It was introduced to Europe in the 16th century and subsequently reached Iran in the 17th century. However, the apparent disappearance of potato cultivation across much of Iran during the 18th century, followed by its reintroduction in the 19th century and subsequent promotion by the state, presents a puzzling historical trajectory. This puzzle can be better understood through a careful examination of historical accounts alongside cultural, economic, linguistic, and social evidence found in travelogues, diaries, cookbooks, accounting records, and official documents. As a result, four major routes of introduction of potato cultivation into Iran were identified and discussed in detail, as follows: (A) Introduction by European merchants or diplomats, including Portuguese, Dutch, French, or English actors, via southern Iran in the 17th century; (B) Introduction via the Indian subcontinent by Indian or Iranian merchants and scholars in the 17th century; (C) Introduction through northwestern Iran by Russian merchants or diplomats during the 18th and 19th centuries; and (D) Introduction via central Iran by British agents in the 19th century. Considering the fact that the multiple and asynchronous waves of potato introduction to Iran take almost two-hundred years to gain the acceptance of the plant by the Iranian population, it suggests that the success or failure of introducing, cultivating and consuming a crop such as potato depends not only on its nutritional and agronomic merits but also on a complex interplay of historical, economic, and cultural factors, some of which are their accessibility, affordability, cultural acceptability, political intentionality of their introduction and their culinary integrability.</p></div>","PeriodicalId":7596,"journal":{"name":"American Journal of Potato Research","volume":"103 5","pages":"549 - 563"},"PeriodicalIF":1.5,"publicationDate":"2026-09-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149099163","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A two-year field study was conducted on two different sites to evaluate the interactive effects of five N fertilization rates (0-314 kg N ha<sup>-1</sup>) and a microbial biostimulant on potato yield, tuber quality, soil N dynamics, and microbial biomass.
