Phytochemicals and antioxidant properties of red sweet pepper cv grown in soil amended with different organic fertilizers were compared with that grown in unamended soil. Organic fertilizers are an environmentally friendly alternative to recovery infertile soils that resulted from the intensified agricultural practices in red production. The aim was to discriminate the effects of organic fertilizers one from each other on the quality of red to find out the better sustainable fertilization practice for its cultivation. Results showed that compost from vegetable residues (CV) enhanced the synthesis of total phenols, flavonoids, ascorbic acid, vitamin E, carotenoids, anthocyanins, as well as carbohydrates, antioxidant activities, and aroma profiling, compared to horse manure (HD), compost from olive pomace (CO), and control (CTR). The results indicated a specificity between the quality of red and compost composition, highlighting that vegetable residues increased the synthesis of secondary metabolites, enhancing sustainably, the nutraceutical, sensorial, and economic value of red . The fertilizer composition resulted largely responsible for the synthesis of bioactive compounds, flavor, and aroma of this fruit.
比较了在添加不同有机肥料的土壤中种植的红色甜椒品种的植物化学物质和抗氧化特性与在未改良土壤中种植的红色甜椒的相关特性。有机肥料是恢复因红色甜椒生产中集约化农业 practices 导致的贫瘠土壤的一种环境友好型替代方法。目的是区分不同有机肥料对红色甜椒品质的相互影响，以找出其种植的更好的可持续施肥方法。结果表明，与马粪（HD）、橄榄渣堆肥（CO）和对照（CTR）相比，蔬菜残渣堆肥（CV）增强了总酚、类黄酮、抗坏血酸、维生素E、类胡萝卜素、花青素以及碳水化合物的合成、抗氧化活性和香气剖析。结果表明红色甜椒品质与堆肥成分之间存在特异性，突出表明蔬菜残渣增加了次生代谢产物的合成，可持续地提高了红色甜椒的营养、感官和经济价值。肥料成分在很大程度上决定了这种果实生物活性化合物的合成、风味和香气。
