The effects of different boron doses (boron-free, pure boron, diluted in 1/2 and1/8 ratios) on the ratio and quality of essential oil in medicinal sage (Salvia officinalis L.) during the years 2016 and 2017 were investigated. Field trials were conducted with the randomized block design in triplicates. The essential oil of S. officinalis L. was obtained by gas chromatography/mass spectrometry (GC–MS) with flame ionization detection (FID). The required measurement could not be taken at the pure dose application because the plants were damaged. In the analysis carried out on dry leaf, the main components of essential oil were found as follows: α-thujone 32.99%; 1.8-cineol 17.41% for the boron-free dose; viridiflorol 24.25%, manool 15.28% for the 1/2 boron dose, and lastly, α-thujone 32.31%, camphor 14.23% for the 1/8 boron dose. Some boron doses had a positive effect on the essential oil yield and essential oil components. In this study, different compounds were obtained with different boron dose applications. The dose to be recommended is the 1/8 boron dose since it has the minimum toxic effect on the plants and a positive effect on the essential oil yield and quality as general.
