Abstract:
This work offers a comprehensive bibliometric review of global Indigofera research published from 2016-2025, analyzing 2,001 documents indexed in Scopus, including journal articles, review papers, book chapters, and conference proceedings. It investigates the evolution of research themes, collaboration trends, and knowledge paradigms over the decade. The study finds a noticeable shift in research focus: earlier studies emphasized ecological and agronomic issues (such as forage quality, nitrogen fixation, species diversity), while recent work highlights phytochemical profiling, antioxidant capabilities, and pharmacological prospects. Collaboration network mapping shows a globally dispersed but highly interconnected institutional dominance, with many contributors remaining fairly isolated. Factorial and cluster analyses underline the interdisciplinary nature of the field, bridging agriculture, ecology, veterinary, and biomedical sciences. Keyword co-occurrence analysis reveals a chronological evolution of topics from traditional fodder and ecological studies to more sophisticated biochemical and pharmacological research. These findings suggest Indigofera plays a dual role in sustainable agriculture and natural product discovery, offering significant implications for food security and human health, with potential applications in livestock productivity, ecological restoration, and pharmaceutical innovation. This review not only maps the current research landscape but also offers a roadmap for future studies, advocating for enhanced interdisciplinary collaboration, advanced biochemical evaluations, and translational research to fully harness Indigofera's scientific and practical potential.
