“…This result can be attributed to the different plant material and the different densities that were almost double (226 and 593 plants m –2 ) compared to those tested (159 and 317 plants m –2 ) in the current study. However, the double density (D High ) in our experiment led to an increased fresh yield and dry shoot biomass for all assayed cultivars, as supported by the results reported in the reviewed literature ( Miceli et al, 2003 ; Maboko and Du Plooy, 2013 ; Mahlangu et al, 2020 ). Nonetheless, the increased fresh yield and dry biomass at the higher density is due to the higher number of plants per unit area ( Maboko and Du Plooy, 2013 ), as highlighted by the lower number of leaves and nodes per plant.…”

“…This challenge has led the scientific community and growers to focus on alternative growing methods with controlled environmental and nutrient conditions such as hydroponics ( Maggini et al, 2014 ; Salachas et al, 2015 ). These systems can guarantee higher yields, improve nutritional quality, reduce the incidence of pests and pathogens ( Pardossi et al, 2006 ; Kiferle et al, 2013 ; Maboko and Du Plooy, 2013 ; Walters and Currey, 2015 ), allow the seasonal adjustment of production, and shorten production cycle ( Hassanpouraghdam et al, 2010 ). Among hydroponic techniques, the floating raft system (FRS) is well-suited to the large-scale cultivation of relatively small medicinal and aromatic plants such as basil, due to simplicity of management and cost-effectiveness ( Miceli et al, 2003 ; Valenzano et al, 2003 ; Pardossi et al, 2006 ; Maggini et al, 2010 ).…”

“…In basil, different pre-harvest factors can be manipulated to improve yield and quality, leading to the conclusion that pre-harvest factors should be simultaneously analyzed to uncover their translational value and significant interactions in cultivation ( Chen et al, 2004 ; Raimondi et al, 2006 ; Nicoletto et al, 2013 ; Corrado et al, 2020a ). For instance, plant density plays a key role in shaping growth and development of different plant organs ( Maboko and Du Plooy, 2013 ; Morano et al, 2017 ). Likewise, in the ordinary cultivation of basil, plants are cut more than once during the crop cycle, with harvests having a cut-specific leaf quality profile ( Nicoletto et al, 2013 ; Corrado et al, 2020a ).…”

Morpho-Physiological Responses and Secondary Metabolites Modulation by Preharvest Factors of Three Hydroponically Grown Genovese Basil Cultivars

Sweet basil (Ocimum basilicum L.) is an economically important leafy vegetable especially in Mediterranean countries. In Italian gastronomy, the large elliptical leaves of the Genovese type are mostly used for the well-known pesto sauce, and almost all (>90%) professional production is for the food industry. The growing demand for fresh leaves with standardized technological and sensory characteristics has prompted basil producers to adopt advanced cultivation methods such as the floating raft system (FRS). The aim of this study was to evaluate the productive, qualitative, and physiological performance of three Genovese basil cultivars (“Aroma 2,” “Eleonora,” and “Italiano Classico”) in two successive harvests and at two densities (159 and 317 plants m–2). Caffeic, chicoric, rosmarinic, and ferulic acid were determined through the high-performance liquid chromatography (HPLC) system, whereas the extraction and quantification of the volatile organic compounds (VOCs) were performed by solid-phase microextraction (SPME) and gas chromatography coupled to a mass spectrometer (GC/MS). “Aroma 2” showed the highest fresh yield and photosynthetic rate together with the lowest nitrate content. For all the tested cultivars, the higher density, while reducing the number of leaves per plant, resulted in higher fresh and dry production per unit area, without altering the aroma profile. Successive harvests resulted in a significant increase in both the yield (37.5%) and the total phenolic acids (75.1%) and favored Eucalyptol and 1-octen-3-ol accumulation (+25.9 and +15.1%, respectively). The here presented comprehensive and multifactorial assessment of the productive and qualitative response of basil provides evidence of the positive effects (from biomass to specialized metabolites) that can be obtained from the management of the pre-harvest factors in soilless cultivation. In addition, it also highlights the role and constraints of the genetic factor in the observed response. We also discuss the implications of our work considering the impact for the food processing industry. Future research may explore the phenolic acids accumulation as a possible fortification means to extend the pesto sauce shelf life, reducing the need of added antioxidants and thermal processing.

