“…Sage is a perennial crop and it is found that the essential oil is higher in the first cutting (in the end of spring) while the leaf yield is lower when the cultivation takes place at the end of summer [3]. It is cultivated worldwide but mainly found in Mediterranean basis [4][5][6]. The edible parts of Salvia officinalis are used for pharmaceutical, cosmetic and aromatic purposes [6,7].…”

Sage (Salvia officinalis L) is a widespread aromatic and medicinal plant with various positive affects in human diet and health. In order to investigate the interaction among bio-fertilization, plant density and irrigation regimes, in Salvia officinalis cultivation, an experimental field was established at the University Farm of Thessaly, in Velestino (Greece). The transplant was carried out in October 2016 and the experiment data concern the plant height, Leaf Area Index (LAI), Chlorophyll content and dry biomass of the 3 rd and 4 th growing years. A split-split-plot experimental design was used, including two irrigation regimes (IR0: no irrigation and IR1: irrigation), three bio -nitrogen fertilization systems (N0: 0 kg ha -1 , N1: 40 kg ha -1 , N2: 80 kg ha -1 ) and two different plant density (D1: 10.000 and D2: 20.000 plants ha -1 ). The use of the drip irrigation system ameliorated the plant height, the dry leaves yield and the LAI. The dry leaves yield in 3 rd year was ranged between 166.3 -522 kg ha -1 and 101.67 -359 kg ha -1 in May and August, respectively. As it concerns the Chlorophyll index (CCI), the bio -nitrogen fertilization and the irrigation had provoked an increase to its amount during the studied growing year. Therefore, Salvia officinalis can be a promising perennial crop, cultivated under the Greek climatic conditions.

“…Thus, it was established that the depth of tillage and the spacing of the crops are not of great importance for the formation of the productivity of clary sage under irrigated conditions. Moreover, Giannoulis et al (2021) proved that plant density had negative effect on the yields of a related species Salvia officinalis L., while their results support the claim of better crop productivity under mineral fertilisation. Katar et al (2022) also supports the statement that salvia productivity benefits from fertiliser application; however, essential oil yields could be decreased at higher rates of mineral nitrogen.…”

Ukraine has favourable natural conditions for the cultivation of medicinal and aromatic plants, but there is a lack of scientific knowledge and practical guidelines for their cultivation. Clary sage is a valuable and prospective crop for the South of Ukraine and deserves special attention. This study is aimed to investigate theoretical mechanisms of clary sage productivity formation on the irrigated lands of the Southern Ukraine. The experimental basis for the study is the data on crop inflorescence yields, collected during field investigation of clary sage cultivation technology in the dripirrigated lands of the Kherson Oblast during 2013-2018. Theoretical study on the yield formation depending on the cultivation technology elements was performed through rank correlation and heteroscedasticity analyses, while the mathematical model for the crop yield prediction was developed using multiple regression. As a result, the null hypothesis about the influence of the factors studied on crop yields was denied according to the Breusch-Pagan and Glejser tests, although the results of the analysis of variances revealed no significant effect of the depth of the plough and the spacing of the crop on the yields. Rank correlation analysis revealed that the highest influence on crop yield is attributed to phosphorus fertilisers. In addition, information on the influence of each agrotechnological factor on the yield of clary sage was determined, namely: 1 kg of nitrogen fertilisers applied per ha reduces the yield by 6.34 kg; 1 kg of phosphorus fertilisers applied per ha increases the yield by 156.44 kg; 1 extra cm of row spacing reduces the yield by 3.33 kg; 1 cm deeper ploughing improves the yield by 56.56 kg. The model has moderate fitting quality (correlation coefficient 0.5885) and reasonably good yield prediction accuracy (mean absolute percentage error 24.12%). The study has no analogues in Ukraine or in the world and provides novel theoretical and practical insights on the formation of clary sage productivity in the cold Steppe zone

Sage (Salvia officinalis L.) is a medicinal and aromatic plant (MAP) belonging to the Lamiaceae family. Its morphological, productive and chemical characteristics are affected by abiotic and biotic factors. The use of biostimulants seems to be one of the most interesting innovative practices due to fact they can represent a promising approach for achieving sustainable and organic agriculture. Despite a large application in horticulture, the use of biostimulants on MAPs has been poorly investigated. On this basis, a field experiment in a 2-year study was done to assess the effect of foliar treatments with different types of biostimulants (containing seaweeds, fulvic acids and protein hydrolysates) and two frequencies of application on morphological, productive, and chemical characteristics of S. officinalis grown organically in Mediterranean environment. Morphological, productive, and chemical parameters were affected by the factors. The biostimulant application generated higher plant height, chlorophyll content, relative water content, biomass yield and essential oil yield compared to control plants. In addition, more frequent application of biostimulants produced higher biomass and essential oil yield. The application of fulvic acid and protein hydrolysates every week produced the highest total fresh yields (between 3.9 and 8.7 t ha-1) and total dry yields (between 1.3 and 2.5 t ha-1). The essential oil yield almost doubled (33.9 kg ha-1) with a higher frequency of protein hydrolysates application. In this study, 44 essential oil compounds were identified, and the frequency factor significantly influenced the percentage of 38 compounds. The highest percentage of some of the most representative monoterpenes, such as 1,8-cineole, α-thujone and camphor, were observed in biostimulated plants, with average increases between 6% and 35% compared to control plants. The highest values for total phenolics, rosmarinic acid, antioxidant activity were obtained in control plants and with a lower frequency of biostimulant applications. This study emphasizes how biostimulant applications may be used to improve sage production performance and essential oil parameters when produced in agricultural organic system. At the same time, biostimulants application caused a decrease in total phenolic, antioxidant activity and rosmarinic acid values.
