aromatical herbs, basil is of great economic importance in Brazil. This species is used as fresh herb and also for essential oil extraction. To evaluate the productivity of basil in protected environment, two species, Ocimum minimum L. (narrow leaf basil) and Ocimum basilicum L. (wide leaf basil) were cultivated under greenhouse conditions, using a hydroponic system and two types of substrata. The experiment was carried out in a completely randomized design with three repetitions. Samples were obtained during the flowering period. The yield and the chemical composition of the essential oils were evaluated. The highest yield of green mass from the two species, was obtained in the hydroponic system, with higher productivity (aprox. 44%) than the plants cultivated in prepared commercial substratum. Plants of Ocimum minimum L. produced more essential oil (aprox. 10%) than plants of Ocimum basilicum L. Significant differences were found in the chemical composition of essential oil between species. No differences were observed in the chemical composition of essential oil, comparing the three cultivation systems.