“…The best production and quality performance combined with the efficient use of water and nutrients that characterize closed-loop soilless cultivation [ 32 ] have captured the attention of the entire agricultural sector. Among the various pre-harvesting factors, the genetic starting material and the nutrition management portray crucial factors in defining quality parameters [ 25 ].…”

Basil (Ocimum basilicum L.) is among the most widespread aromatic plants due to its versatility of use and its beneficial health properties. This aromatic plant thrives in hydroponics, which is a valid tool to improve the production and functional quality of crops, but nevertheless, it offers the possibility to de-seasonalize production. A floating raft system was adopted to test the production and quality potential during autumn season of three different genotypes of Genovese basil (Aroma 2, Eleonora and Italiano Classico) grown in three nutrient solutions with crescent electrical conductivity (EC: 1, 2 and 3 dS m−1). The aromatic and phenolic profiles were determined by GC/MS and HPLC analysis, respectively. The combination Aroma 2 and the EC 2 dS m−1 resulted in the highest production, both in terms of fresh weight and dry biomass. The 2 dS m−1 treatment determined the major phenolic content, 44%, compared to the other two EC. Italiano Classico showed a higher total polyphenolic content in addition to a different aromatic profile compared to the other cultivars, characterized by a higher percentage of Eucalyptol (+37%) and Eugenol (+107%) and a lower percentage of linalool (−44%). Correct management of the nutritional solution combined with adequate genetic material managed an improvement in the production and the obtainment of the desired aromatic and phenolic profiles.

“…oil varied because of the genotypic differences of the basil, which partially explained the results. A complementary explanation of these differences (plant spacing in the channels of hydroponic systems) may be related to the inter or intraspecific competition of plants for light, air, water and nutrients (Maboko and Du Plooy, 2013;Skrypnik et al, 2019), modifying the assimilation capacity and, therefore, the secondary metabolism in favor of biosynthesis and the accumulation of different volatile compounds (Hassanpouraghdam et al, 2010;Ciriello et al, 2020).…”

Reusing domestic wastewater is an alternative for irrigated agriculture, helping to decrease pressure on good quality water. This study aimed to evaluate the biomass production and essential oil content and composition in the basil genotypes ‘Alfavaca Basilicão’ and ‘Grecco a Palla’ with different plant spacing in hydroponic systems. Two experiments were carried out between March and May (Experiment I) and July and September of 2015 (Experiment II) in a completely randomized design with four replicates in a 2×3 factorial arrangement. In Experiment I, two hydroponic systems (Laminar Nutrient Flow Technique - NFT and Deep Nutrient Flow Technique - DFT) and three plant spacings in hydroponic channels (0.20, 0.30, and 0.40 m) were evaluated. In Experiment II in the DFT hydroponic system, two types of water (tap water and treated domestic effluents) and three nutrient solution recirculation intervals (at intervals of 2, 4, and 6 h) were evaluated. In general, the dry biomass per plant, oil content and oil yield of the two basil genotypes were not influenced by the hydroponic systems, plant spacing, or water type. In Experiment II, the increase between the recirculation intervals (4 or 6 h) negatively affected genotype ‘Grecco a Palla’. Linalool was the major constituent in the essential oil of the two basil genotypes, ranging from 47.00 to 70.10% (Experiment I) and from 59.47 to 63.64% (Experiment II) in genotype ‘Alfavaca Basilicão’; in genotype ‘Grecco a Palla’, it ranged from 10.19 to 43.03% (Experiment I) and from 19.94 to 53.37% (Experiment II).
