“…botrytis), coconut cores, and fungal waste-and found that vermicomposting demonstrated superior fertilizing properties compared to traditional composting. Maharjan et al [46] and Rupani et al [47] affirm the benefits of using earthworms in converting organic waste into vermicompost, although they note that this method may not always be universally efficient or applicable.…”

The cultivation of corn holds immense importance as a foundational global grain crop, catering to human sustenance and serving as vital animal feed. Moreover, corn plays a substantial role in biofuel production. Additionally, cultivating corn can have a positive effect on crop rotation by improving soil quality and reducing erosion. In a pot trial using six distinct compost variations derived from different organic wastes as fertilizers for GS210 corn, specific indices, such as Fv/Fm (0.80, 0.80, 0.81), Fv/F0 (4.07, 3.99, 4.03), PI (4.62, 4.22, 5.21), and RC/ABS (1.71, 1.68, 2.01), exhibited the highest values. Interestingly, mineral fertilization with NPK displayed significant benefits on various growth parameters like plant height (188.9 cm), cob length (17.50 cm), grains per cob (324.0), and thousand-grain weight (MTZ) (285.2). The difference in the cob grain count between NPK mineral fertilization and the control reached 168.5 grains, which was statistically confirmed. Furthermore, the grain’s protein content notably increased with mineral fertilization (9.5) compared to the control (8.5). While organic fertilizers showed lower outcomes (9.1–9.3) than NPK mineral fertilization, they generally outperformed the control (8.5). This prompts the need for future studies to assess the effectiveness of individual organic fertilizers in combination with mineral nitrogen fertilization.

“…Several studies have focused on the recycling of organic waste to produce reusable products in agriculture. A typical example is the use of vermicomposting to improve the quality of compost and to ensure that earthworms are usable in animal production (Vodounnou et al 2016;Biswas et al 2022; Zarea & Kamir 2022; Maharjan et al 2023). Organic waste is also composted by various methods with the aim of improving the quality of compost for better yield in crop production (Alling et al 2014;Truong et al 2019;Aboyeji et al 2023; Rachid et al 2023).…”

Black soldier fly larvae (BSFLs) are used for recycling organic waste. The aim of this study was to evaluate the effects of cassava, yam and sweet potato peels on BSFL production. Four different treatments were performed in triplicate in a completely random block consisting of soy bran (TSB), cassava peel (TCP), yam peel (TYP) and sweet potato peel (TPP). A density of 1 larva/g of substrate was used with a uniform ratio of 100 mg/larva/day. Larval growth was 10 days, and growth monitoring was carried out every 2 days. The daily weight gain (DWG) ranged from 2.19 ± 0.09 g/d (TYP) to 4.53 ± 0.02 g/d (TSB). The production of these fungi ranged from 43.90 ± 1.87 g/kg of substrate (TYP) to 90.56 ± 0.54 g/kg of substrate (TSB). The degradation rate ranged from 36.00 ± 2.30% (TYP) to 65.00 ± 2.88% (TSB), and the survival rate ranged from 77.66 ± 1.45% (TYP) to 99.00 ± 0.28% (TSB). According to the Z correlation test, there was a strong correlation between the organic matter content of the substrates and the DWG (99.1%). It was also observed that phosphorus content was strongly correlated with DWG (92.9%). Regarding the nutritional quality of the larvae, the protein content varied from 33.51 ± 0.94% (TYP) to 40.64 ± 032% (TSB), and the lipid content varied from 26.24 ± 0.35% (TYP) to 30.44 ± 0.18% (TSB). We noticed generally a significant difference (p < 0.05) between the different treatments depending on the parameters. This study revealed that casava, yam and sweet potato peels can be used for BSFL production.
