Abstract：
The overuse of chemical fertilizers degrades the soil ecosystem and restricts the natural development of plants. Various byproducts are produced throughout the production and consumption of coffee within the coffee industry, and they are significant in terms of environmental waste. Spent coffee grounds (SCGs) contains various bioactive compounds that have demonstrated potential applications in various fields. These compounds can enhance soil quality by improving its physicochemical properties and biological fertility, ultimately leading to improved plant growth and reducing food waste and contamination at the same time. This current study examined the impact of chemical fertilizer, vermicompost, SCGs with percentage fertilizer (SCGPF), and SCGs on the top dressing fertilizer (SCGTDF) on red radish (Raphanus sativus) growth and soil quality. This greenhouse experiment tested various concentrations of SCGPF (5%, 10%, 25%, and 50%) and different doses of SCGTDF (0.5 g, 1 g, and 2.5 g). The results showed that the 0.5 g SCGTDF treatment yielded the highest mean plant length (18.47 cm) and fresh weight (27.54 g), while the vermicompost at a 50% concentration produced the highest mean leaf surface area (58.32 cm2). These findings suggest the potential of SCGs as a sustainable fertilizer alternative, contributing to improved plant growth and soil quality, thus supporting sustainable agricultural practices and a circular economy.
摘要：
化肥的过度使用使土壤生态系统退化，限制了植物的自然发育。在咖啡行业的整个咖啡生产和消费过程中会产生各种副产品，它们在环境废物方面意义重大。废咖啡渣（SCG）含有各种生物活性化合物，已证明在各个领域的潜在应用。这些化合物可以通过改善土壤理化性质和生物肥力来提高土壤质量，最终导致改善植物生长，同时减少食物浪费和污染。目前的研究检查了化肥的影响，Vermicompost,含百分比肥料的SCG（SCGPF），和SCG上的追肥（SCGTDF）对红萝卜（Raphanussativus）的生长和土壤质量的影响。这个温室实验测试了各种浓度的SCGPF(5%，10%,25%,和50％）和不同剂量的SCGTDF（0.5g，1g,和2.5g)。结果表明，0.5gSCGTDF处理的平均株长(18.47cm)和鲜重(27.54g)最高，而浓度为50％的蠕虫产生最高的平均叶片表面积（58.32cm2）。这些发现表明SCGs作为可持续肥料替代品的潜力，有助于改善植物生长和土壤质量，从而支持可持续农业实践和循环经济。
