“…Therefore it makes improved dry matter yield and yield compounds(Voko et al 2022;Greco et al 2021). Our outcomes are also similar to the work ofMumivand et al (2023), they reported that application of biochar increased peppermint (Mentha × piperita L.) yield and yield compounds and also photosynthesis pigments (chlorophylls and carotenoid).…”

“…It became delayed the aging of leaves and their fall, thereby improving the leaf/stem ratio. Considering that leaves and owers have the highest amount of essential oil in basil, therefore, increasing the ratio of leaves to stems can play an effective role in increasing the quality and quantity of essential oil produced (Shushupti et al 2022;Mumivand et al 2023).…”

“…The essential oil yield increased by increasing the use of vermicompost and also application of biochar, due to the increase in the leaf/stem ratio. Because vermicompost and biochar prepare nitrogen for basil and increased leaf area (Mumivand et al 2023). Also, light is one of the most important factors for photosynthesis, which has a great effect on increasing the percentage of essential oil.…”

Intercropping systems as an eco-friendly strategy, meliorates the quality of the agro-ecosystem. On the other hand, usage of soil amendments was environmental friendly technology to improve sustainability of soil resources and production plants. This two-year (2018–2019) study target to distinguish the quality and quantity of sweet basil in intercropping system with forage turnip with usage of vermicompost and biochar as a soil amendments. The treatments in the main plots were: A1: 90% forage turnip + 10% basil; A2: 80% forage turnip + 20% basil; A3: 70% forage turnip + 30% basil, in main plots; also two vermicompost levels (15 ton ha− 1, 18.5 ton ha− 1) and two biochar levels (control, 5 ton ha− 1) were placed in subplots. Thus, intercropping of basil and forage turnip at level of 70% forage turnip + 30% basil with biochar and vermicompost at 18.5 ton ha− 1 was the best performance compared to another treatments. That treatment promoted chlorophyll (a + b) 65.32%, carotenoid 67.47%, soluble sugars 77.35%, relative water content 33.13%, dry matter yield 62.54%, essential oil 63.15%, essential oil yield 191.76% and reduced membrane stability index 150.95%, compared to 90% forage turnip + 10% basil and vermicompost at 15 ton ha− 1 (without biochar). Thus, it can be suggested to farmers as an ecological friendly methods to improve basil yield and yield compounds.

“…Plant cells are usually preserved against the adverse in uences of ROS by a concerted action of both enzymatic and non-enzymatic antioxidant constituents. The antioxidants compounds act synergistically to scavenge increased level of ROS and mitigate stress (Mumivand et al, 2023). Previous studies reported that UV-B promotes the activities of antioxidant compounds, such as α-tocopherol, avonoids, carotenoids and phenolics, which play important roles as defenses against ROS (Klem et al, 2012;Müller et al, 2013;Müller et al, 2015).…”

Background Different wavelengths of solar radiation incident on earth [herein: Photosynthetically Active Radiation )PAR(,Ultra Violet-A )UV-A( and Ultra Violet-B (UV-B)] and their spectral balance not only have an impact on plants′ growth, morphology and physiology, but also have been shown to be important for the quality and quantity of secondary metabolites produced by plants. Material and Methods In this outdoor study we addressed the effects of PAR intensity and UV on the growth, yield, antioxidative, phenolic, flavonoids and essential oil production of Pelargonium graveolens L’Hér. The experiment was performed as split plots in a randomized complete block design with three replications. During the growth, two PAR intensities (ambient PAR and reduced PAR) and four UV treatments (ambient UV, enhanced UV-A, enhanced UV-B and enhanced UVA + B) were applied. Results High PAR intensity declined the length and width of leaf, the height of plant and fresh weight of aerial part, but increased dry weight of aerial part. Enhanced UV-B irradiation was associated with reduced plant height, leaf expansion and fresh and dry weight of aerial part. Interestingly, negative influence of enhanced UV-B radiation on morphology and growth of plant was largely alleviated by high PAR intensity. The amount of total phenols and flavonoids, antioxidant activity and essential oil production of P. graveolens strongly increased with both enhanced UV-B irradiation and high PAR. On the contrary, UV-A radiation did not significantly influence total phenols, flavonoids, antioxidant activity and essential oil. Moreover, the combination of high PAR intensity and enhanced UV-B led to further increases in total flavonoid content and the antioxidant capacity. Both high PAR intensity and enhanced UV-B increased the percentage of geraniol in essential oil, leading to a slight reduction of C/G ratio. Conclusions Considering that the lower C/G ratio is the most important indicator of the high economic value of rose geranium essential oil, reducing C/G ratio under enhanced UV-B radiation and/or high PAR is likely to be favorable. Overall, we conclude that PAR and UV-B irradiation, as two important environmental factors, have positive effects on the quality and quantity of rose geranium secondary metabolites.

“…Mg and TK noticeably increased in T 2 , T 3 , and T 4 (Figure 4f,g). In the case of Mg, this was due to the disintegration of chlorophyll, a predominant molecule in GW whose structure is made up of a porphyrin ring containing Mg. As the protective lignocellulosic layer decomposes, chlorophyll is accelerated, and Mg increases in the medium [67]. On the other hand, the TK increase could be associated with the mineralization of the hemicellulose in the plantain peels from the FW [60].…”

Evaluation of Biochar as an Additive in the Co-Composting of Green Waste and Food Waste

Green waste (GW) represents 11% of municipal solid waste. Managing this waste is challenging due to its physicochemical variability, low density, and presence of hard-to-degrade lignocellulosic compounds. Composting is an alternative for GW transformation and valorization. However, due to the substrate characteristics, processing times are long, and the end product typically does not meet quality standards. Incorporating additives and co-substrates are operational strategies that contribute to overcoming these challenges. An essential step is the determination of a mixture’s composition that ensures synergistic effects on the process and end-product quality. This research assessed the effect of adding biochar (Bch) in the co-composting of GW and food waste (FW). A previously studied co-composting mixture (M) of GW, raw and processed FW, sawdust (Sd), and phosphoric rock (Pr) with four treatments by duplicate were assessed at the pilot scale: T1: 100% GW, T2: M1, T3: M2 + 2% Bch, y T4: M3 + 5% Bch. The results show that Bch treatments maintained the range of thermophilic temperatures for longer than the other two treatments (between four and five additional days), showing greater biological activity and better end-product hygienization. Likewise, in the Bch treatments, the hemicellulose and cellulose degradation improved compared to treatments without Bch by 33.9% and 23.3%, respectively, and nitrogen losses were reduced by up to 70%. Regarding the end product, adding a 2% dose of Bch allowed the highest fertility index compared to the other three treatments, showing its potential for agricultural use. This work demonstrates that adding biochar to FW and GW co-composting improves organic matter degradation rates, lignocellulosic degradation, and end-product quality.
