TL;DR: Sudha et al. as discussed by the authors conducted a field trial with six different combinations of organic manure (FYM and Vermicompost) and inorganic fertilizers [nitrogen-phosphorus-potassium (NPK)] to study their effect on yield and oil quality in basil (Ocimum basilicum L. cv.
Abstract: Intensive cropping systems with fertilizer responsive crops that rely on high input of inorganic fertilizers often lead to nonsustainability in production and also pose a serious threat to soil health. Application of organic sources of nutrients with no or very little use of fossil fuel‐based inorganic fertilizers is rapidly gaining favor. However, considering economics and also physiological potential of varieties, entire dependence on organic sources of nutrients may not be adequate to attain the most productivity. Integrated nutrient management with both organic and inorganic fertilizers was investigated. A field trial was conducted with six different combinations of organic manure (FYM and Vermicompost) and inorganic fertilizers [nitrogen‐phosphorus‐potassium (NPK)] to study their effect on yield and oil quality in basil (Ocimum basilicum L. cv. Vikas Sudha). Results from the experiment revealed that among the six treatments compared, the combination of Vermicompost at 5 t ha−1+fertilizer NPK...

TL;DR: The compensatory effect of chitosan in reducing the negative impact of stress conditions on dry matter and oil yield was due mainly to stimulation of osmotic adjustment through proline accumulation and reduction of lipid peroxidase level, which increased the integrity of cell membranes of thyme leaves.
Abstract: Thymus daenensis , a perennial herb, is often grown in areas that experience drought conditions during its growing period. Application of chitosan may compensate for the negative impact of drought stress on the yield of oil and secondary metabolites in Thymus . The interactive effects of foliar application of chitosan and drought stress on dry matter, essential oil yield, and selected physiological characteristics including photosynthetic pigments, osmotic adjustment, and lipid peroxidation of Thymus were investigated in a two-year study from 2014 to 2015. Treatments consisted of 0, 200, and 400 μL L − 1 chitosan applied to plants grown under field capacity, mild drought stress (50% field capacity), and severe drought stress (25% field capacity). Dry matter yield decreased substantially as drought stress intensified. However, essential oil content increased under stress conditions, with the highest essential oil yield obtained from plants under mild drought stress. Foliar application of chitosan compensated to some extent for dry matter and oil yield reduction of plants grown under drought stress. The highest essential oil yield (1.52 g plant − 1 ) was obtained by application of 400 μL L − 1 chitosan under the mild stress condition in 2015 when plants were mature. The compensatory effect of chitosan in reducing the negative impact of stress conditions on dry matter and oil yield was due mainly to stimulation of osmotic adjustment through proline accumulation and reduction of lipid peroxidase level, which increased the integrity of cell membranes of thyme leaves.

TL;DR: This study suggests for the first time the ability of S. perfoliata, S. thymbra, L. nobilis and P. palestina essential oils and some identified terpenes to inhibit human tumor cell growth.
Abstract: Background: The aim of this work was to study the cytotoxicity of essential oils and their identified constituents from Sideritis perfoliata, Satureia thymbra, Salvia officinalis, Laurus nobilis and Pistacia palestina. Materials and Methods: Essential oils were obtained by hydrodistillation and were analysed by gas chromatography (GC) and GC/mass spectrometry (MS). The cytotoxic activity was evaluated in amelanotic melanoma C32, renal cell adenocarcinoma ACHN, hormone-dependent prostate carcinoma LNCaP, and MCF-7 breast cancer cell lines by the sulforhodamine B (SRB) assay. Results: L. nobilis fruit oil exerted the highest activity with IC50 values on C32 and ACHN of 75.45 and 78.24 Ig/ml, respectively. The activity of S. perfoliata oil on both cell lines (IC50 of 100.90 mg/ml for C32 and 98.58 Ig/ml for ACHN, respectively) was also interesting. Among the tested constituents the highest activity was found when ·-humulene was applied to LNCaP cells (IC50 of 11.24 Ig/ml). Conclusion: This study suggests for the first time the ability of S. perfoliata, S. thymbra, S. officinalis,
