Leafy shoots of sweet basil (Ocimum basilicum Linn.) were exposed to the vapor of either dilute acetic acid (AA) or of upland rice vinegar (URV) – both solutions were diluted to contain 4% of acetic acid – for 10 min and stored at 12°C. The sweet basil exposure to AA had a 16% increase in shelf life and those exposures to URV 35% increase compare to the control. There were no significant differences in fresh weight loss during storage between the AA and URV but both had significantly lower fresh weight losses than the control. The chlorophyll content of both AA and URV were significantly higher than the control. The radical scavenging was significantly higher in the URV than in the AA and the control. The electrolyte leakage was both significantly lower in the URV than in the AA and the control. The occurrence of lipid peroxidation was similar in both the AA and URV, and both were significantly lower than in the control. These results indicate URV has potential as an effective way of raising quality and extending postharvest storage of sweet basil shoots.

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.

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.

Herb Yield

The aromatic and curative properties of basil are connected with the presence of essential oil, mainly in the leaves and flowers. Herb yield and the quality of basil oil are related to the effect of genetic, ontogenetic and environmental factors. In the studies conducted in the years 2008-2009, the effect of basil cultivar and foliar feeding upon selected flowering features was examined. In an unheated plastic tunnel, plants of Kasia, Wala, Genua Star and Opal cultivars were grown. Foliar feeding was done by the application of 0.5% urea solution or by spraying the plants with water. During harvest the characteristic features of flowering were determined, i.e. the number and length of inflorescences, as well as the number of verticils and flowers per inflorescence. A vast differentiation was demonstrated in flowering of sweet basil plants of the examined cultivars. The most inflorescences were formed by the plants of the Polish cultivar Kasia, compared to the remaining ones. The longest inflorescences with the highest number of flowers in the main inflorescence were found in 'Genua Star'. Foliar feeding of the plants with nitrogen caused a significant increase of inflorescence number, but it did not significantly affect the remaining features of basil flowering.

Storage Temperatures

Shelf life (defined by visual quality) of freshly harvested greenhouse-grown sweet basil was maintained for an average of ≈ 12 days at 15C. Chilling injury symptoms were severe at storage temperatures of 5C and below. Shelf life was found to be only 1 and 3 days at 0 and 5C, respectively. Moderate chilling injury was noted at 7.5 and 10C. Harvesting sweet basil later in the day (i.e., 1800 or 2200 hr) increased shelf life by almost 100% when harvested shoots were held at 10, 15, and 20C, compared to harvesting at 0200 or 0600 hr. However, the time of day of harvest did not alter the development of visual chilling injury symptoms or improve shelf life at 0 or 5C.
