“…Increased growth and development in plants fertilized with higher concentrations of macronutrients or inoculated with PGPR have been reported for several species (Egamberdieva and Teixeira da Silva, 2015;Orhan et al, 2006;Fan et al, 2017). The data obtained displayed that the effects of nitrogen and sulfur fertilization on sweet basil are consistent with previous reports with fresh biomass showing an increasing trend as determined by micronutrients supplementation (Zheljazkov et al, 2008;Kiferle et al, 2011;Oliveira et al, 2014). Indeed, N fertilization has already been shown to be one of the pivotal factors affecting basil yield (Zheljazkov et al, 2008).…”

Nutraceutical Profiles of Two Hydroponically Grown Sweet Basil Cultivars as Affected by the Composition of the Nutrient Solution and the Inoculation With Azospirillum brasilense

Sweet basil (Ocimum basilicum L.) is one of the most produced aromatic herbs in the world, exploiting hydroponic systems. It has been widely assessed that macronutrients, like nitrogen (N) and sulfur (S), can strongly affect the organoleptic qualities of agricultural products, thus influencing their nutraceutical value. In addition, plant-growth-promoting rhizobacteria (PGPR) have been shown to affect plant growth and quality. Azospirillum brasilense is a PGPR able to colonize the root system of different crops, promoting their growth and development and influencing the acquisition of mineral nutrients. On the bases of these observations, we aimed at investigating the impact of both mineral nutrients supply and rhizobacteria inoculation on the nutraceutical value on two different sweet basil varieties, i.e., Genovese and Red Rubin. To these objectives, basil plants have been grown in hydroponics, with nutrient solutions fortified for the concentration of either S or N, supplied as SO 4 2− or NO 3 − , respectively. In addition, plants were either non-inoculated or inoculated with A. brasilense. At harvest, basil plants were assessed for the yield and the nutraceutical properties of the edible parts. The cultivation of basil plants in the fortified nutrient solutions showed a general increasing trend in the accumulation of the fresh biomass, albeit the inoculation with A. brasilense did not further promote the growth. The metabolomic analyses disclosed a strong effect of treatments on the differential accumulation of metabolites in basil leaves, producing the modulation of more than 400 compounds belonging to the secondary metabolism, as phenylpropanoids, isoprenoids, alkaloids, several flavonoids, and terpenoids. The primary metabolism that resulted was also influenced by the treatments showing changes in the fatty acid, carbohydrates, and amino acids metabolism. The amino acid

“…Composition of Urea fertilizer 80% + ZA 20% and the frequency of fertilization every one week gave the highest effect on the fresh and dry weight of rootsshoots (Table 5). The growth of basil plants can be increased by providing fertilizers that have the perfect balance of Nitrogen and Sulphur (N:S) (Oliveira et al, 2014). Zenda et al (2021) mentioned that the optimum ratio of nitrogen and sulfur in the soil was 7:1.…”

Basil is a plant that can be cultivated in Psamment (coastal sandy soil). Basil requires nitrogen (N) and sulfur (S), so the N-S balance is needed to obtain optimal results. Psamment contains low colloid, causing nutrients to be barely bound and easily lost. Zeolite and biochar can be a solution. This study aimed to determine the composition and frequency of fertilization, as well as the use of soil amendment for basil growth. This research consisted of two interrelated studies arranged in a Randomized Complete Block Design. The research was conducted in Bugel, Panjatan, Kulon Progo, and the analysis was performed at the Soil Department Laboratory, Faculty of Agriculture, Universitas Gadjah Mada. The first study consisted of two factors, namely Urea-ZA composition (0:0, 60:40, 70:30, 80:20, 90:10, and 100:0) and frequency of fertilization (every 1 and 2 weeks). The application of Urea-ZA (80:20) gave the best fresh-dry weight, N-S content, and N-S uptake of basil, and this result was used as the reference for the second study. The second study consisted of two factors, namely Urea-ZA fertilizer doses (50%, 75%, and 100%), and types and doses of soil amendment (without amendment, zeolite 7.5 t/ha, zeolite 15 t/ha; biochar 7.5 t/ha, and biochar 15 t/ha). It can be concluded that soil amendments application improved the chemical properties of psamment, fresh-dry weight, N-S content, and N-S uptake of basil. Furthermore, biochar and zeolite could increase the effectiveness of fertilization, so the dose of Urea-ZA fertilizer could be reduced until 50%.

Coriander essential oil has several biological characters those make it an important place as a source of natural product. Due to the lack of natural products, many essential oil compounds are imitated by others made of cheap chemicals, which studies have shown to have a great danger to human health. From this point of view, it is necessary to search for new ways to increase natural products, the most important of which are essential oils. One of these methods is the use of bioregulators to modify the production of essential oil and its components to increase its biological use area. Thus, the variations of coriander green fruits essential oil were evaluated under different rates of glutathione and α‐tocopherol to determine the possibility of using them in the production of essential oil from coriander green fruits. Coriander plants were treated during cultivation at rates of glutathione (0, 0.2, 0.4 and 0.6 g L−1) without or with α‐tocopherol (0.4 g L−1). Green fruits essential oil was separated by hydro‐distillation and analysed by gas chromatography and gas chromatography/Mass spectrometry; data were statistically analysed by two ways analysis of variance. Plants treated with 0.6 g L−1 glutathione with α‐tocopherol gave the maximum values of green fruits yield and essential oil content (% and yield per plant). The major essential oil constituents were linalool, undecan‐3‐ol and yomogi alcohol; while oxygenated monoterpenes were the main fractions. Plants exposed to glutathione with α‐tocopherol doses resulted in higher values of major components and main fraction than those subjected to glutathione rates. This trial ascertained that the subordination of coriander plants to glutathione and α‐tocopherol rates led to variations in green fruits essential oil, and this, in turn, affected its biological activities.
