Abstract: Potato (Solanum tuberosum L.) is a nutrient-intensive crop for which optimised fertility management is critical to sustaining yields, profitability and environmental performance. This systematic academic review evaluated global research trends in fertility management for potato cultivation from 2000 to 2024, with particular emphasis on the evolution of intervention types, geographic and thematic coverage, outcome domains and methodological quality. A structured search of major bibliographic databases and grey literature identified 82 eligible studies encompassing integrated nutrient management (INM), site-specific nutrient management (SSNM) and QUEFTS-based approaches, mineral fertiliser benchmarking, organic and biofertilizer regimes, and cover-crop or green-manure systems. Descriptive statistics, cross-tabulation and simple inferential tests were used to characterise research patterns and synthesise agronomic, economic, quality, soil health and environmental responses. Publication output on potato fertility management increased sharply after 2015, with South Asia and a few high-income regions dominating the evidence base. INM and SSNM consistently produced higher tuber yields and greater nutrient-use efficiency than farmer practice or mineral-only strategies, and generally improved net returns. Organic, biofertilizer and cover-crop interventions contributed positively to soil organic matter and nutrient status but often yielded smaller short-term gains in productivity and profitability. Outcome reporting was strongly skewed toward agronomic variables, with fewer studies including economic, tuber quality, soil biological and environmental indicators. Methodological limitations included the prevalence of single-season trials, incomplete statistical reporting and limited integration of multiple outcome domains. The review highlights the need for more holistic, multi-location research that combines INM and SSNM concepts, incorporates standardised quality and sustainability metrics, and extends systematic evidence generation to under-represented potato-growing regions, thereby supporting more resilient and environmentally responsible fertility management strategies.
