Purslane (\n                    <jats:italic>Portulaca oleracea<\/jats:italic>\n                    L.) is a promising candidate owing to its exceptional nutritional profile and adaptability to harsh agroecological conditions. This review provides a comprehensive and critical synthesis of existing literature on the agronomic management, nutritional composition, and functional food potential of purslane, with particular emphasis on its omega-3 fatty acid content and the role of nitrogen and mineral nutrition. The review reveals that purslane is a rich source of alpha-linolenic acid (ALA), vitamins (C and E), carotenoids, minerals, and diverse bioactive compounds with antioxidant and anti-inflammatory properties. However, its nutritional quality is highly variable and influenced by genotype, environmental conditions, cultivation systems, and nutrient management strategies. Nitrogen plays a dual role of enhancing biomass production while exerting complex, compound-specific effects on nutrient density, often leading to trade-offs between yield and quality. The novelty of this study lies in its integrated, multi-dimensional perspective that links agronomy, plant physiology, and nutritional science, moving beyond fragmented analyses in existing literature. It highlights the importance of genotype-by-environment interactions and introduces the concept of \u201cnutritional efficiency\u201d as a more appropriate framework than yield-focused optimization. This study contributes to knowledge by identifying critical gaps and proposing a systems-based approach for optimizing purslane as a sustainable, plant-based source of omega-3 fatty acids and functional nutrients, particularly in resource-constrained and climate-vulnerable regions.\n                  <\/jats:p>","DOI":"10.3389\/fpls.2026.1898609","type":"journal-article","created":{"date-parts":[[2026,7,29]],"date-time":"2026-07-29T15:26:22Z","timestamp":1785338782000},"update-policy":"https:\/\/doi.org\/10.3389\/crossmark-policy","source":"Crossref","is-referenced-by-count":1,"title":["Agronomic management enhances nutritional quality and functional food potential of purslane (Portulaca oleracea L.): a review"],"prefix":"10.3389","volume":"17","author":[{"given":"Peter A.Y.","family":"Ampim","sequence":"first","affiliation":[{"name":"College of Agriculture, Food, and Natural Resources (CAFNR) Research, CAFNR, Prairie View A&M University","place":["Prairie View, TX, United States"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Eniola A.","family":"Faluyi","sequence":"additional","affiliation":[{"name":"College of Agriculture, Food, and Natural Resources (CAFNR) Research, CAFNR, Prairie View A&M University","place":["Prairie View, TX, United States"]},{"name":"School of Public and Allied Health, Prairie View A&M University","place":["Prairie View, TX, United States"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Monsuru A.","family":"Salisu","sequence":"additional","affiliation":[{"name":"College of Agriculture, Food, and Natural Resources (CAFNR) Research, CAFNR, Prairie View A&M University","place":["Prairie View, TX, United States"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Andrea","family":"McDonald","sequence":"additional","affiliation":[{"name":"School of Public and Allied Health, Prairie View A&M University","place":["Prairie View, TX, United States"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Angela","family":"Branch-Vital","sequence":"additional","affiliation":[{"name":"School of Public and Allied Health, Prairie View A&M University","place":["Prairie View, TX, United States"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Janet","family":"Antwi","sequence":"additional","affiliation":[{"name":"College of Agriculture, Food, and Natural Resources (CAFNR) Research, CAFNR, Prairie View A&M University","place":["Prairie View, TX, United States"]}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1965","published-online":{"date-parts":[[2026,7,29]]},"reference":[{"key":"B1","doi-asserted-by":"publisher","first-page":"5529","DOI":"10.1002\/ptr.7997","article-title":"The effects of purslane (Portulaca oleracea) on glycemic indices: A GRADE\u2010assessed systematic review and meta\u2010analysis of randomized controlled trials","volume":"37","author":"Abbasi","year":"2023","journal-title":"Phytother.
