Abstract:The aim of this research was to determine the effect of three organic manures (vermicompost, simple compost, compost with gypsum) with four different levels, as sources of fertilization, and mixed with river sand, this was used as an inert material, on the phenolic content, antioxidant capacity and total soluble solids of bell peppers (Capsicum annuum L.). The 12 mixtures formulated, with eight replications, were distributed in a completely randomized design. Data were statistically analyzed by analysis of var… Show more

Chili peppers are used as food and contain food nutrients such as vitamins A and C, fibre, folic acid and potassium for proper human growth and development. In addition, they are used by industries for manufacturing alcoholic, culinary and pharmaceutical products however they are perishable and undergo physico - chemical changes to cause postharvest loss of chili peppers. Therefore, the main objective of the study was to investigate the effect of varieties, solar drying and zeer pot refrigeration lining media on physico – chemical characteristics of chili peppers. A 2 x 3 x 3 factorial experimental design in Randomized Complete Block Design (RCBD) was used to collect data for laboratory analyses. The study found – out that, varieties of chili peppers had significant effect (p < 0.05) on physico – chemical characteristics of chili peppers with red cayenne significantly recorded the best pericarp thickness (0.21mm), porosity (72.3%) total soluble solids (2.42%) and pH (5.38) but titratable acidity (0.56%) of chili pepper fruits was significantly (p < 0.05) higher in scotch bonnet. Also, on effect of solar drying on physico – chemical characteristics of chili pepper fruits, there were significantly (p < 0.05) better thickness of pericarp (0.23mm), total soluble solids (2.47%), titratable acidity (0.62%) and pH (4.64) shown in unblanched solar dried chili pepper fruits while the best porosity (71.19%) was noted in controlled chili pepper fruits. Again, on effect of lining media of zeer pot refrigeration on physico – chemical characteristics of chili pepper fruits, thickness of pericarp (0.22mm) was significantly (p < 0.05) higher in wood shavings used as zeer pot refrigeration lining media but total soluble solids (2.03%) and porosity (69.27%) were best indicated in styrofoam used as zeer pot refrigeration lining media. Titratable acidity (0.54%) and pH (5.00) were better shown in sand used as lining media of zeer pot refrigeration.

“…AD digestate has been previously been utilized as an organic fertilizer on farms (Mostafazadeh-Fard et al ., 2019). Our observations are supported by studies that show organic fertilizer regiments producing more nutritious vegetables when compared with conventional fertilizer systems (Bimova and Pokluda, 2009; Raigón et al ., 2010; Aminifard et al ., 2013; Ibrahim et al ., 2013; Moreno-Reséndez et al ., 2016) for certain test species and experimental conditions.

Biogas digesters convert waste matter into a natural gas-like fuel and a nutrient-rich digestate by-product. This digestate has the potential to be used as a soil amendment to benefit crop production with or without biochar, a purported nutrient sponge. In a greenhouse study of several crop species, the effects of digestate fertilization on crop growth, photosynthetic efficiency, vegetable production and chemical nutrient levels were tested. Results indicate that increasing potency of the applied digestate fosters higher growth and fruit production rates of several studied plants but to a lesser degree than a conventional fertilizer. More potent digestate application increases antioxidant capacity, total phenolics content and ascorbic acid levels in kale compared to the control chemical fertilizer test groups but has confounding results on legume nutrient levels. Additionally, the combined application of biochar and biogas digestate added to compost and used as potting media positively impacts crop germination. This work has relevance to agrarian communities that could benefit from recycling livestock and food waste into fuel and a renewable fertilizer.
“…It Is also discovered that the formation of secondary metabolites that are antioxidants derived from phenolic and flavonoid groups is affected by fertilization. The 20 t/ha dose can increase metabolite compounds such as phenolic content and secondary antioxidant capacity in bell peppers (Moreno-Reséndez et al, 2016).…”
<p><span lang="IN">The production of 'Ratuni UNPAD' cayenne pepper can be increased using organic chicken manure.

The 30 t/ha shows the highest value for the number of leaves and productive branches, while 20 tons dose/ha influences flavonoids, phenolics, and total carotenoids. The ethephon concentration of 1500 ppm significantly affects the flower initiation, fruit length, diameter, capsaicin, and dihydrocapsaicin.</span></p>
