Abstract :
Medicinal plants are of great value and importance in providing health care for communities in terms of treating and preventing diseases. Peppermint is one of the most important medicinal plants belonging to the Lamiaceae family which is cultivated worldwide today. Extensive research has been started to find out the effectiveness and effect of manure and biological fertilizers on the growth, yield and production of essential oils of medicinal plants which suggests improving the quality and quantity of the crops. In order to investigate the effects of livestock manure and biological fertilizers on peppermint mint, a factorial experiment in a completely randomized design with 4 replications was conducted in pots in Varamin region in 1396. Treatments included three levels of manure (0, 3 and 5 g cattle manure per 1 kg of soil) and four levels of biological fertilizers (no use, nitroxin, Barvar-2 and their composition). The results showed that the effects of livestock manure and biological fertilizer on the most of measured traits were significant. Comparison of mean of traits showed that usage of 5 grams of manure per one kg of soil, as well as biofertilizer application of nitroxin and Barvar2 had the highest significant increase in plant height, root length, fresh and dry weight of leaves per plant, fresh and dry weight of the plant, Chlorophyll b in leaf, essential oil content, nitrogen and phosphorus in leaf, essential oil yield and menthol content in essential oil compared to control; Therefore, the consumption of manure (5 grams of manure per one kg of soil) and use of the combined biological fertilizers are recommended for the highest growth yield, essential oil yield and menthol content.
