“…Accordingly, the highest yield was obtained at the highest nitrate concentration (i.e., the 80:20). Moreover, the overall yield was higher at the first cut [ 32 , 33 ]. Nonetheless, it is interesting that yield did not significantly decrease with the 60:40 ratio.…”

Sweet basil (Ocimum basilicum L.) is a leafy green with a short-production cycle that is emerging as a model species among aromatic plants. Modulating the mineral composition of the nutrient solution has proved to be a valuable tool to uncover the mechanisms and responses that higher plants adopt in relation to the availability of mineral nutrients. The aim of this work was to examine the effects on basil of four isosmotic nutrient solutions with different nitrate to chloride ratios. These two anions share uptake and transport mechanisms in plants and are often considered antagonist. To this goal, we analyzed morpho-anatomical and physiological parameters as well as quality-related traits, such as the antioxidant capacity, the leaf color, the mineral composition, and the aromatic profile in relation to the nutrient ratios. Moreover, using a full factorial design, we analyzed leaves in two consecutive harvests. The data indicated a broad, multifaceted plant response to the different nutritional ratios, with almost all the recorded parameters involved. Overall, the effects on basil can be explained by considering an interdependent combination of the nitrate and chloride roles in plant nutrition and physiology. Our work revealed the extent of the modification that can be achieved in basil through the modification of the nutrient solution. It also provided indications for more nutrient efficient growing conditions, because a moderate increase in chloride limits the expected negative impact of a sub-optimal nitrate fertilization.

“…Studies carried out also on aromatic plants indicated that multiple harvests could significantly affect various traits [18][19][20][21][22] but very little is known on the metabolomics changes associated with those differences. In addition, not much is known on the effects of the cut in basil in intensive production systems [23,24], especially from the agronomic point of view [10]. In this work, we studied the difference in agronomic, physiological, and quality-related traits of basil harvested in two consecutive cuts.…”

Sweet basil (Ocimum basilicum L.) is an aromatic, tender leafy green cultivated for the fresh market and industrial processing. Like many other leafy vegetables, this species can be harvested more than once to increase productivity. Although the cut-and-come-again (CC) harvest strategy is widespread in basil, not much is known about the effect of the cut. In this work, we examined differences in biomass, physiology, nutrient use efficiency and antioxidant capacity of basil leaves from two successive harvests. Moreover, we also performed an untargeted metabolomics analysis to reveal variations in the leaf metabolite profile. The data indicated that the cut affected many of the parameters under investigation, including a modest reduction of yield (−20%), of nitrogen use efficiency (−21%) and of some quality attributes such as the antioxidant capacity (−16%) and the nitrate content in leaves (+48%). Moreover, leaves of successive cuts displayed a significant variation of the profile of bioactive compounds, characterized by an overall decrease of phenylpropanoids and an increase in terpenoids. Our data revealed the impact of CC harvesting strategy in basil, and that this strategy offers the possibility to yield leaves with different metabolomics profiles and quality attributes.

“…Basil (Ocimum basilicum L.) is an important species of cultivated aromatic and medicinal plants belonging to the Lamiaceae (mint family). This family Lamiaceae includes about 3,200 species of annuals and nonwoody perennials which are widely distributed almost all over the temperate and tropical regions of the world [1][2][3].…”

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 (p < 0.01) interaction effect of genotype with plant spacing for all parameters tested. The maximum essential oil yield (7.88 kg ha−1) was obtained from genotype BO-5 at 30 cm spacing, whilst the least (2.68 kg ha−1) was recorded from BO-1 at 40 cm spacing. The maximum oil content (101 mL g−1) 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.
