abstract
Zero Budget Natural Farming (ZBNF) is gaining global attention as a sustainable, low-cost agricultural approach that aligns with agroecological principles. This review aims to map the global research trends, institutional collaborations, and thematic developments surrounding ZBNF through a bibliometric lens. A total of 447 publications were retrieved from the Scopus database using carefully selected keywords. After applying inclusion and exclusion criteria, 120 relevant articles were analysed using R Studio and VOS viewer to visualize patterns in scientific production, author collaboration, and keyword co-occurrence. Results indicate a sharp increase in research output from 2019 onward, with peak activity in 2024. Countries such as India, Italy, and China lead in scholarly contributions, while institutions like the University of Reading and Tamil Nadu Agricultural University show growing research engagement. Thematic clusters revolve around sustainable agriculture, soil health, farmer empowerment, and policy relevance. Despite growing interest, gaps remain in geographic representation, gender dynamics, and long-term ecological outcomes. This study underscores the importance of fostering international and interdisciplinary collaboration to strengthen the evidence base and policy integration of ZBNF. By offering a comprehensive bibliometric overview, the review contributes to the global discourse on sustainable agriculture and highlights pathways for future research
