“…The accumulation of macronutrients N, P, K are limiting factors which had a role particular on plant metabolism, as well known forming of tissue, organs, and converting primary products to secondary metabolism. Indeed, nutrient status such as nitrogen content in leaves and accumulation of monoterpenes, such as citronellal, citronellol, and geraniol, were influenced by the availability of soil nutrients and nutrient accumulation in leaves [19]. In this case, the nutrients include an essential macro nutrient, as nitrogen.…”

Cymbopogon nardus is an aromatic plant which produces essential oil. Citronellal, citronellol, and geraniol as well-known as monoterpenes. The component of monoterpenes in this research were triggered by organic matter, such as organic manure and rhizobacteria. Organic fertilizers are used for environmentally friendly by maintaining soil and plant health and it’s necessary to achieve agricultural sustainability. Rhizobacteria are beneficial microorganisms for plants and soil for environmental management of both soil, plants, and soil micro biodiversity. Rhizobacteria contributes to soil fertilization through bio-fixation and bio-solubilization of essential nutrients along with the production of growth regulators. Microorganisms regulate the mechanism of absorption and mobility of nutrients in soil. The objective of this research is to investigate the effects of rhizobacteria and organic manure on the component of monoterpenes as well as the content of citronellal, citronellol, and geraniol. The results research show that C. nardus treated with rhizobacteria accumulating of nitrogen 1% and geraniol 5% in leaves which is more than those without rhizobacteria. Interestingly, content of citronellal and citronellol in leaves increased reach at 10% treated by without rhizobacteria and it higher than those supplied with rhizobacteria. In that case, citronellal, citronellol, geraniol formed from the carbon which was seems supplied by organic manure. Furthermore, rhizobacteria treatment shows a stable content of oil components in various rates of organic manure, but able to increase the oil yield at about 30% of C. nardus. Meanwhile, without supply of rhizobacteria, the result of oil yield relatively similar in various rates of organic manure. Regarding to the results, found that application of rhizobacteria able to increase the fresh weight, dry weight, and oil content. As consequently, contribution of rhizobacteria and organic manure to the mechanism of mineralization and improve soil health indirectly. Hence, plant able to uptake and accumulation nutrients in particular nitrogen, phosphorous and potassium.

Background Biodynamic agriculture and the use of plant growth-promoting bacteria (PGPBs) have been demonstrated to offer various benefits for achieving agricultural sustainability. The aim of this study was to evaluate the effects of PGPBs Azotobacter and Azospirillum, compost, and compost with biodynamic preparations (BD) on the essential oil (EO) characteristics of lavender under salinity stress. Research methods The experiment was carried out in a greenhouse for 2 years and involved three factors: four PGPBs, three types of compost, and three levels of salinity stress. Results The results indicated that the essential oil (EO) characteristics increased with 50 mM NaCl but decreased with 100 mM NaCl. Salt stress reduced the cell membrane stability (CMS) and auxin content, while increasing proline contents. However, the application of PGPBs, compost, and compost with biodynamic preparations had an opposite effect on CMS, auxin, and proline parameters compared to salt stress. Based on the results, the treatment that combined compost + BD with Azotobacter was found to be the most effective in enhancing the EO characteristics under both mild and severe salinity stress conditions. Conclusions The results of this study suggest that compost, biodynamic compost preparations, and PGPBs could be useful in enhancing the EO in medicinal plants and alleviating the adverse effects of salt stress on plants.
