Abstract
To study the effect of different levels of nitrogen (0, 70, 140, and 210 mg/L) on growth, some biochemical characteristics and nutrient uptake (nitrogen, phosphorus, and potassium( of sage under hydroponic conditions, a greenhouse experiment was conducted based on a completely randomized design with four replications in greenhouse research of the Ferdowsi University of Mashhad in 2019. The mean comparison results showed that, with increasing nitrogen levels, the plant's growth characteristics increased which 210 mg/L N level compared with no N application caused to decrease by 54.19%, 72.59%. 39.49%, 82.52%, 51.42%, 72.20%, 71.46%, 95.17%, 90.31%, 95.82%, 92.30%, and 83.46% of stem diameter, number of branches, number of nodes, number of leaves, intermediate length, leaf length, leaf width, stem fresh and dry weight, fresh and dry weight of aerial parts and the ratio of the dry weight of aerial part to dry weight of root, respectively. Application of 210 mg/L nitrogen increased the RWC, proline, and essential oil content by 9.57%, 266.6%, and 14.87%, respectively, and decreased 30.45% and 51.51% electrolyte leakage and malondialdehyde compared with the nitrogen omission. Also, at the lowest N level N, P, and K content were decreased by 56.89%, 85.13%, and 32.65%, respectively compared with the highest N level. This experiment showed that different N levels can result in different effects on the growth and essential oil content of sage. In this study, the results have shown that the application of 210 mg/L N had the greatest effect on improving the studied traits in sage and its use could be recommended.
