“…Currently, many literature reports focus on the effect of abiotic stress on the composition of lavender essential oil [ 9 , 10 , 11 ], as well as genetic factors [ 12 ], while few works have dealt with the effect of the ontogenetic development [ 13 , 14 ]. However, other essential oil-bearing plants have demonstrated the influence of the endogenous “plant age” factor on EO yield and composition [ 15 , 16 , 17 ].…”

Lavandula angustifolia Mill., known as one of the best essential oil-bearing plants, is an aromatic plant that is well cultivated in many Mediterranean regions due to its adaptability to variations in climatic and edaphic conditions. Therefore, its essential oil (EO) composition and its antimicrobial activity change as a consequence of abiotic and biotic factors. The chemical composition of L. angustifolia EO collected during four consecutive years of growth was one of the aims of this work. The volatile profile evidenced the prevalence of linalool and linalool acetate even though they switched their positions according to age. Plants in their first year were characterized by a high amount of sesquiterpene compounds (22.1% of the identified fraction). This percentage decreased during plant growth, not representing more than 5.3% in the fourth year. It is interesting to note that both the third- and fourth-year plants showed a content of monoterpenes that exceeded 90% of the total identified constituents. The EO extracted from the oldest plants evidenced higher activity on the studied strains, with more sensitivity on the Gram-positive ones. Tuscan lavender EO, especially that obtained from the four-year-old plants, is of great interest for its potential industrial applications and constitutes an example for the valorization of marginal Tuscan land and good-quality production.

“…Many reports on diverse plant species indicated that biomass yield and secondary metabolites content of medicinal and aromatic plants were improved when combined synthetic and organic fertilizers were applied (Fallah et al., 2020; Keshavarz Afshar et al., 2014; Mavandi et al., 2021; Onofrei et al., 2017). Positive responses of various species of medicinal herbs, including rosemary ( Rosmarinus officinalis L.) (Tawfeeq et al., 2016), basil (Pandey et al., 2016), and geranium ( Pelargonium graveolens L'Hér.…”

“…For example, Rezaei et al (2019) concluded that application of CM resulted in higher dry matter yield and aroma profile of the creeping savory (S. spicigera). Recently, Mavandi et al (2021) reported that a combination of VC and CM had more positive effects on plant growth and yield of lavender (Lavandula angustifolia Mill. )…”

Productivity of medicinal and aromatic plants refers to their biomass and the target chemical constituents' quantity. A 2‐yr field study was laid out as a split‐plot to evaluate the effectiveness of the exogenous chitosan and fertilizer type on biomass, biochemical characteristics, and phenolic compounds of Thymus daenensis Celak. (denaian thyme, from the mint family). Mainplots consisted of fertilizer type, including synthetic fertilizer (Syn), cow manure (CM), vermicompost (VC), and a combined fertilizer. Foliar application of chitosan at three concentrations (0, 200, and 400 mg L–1) was allocated to subplots. Thyme responded differently, based on its stage of growth. In the establishing year, Syn, and 400 mg L–1 chitosan produced 2,047 kg ha–1dry matter. In the harvesting year, maximum biomass (2,853 kg ha–1) was obtained from the combined fertilizer and 400 mg L–1 chitosan. Accumulation of nutrients was in the order of K > N > P. The highest nutrient accumulation was obtained when combined fertilizer was used. Exogenous chitosan at the rate of 400 mg L–1 boosted nutrient density in leaves. Inboth growing seasons, all phenolic compounds were influenced by fertilizer and chitosan application. Cinnamic acid and rosmarrenic acid were the major phenolic compounds. In the establishment year, major and minor phenolic compounds were highest when CM was applied. Phenolic compounds reached their peak concentration in the harvest year in combined fertilizer treatment. The interactive effects of fertilizer and chitosan on phenolic compounds were minimal in both growing seasons. Combined organic and Syn and chitosan seemed an effective strategy to improve biomass yield, phenolic compounds, and nutrient density in thyme.

seaweed has developed as a cure with the capability to spare the biological system, because of its eco-friendliness, reasonableness, accessibility, and active ion expulsion rate. This work summarizes the result of saltiness on the organ of plants, and this biomass is revered because the driving redress material among the accessible materials too grandstand the bio activity part of seaweed extricate disengage and its adequacy as a valuable, on morphological and physiological characteristics of peppermint underneath completely different irrigation water salinity was conducted a factorial experiment supported a totally irregular style with four replications within the Yazd University greenhouse in 2020. Experimental factors included salinity stress at four levels of (0, 2, 4 and 8 dS/m) and, seaweed powder application at four levels of (0, 1, 2 and 4 ppt ). Morphological traits or growth parameters and physiological characteristics (relative water content, photosynthetic pigments, total soluble carbohydrate, proline amino acid) assessed. our results demonstrated that seaweed led to changes in peppermint growth and physiology which improved the plant salt stress response. Examination of interaction effects showed was a significant effect on total chlorophyll, chlorophyll a, chlorophyll b, carotenoids (Photosynthetic pigment) and, total soluble carbohydrate at the level of 1% (p≤0.01), and in examining morphological traits results demonstrated that fresh and dry weight of leaves, aerial components, total fresh and dry biomass and harvest index were significant at the level of 1% (p≤0.01). The use of seaweed at 4 ppt under stress-free conditions resulted in the highest weight of leaves, aerial, and total biomass. The highest relative water content was related to the without salinity stress (65.8%). The highest proline content was obtained at 4 and 8 dS/m salinity levels, which showed a rise of 37.5% compared to the management treatment. In general, the results showed that the employment of 2 and 4 ppt seaweed at high levels of salinity (4 and 8 dS/m) reduced the adverse effects of salinity stress by improved physiological traits, together with chemical change pigments and amino acid content. This analysis grandstands the bio activity part of seaweed growth biomass and its adequacy as a helpful, cheap, and reasonable.
