Abstract
Mint (Mentha piperita) has extensive uses in food and drug technology.
Mint essential oil is one of the most applicable essential oil at the world.
Menthol, as peppermint essential oil, has anti-bacterial properties and is used in throat and mouth washing solutions.
Also it has anti-inflammatory effect.
In order to investigate different levels of nitrogen and potassium in Johnson solution on essence amount of peppermint (Mentha piperita) an experiment was carried out during 2006–2007 in mashhad weather condition.
The treatments included N in five levels (105, 135, 165, 195 and 225 ppm) and k in three levels (138, 178 and 218 ppm) with three replications.
The statistical design of the experiment was factorial based on completely randomized blocks design.
Peppermint plants were grown in sand media under open-air soilless culture condition and the system was bag culture method.
The results showed that the highest essential oil production was in N at 195 ppm and K at 218 ppm concentration.
The optimal level of nitrogen and potassium for peppermint growing in open-air hydroponics according to the results was, respectively, at 195-225 and 178-218 ppm.
