Field experiments were carried out during Kharif season of 2015 and 2016 to study the influence of FYM, inorganic fertilizers and bio-fertilizers on fresh herbage yield, quantity and quality of essential oil of sweet basil (Ocimum basilicum). Nine treatments with  three replication were adopted in a randomized block design to find out the effect of different levels of N applied through FYM (100, 75 and 50% of the recommended N along with and without bio-fertilizers), recommended dose of NPK (160:80:80 kg ha-1), recommended FYM (10 t ha-1) + NPK (160:80:80  kg ha-1) and control (recommended  FYM (10 t ha-1) on fresh herbage and oil yield, oil content and oil quality of sweet basil (Ocimum basilicum L.). Pooled results revealed that application of recommended FYM (10 t ha-1) along with recommended NPK (160:80:80 kg ha-1) recorded the highest fresh herbage yield (39.95 and 19.37 t ha-1), essential oil content (0.48 and 0.45%) and essential oil yield (199.7 and 107.58 kg ha-1) in the main crop and ratoon, respectively. With respect to oil quality, bio-fertilizer has a good impact on oil quality, that highest percentage of Methyl chavicol was recorded with application of recommended FYM (10 t ha-1) + recommended N through FYM along with bio fertilizers in the main crop of 2016 (63.78%) and in the ratoon (59.39 and 59.67%) of 2015 and 2016, respectively.

<p><span>A field experiment was conducted to evaluate yield and some qualitative characteristics of four cultivars of sweet basil treated with different levels of nitrogen fertilizer. The experiments were located on the Agricultural Research Station of Khorramabad, Iran, during the 2016-2017 growing season. Treatments were arranged in factorial split-plot-in time in randomized complete block design with three replications. Experimental treatments were four cultivars of sweet basil (<em>Ocimum basilicum</em> ‘Italian Large Leaf’, <em>O. basilicum</em> ‘Mobarakeh’, <em>O. basilicum</em> ‘Cinnamon’ and <em>O. basilicum </em>‘Thai’), three levels of nitrogen fertilizer (0, 100 and 200 kg ha<sup>-1</sup> urea) and three harvests. The highest total dry mass (3482.4 kg ha<sup>-1</sup>) was related to ‘Italian Large Leaf’ with the application of 200 kg ha<sup>-1</sup> urea at the second harvest. The maximum (26.79 kg ha<sup>-1</sup>) essential oil yield belonged to 100 kg ha<sup>-1 </sup>urea. The highest concentrations of main constituents of essential oil, except methyl chavicol, 1,8-cineole and methyl cinnamate were obtained by control (without nitrogen fertilizer). Italian Large Leaf cultivar and application of 100 kg ha<sup>-1</sup> urea are recommended to access an acceptable agricultural yield and essential oil yield in sweet basil under the environmental condition similar to Khorramabad</span></p>

Basil is an aromatic, medicinal, culinary, and multifunctional herb which is grown in different parts of Ethiopia. Although the oil distilled from the herb, as well as its herbal yields, are a crucial input in the pharmaceutical industry and for culinary purposes, the yield obtained is below its potential due to various challenges. Genotype and plant spacing are two of the factors which contribute to the low production of the crop. A field trial was conducted at Jimma University College of Agriculture and Veterinary Medicine (JUCAVM) in 2016 and 2017 to assess the effect of genotype and plant spacing on essential oil yield and other yield-related traits of this important herb. Four promising genotypes (BO-1, BO-3, BO-4, and BO-5) and three plant spacings (20, 30, and 40 cm) were studied in a 4 × 3 factorial design arranged as randomized complete blocks (RCBD) with three replications. Data on plant height, leaf area, number of primary branches, essential oil content and oil yield were collected and analyzed. The analysis of variance revealed that there were highly significant (<em>p</em> &lt; 0.01) interaction effect of genotype with plant spacing for all parameters tested. The maximum essential oil yield (7.88 kg ha<sup>−1</sup>) was obtained from genotype BO-5 at 30 cm spacing, whilst the least (2.68 kg ha<sup>−1</sup>) was recorded from BO-1 at 40 cm spacing. The maximum oil content (101 mL g<sup>−1</sup>) was gained from BO-1 at 20 cm, but BO-3 at 30 cm spacing recorded the least oil content though there were no significant differences between the three treatment combinations. Further studies at different locations and seasons will be important to for future local recommendations.

 Field experiments were conducted at ICAR - Indian Institute of Horticultural Research, Bengaluru during Kharif season of 2015 and 2016 with nine treatments and three replications in a randomized block design to find out the effects of integrated nutrient management on Quantity and Quality of essential oil of basil (Ocimum basilicum) . The results revealed that combined application of recommended FYM (10 t ha-1) and NPK (160:80:80 kg ha-1) registered the highest oil yield in the main crop (211.94, 187.46 l ha-1) and in ratoon (144.36, 70.81 l ha-1) during 2015, 2016, respectively. For oil quality, the main constituents of basil essential oil have been reported and the result showed that chemical compositions of the essential oil for sweet basil were affected by fertilizers in the maincrop and ratoon during two years of the experiment. In general, application of NPK (160:80:80 kg ha-1) + FYM (10 t ha-1) i.e., T9 recorded the best quality. The results obtainedfrom this study demonstrated that integrated nutrient management can maximize nutrient absorption as a result of increased soil fertility which reflected on oil yield and quality.

