“…DPPH, ABTS, and FRAP activity significantly decreased under 150 and 250 µmol m −2 s −1 PPFD with fertilization, meanwhile without additional lighting, the opposite effect was observed (Figure 3). The effects of fertilization on anthocyanins in basil are contradictory-some studies show no effect of fertilization on anthocyanins [31], while others show a significant increase in anthocyanins regarding the use of fertilizers [33]. According to our results, in low-light conditions (up to 150 µmol m −2 s −1 PPFD), fertilization significantly increased the concentration of anthocyanins in basils leaves, while under 250 µmol m −2 s −1 PPFD, fertilized basil was found to have a significantly lower concentration of anthocyanins than that in unfertilized basil (Figure 4).…”

Light and nutrients are among the most important factors for sustained plant production in agriculture. As one of the goals of the European Green Deal strategy is to reduce energy consumption, greenhouse growers focus on high-value crop cultivation with less-energy-demanding growing systems. This study aimed to evaluate the effect of fertilization at different light intensities on the growth of lettuce and basil and the activity of the antioxidant system. Sweet basil (Ocimum basilicum, ‘Opal’) and lettuce (Lactuca sativa, ‘Nikolaj’) were grown in a greenhouse supplementing natural light (~80 µmol m−2 s−1) with lighting at two photon flux densities (150 and 250 µmol m−2 s−1), 16 h photoperiod, and 20/16 °C day/night temperature in May (Lithuania, 55°60′ N, 23°48′ E). In each light regime treatment, half of the plants were grown without additional fertilization; the other half were fertilized twice a week with a complex fertilizer (NPK 3-1-3). The results showed that the antioxidant activity of basil was most affected by 150 µmol m−2 s−1 PPFD lighting and the absence of fertilization. Altered antioxidant activity in lettuce in the presence of 250 µmol m−2 s−1 PPFD additional light intensity and fertilization resulted in higher morphological parameters.

“…In contrast, SPAD values of basil from aquaponics with HFS and standard substrates were not signi cantly different and higher compared with those taken from supermarkets, except sample MIII (Netto ApS & Co. KG). SPAD levels in the aquaponics and the market samples were lower than reported for basil irrigated with organic fertiliser (chicken manure) of 35.18%, and the SPAD of the control group plants were closer to basil fertilised with spores of mycorrhizal fungi and bacteria of 40.27% [53]. Lower leaf chlorophyll content was found in basil cultivated in aquaponics with cray sh (Procambarus spp.…”

A major challenge in agriculture, horticulture and aquaponics practices is the reduction of mineral fertilisers and peat to reduce CO2 emissions and increase sustainability. This study used a three-phase-natural fertiliser, the Humicacid Fiber-Substrate (HFS), made from natural regenerative organic and mineral-fractions (Humus-Mineral-Complex), to reduce the peat content in plant pots for aquaponics farming. Basil (Ocimum basilicum) growth was compared with i) 100% standard media substrate ("Einheitserde", white peat 80%, clay 20%), and ii) 85% "Einheitserde" and 15% of HFS under irrigation with aquaculture process waters from an extensive and intensive production of African catfish (Clarias gariepinus) under coupled aquaponic conditions. The substitution with 15% HFS and use of intensive fish water resulted in comparable plant growth to a fertiliser solution as control, and in higher leaf width and leaf green weight and lower root dry weight compared with the standard media substrate "Einheitserde". Basil leaf chlorophyll content from the aquaponics was higher compared with local market plants. This suggests the possible substitution of the peat substrate "Einheitserde" with at least 15% HFS to reduce the natural peat fraction. Further studies on crop-specific substrates are needed to reduce peat in aquaponics farming plant cultivation.

Periodic removal of sediment from aquaculture ponds is practiced to maintain their productivity and animal welfare. The recovery of sediment as a plant fertilizer could alleviate the costs of sediment removal. The objective of this study was to test the effects of a dried sediment, extracted from an aquaculture pond used for common carp cultivation, on the growth and physiology of potted wheat grass and the quality of the juice obtained from wheat grass. The results showed that sediment application did not produce significant morphological changes, although the values for plant height (16.94–19.22 cm), leaf area (19.67–139.21 mm2), and biomass (3.39–4.26 g/plant) were higher in sediment-grown plants. However, at a physiological level, the effect was negative, decreasing photosynthesis (0.82–1.66 μmol CO2 m2s−1), fluorescence ΦPSII (0.737–0.782), and chlorophyll content (1.40–1.83 CCI). The juice yield was reduced in the sediment treatments (46–58 g/100 g), while the quality was improved by increasing the content of phenols (2.55–3.39 µg/mL gallic acid equivalent), flavonoids (1.41–1.85 µg/mL quercetin equivalent), and antioxidant activity (47.99–62.7% inhibition of ;2,2-diphenyl-1-picrylhydrazyl). The positive results obtained in this study can be attributed to the moderate nutrient content of the sediment and a negligible concentration of heavy metals.
