Special Issue Information

Dear Colleagues,

In recent years, agronomic biofortification has gained recognition in agriculture and nutrition as a prominent approach to combat global malnutrition by enhancing the nutrient content of staple crops. This strategy involves the implementation of agronomic practices aimed at increasing the concentration of essential minerals and vitamins in crops, thereby improving human health. While the concept of biofortification originated from traditional breeding programs focused on developing nutrient-rich crop varieties, agronomic biofortification takes a complementary approach by addressing external factors that influence nutrient uptake and accumulation in plants. By integrating knowledge from plant physiology and plant mineral nutrition, it aims to optimize both crop production and nutrient enrichment simultaneously. The objective of this Special Issue is to explore recent advancements and future prospects in agronomic biofortification. It provides a platform for researchers, agronomists, nutritionists, and policymakers to share state-of-the-art research, insights, and perspectives in this rapidly evolving field. The Special Issue encompasses studies on crop-specific biofortification approaches, innovative soil management techniques, the bioavailability of biofortified foods, and the evaluation of agronomic practices for large-scale implementation. It welcomes a variety of article types, including original research papers, opinion pieces, and comprehensive reviews. In summary, this Special Issue on Agronomic Biofortification of Crops serves as a catalyst for knowledge exchange and collaboration among experts to advance the development and implementation of effective agronomic strategies for biofortification. All types of articles, such as original research, opinions, and reviews are welcome.

Cassava (Manihot esculenta Crantz) is a crucial staple food in South America, providing starchy storage roots that contribute to the sustenance of millions. To address deficiencies in iron (Fe), zinc (Zn), and selenium (Se), a global initiative is underway to identify plant species and genotypes that naturally accumulate these nutrients for human consumption, such as cassava. In this way, this study aims to identify potential cassava genotypes for biofortification in Fe, Zn, and Se, while also improving the overall cassava yield. We evaluated the accumulation potential of Fe, Zn, and Se in 20 South American cassava genotypes under traditional growing conditions, concurrently examining their photosynthetic and growth characteristics. Cassava roots exhibited Zn content ranging from 3.20 to 8.56 mg kg−1, Fe content from 2.20 to 10.73 mg kg−1, and Se content from 1.20 to 9.43 µg kg−1 (expressed on a dry basis). Genotypes MS018, DG014, and DG839 emerged as promising candidates for biofortification programs, displaying elevated levels of Fe, Zn, and Se, coupled with superior photosynthetic capacity. These genotypes, recommended for biofortification programs, also demonstrated increased yield potential. The findings from this study contribute to the development of cassava genotypes with enhanced agronomic biofortification and elevated yield potential. Full article
