“…The treatment of 200kg/ha of N resulted in the highest yield values, EO (%), p-cymene, limonene, dihydrotagetone, E-tagetone, Z-tagetone, Z-ocimenone, and E-ocimenone of Tagetes minuta (Omidbaigi et al, 2008b). The greatest biomass and EO composition of lemon grass herb were detected at a rate of 50kg (N)/hectare (Rashmi & Singh, 2008). Davana plants exposed to 94kg (N)/ha have enhanced growth and higher yields and EOs than those of the untreated control (Kumar et al, 2009).…”

Egyptian Journal of Botany http://ejbo.journals.ekb.eg/ 19 P RODUCERS in Egypt tend to use traditional methods of feeding medicinal and aromatic plants and separating the essential oils of bitter fennel from fruits only. However, they have not focused on other parts. This study was conducted to evaluate the essential oils of bitter fennel plants sprayed with L-phenylalanine and determine the possibility of using L-phenylalanine in the production of essential oils from bitter fennel parts. Bitter fennel exposed to different L-phenylalanine rates (0.0, 0.3, 0.6, 0.9, and 1.2g/L). Changes in essential oil sources (fresh and dry weights of herbs harvested at vegetative, flowering, and immature fruiting and dry weights of mature fruits) were recorded. Essential oils were extracted through hydrodistillation and analyzed through GC/MS. The greatest weights of plant parts and essential oil yields were recorded with 0.9 g/L. The main compounds were limonene and estragole. The highest values of limonene and monoterpene hydrocarbons were observed with the treatment of 0.6g/L L-phenylalanine in the flowering herb, whereas 0.3g/L L-phenylalanine produced the greatest value of estragole in mature fruits. The treatment of 0.9g/L L-phenylalanine produced the maximum value of oxygenated monoterpenes in mature fruits. The herb obtained in the immature fruiting period had the greatest value of sesquiterpene hydrocarbons under control treatment. Thus, this study could be used as a reference for selecting the suitable L-phenylalanine rate and bitter fennel part to produce essential oils based on the target constituents.

“…N affects EO metabolisms and their production through carbon assimilation and acetyl‐CoA formation via mevalonate pathway 27 . The EO has improved for many plants due to the presence of N; thyme, black cumin, coriander, anise, hyssop, davana, dill, Tagetes minuta , piper, sweet fennel, lemon grass and parsley EOs and their major constituents were significantly improved in response to N 28–38 . Some past researches have indicated that S has a positive effect on the yield and composition of basil and wild marigold EOs 23,39,40 …”

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.

“…This is thought to be because the nutrients needed by plants are not yet available, considering the slow nature of compost. Based on research results [11] When 75 kg/ha of potassium was applied, the percentage of essential oil dropped to 0.63%, The highest percentage of essential oil (0.72%) was found in plants that were given 25 kg of nitrogen and 50 kg of potassium per hectare. So there is no real difference between plants given compost and those not given compost.…”

This study aims to determine the effect of potassium fertilizer and compost of Empty Palm Oil Bunches (EFB) on the growth of citronella (Cymbopogon nardus L.). The research was started in February-June 2022 at BPTP Banten, and the Laboratory of the Department of Agroecotechnology, Sultan Ageng Tirtayasa University. This study used a factorial Randomized Block Design (RBD) method which consisted of two factors. The first of potassium fertilizer dose has 4 levels, 0 kg/ha potassium (K0), 15 kg/ha (K1), 30 kg/ha (K2) and 45 kg/ha (K3). The second factor of EFB compost has 4 levels, 0 tons/ha (T0), 20 tons/ha (T1), 30 tons/ha (T2) and 40 tons/ha (T3). The results showed the dose of potassium fertilizer 30 kg/ha gave the best results on plant height parameters at the age of 3, 4, 5, 6 weeks after planting (WAP). Dosage of 40 tons/ha of EFB compost gave the best results on the number of leaves aged 5 and 6 WAP. There was no interaction between the dose of potassium fertilizer and the dose of EFB compost on all.