Sweet basil (Ocimum basilicum L.) and holy basil (Ocimum sanctum L.) are the most widely grown basil species in the world either for the fresh market or for essential oil production. Both species are considered to be promising essential oil crops in the southeastern United States; however, research on oil production and composition of these species in Mississippi and the southeastern United States is lacking. The objective of this study was to evaluate biomass productivity, oil content, and oil composition of sweet basil (Ocimum basilicum L.) cvs. German and Mesten and holy basil (Ocimum sanctum L.) cv. Local grown at four locations in Mississippi. Overall, the three basil cultivars grew well; the fresh herbage and essential oil yields at three of the locations were high and comparable to basil yields reported in the literature. Essential oil content in air-dry herbage and the essential oil yields were as follows: 0.07% to 0.50% and 0.7 to 11.0 kg·ha−1 in sweet basil cv. Mesten, 0.2% to 0.5% and 1.4 to 13.0 kg·ha−1 in sweet basil cv. German, and 0.08% to 0.40% and 0.6 to 5.3 kg·ha−1 in holy basil cv. Local, respectively. The main constituent of sweet basil cultivars was (–)-linalool with other constituents being (–)-camphor, α-humulene, eucalyptol, eugenol, (–)-bornyl acetate, methyl chavicol, (–)-trans-caryophyllene, α-trans-bergamotene, and cadinol. The main constituents of holy basil were methyl chavicol, eugenol, and eucalyptol with other constituents being α-humulene, humulene-epoxide II, (–)-trans-caryophyllene, α-trans-bergamotene, and γ-cadinene. Our results suggest sweet and holy basils have a potential as new essential oil crops for Mississippi and possibly the southeastern United States and can provide oil yields and composition typical for the respective species.

The work deals with the possibility of improvement of qualitative and quantitative parameters of caraway (Carum carvi L.). The yield of the achenes is not satisfactory during last years and qualitative demands are clarify in correspondence to the market. The possibilities of this variation can be found in growing technology and in variety spectrum. The influence of weather is inconsiderable. Therefore, the experiments with three varieties were found (PROCHAN, KEPRON and REKORD). They were cultivated in cover crop and as pure growth on three sites. The yield components were evaluated in all variants: the yield of the achenes from m2, HTS (the weight of thousand seeds in g), the essential oil content in % and essential oil yield in kg.ha–1. On the basis of the results from the experiments we can make following conclusions. The highest yield was recorded in Šumperk site with cover crop. The varieties did not affect the yield. HTS was different on the sites, the highest HTS had the achenes from Telč. The differences were determined between vegetative periods. Also the essential oil content, similarly as the HTS, was influenced by the vegetative period and by the site. The essential oil yield corresponded with the essential oil content and with the yield of the achenes. The vegetative period almost always affected yield and the quality of caraway fundamentally. There were no differences among the varieties for all studied traits.

Herb Yield

One of the major factors limiting the production of medicinal plants in arid and semi-arid areas is water deficit or drought stress. One-third of the land in the world is arid and semi-arid and is inhabited by nearly 4 × 108 people. Ocimum basilicum (sweet basil) is a valuable medicinal plant that is sensitive to water deficit, and water shortage negatively affects sweet basil yield and quality. Water availability in the root zone of basil could ameliorate the negative effects of water shortage. To the best of our knowledge, although the effects of hydrophilic polymers (HPs) have been studied in different agricultural crops, the effects of HP application in medicinal plants have not been previously investigated. This investigation was conducted to explore the effects on water use efficiency when using Stockosorb® (STS) and psyllium seed mucilage (PSM) as hydrophilic polymers (HPs) and the effects of these HPs on essential oil quality, quantity, and yield. The research was set up in a factorial experiment on the basis of completely randomized block design with three replications. We used two HPs, STS (industrial) and PSM (herbal), with two methods of application (mixed with soil, mixed with soil + root) at four concentrations (0%, 0.1%, 0.2%, and 0.3% (w/w)). Results showed that the STS and PSM significantly increased the dry herb yield (both shoot and root) in comparison to the control, and the improving effect was higher when these HPs were mixed with soil + root. The highest dry herb yield (6.74 and 3.68 g/plant for shoot and root, respectively) was detected in the PSM at 0.1% mixed with soil + root. There was not any significant difference in dry herb yield among PSM (0.1%), PSM (0.2%), and STS (0.2%) when mixed with soil + root. Soil application of PSM and soil + root application of STS at a concentration of 0.3% increased the Essential Oil (EO) content almost three-fold in comparison to the control (0.5% and 0.52% to 0.18% v/w, respectively). The maximum essential oil yield was recorded in plants treated with STS (0.2% in) or PSM (0.1%) by soil + root application (0.21 and 0.19 mL/plant, respectively). PSM at concentrations of 0.1% and 0.2% (mixed with soil + root) showed the highest water use efficiency (1.91 and 1.82 g dry weight (DW)/L H2O, respectively). STS mixed with soil also significantly improved water use efficiency (WUE) in comparison to the control. The application of these HPs improved the quality of sweet basil essential oil by increasing the linalool and decreasing the eugenol, epi-α-cadinol, and trans-α-bergamotene content.
