Special Issue Information

Dear Colleagues,

Rapid developments in technology have enhanced globalization and people are more concerned about one another. Therefore, sensitivity to global food security is increasing day by day. However, in recent times many global drivers have diverted the attention of world communities fighting against hunger and food insecurity. It is challenging to achieve the targets of food security, especially in developing countries. Post COVID-19 challenges also enhance the threats to food security of poor resource countries. Besides global hunger “hidden hunger” has come up with the great potential to threaten food security, also affecting the human immune system. Hidden hunger (micronutrient malnutrition) is affecting more than half of the world's population and is a reason for a wide range of diseases. Pre-school-going children, young girls, and women are the main victims of micronutrient malnutrition. Changing living styles and reducing the nutritious value of staple foods are the main reason for this alarming issue. Crop biofortification has been considered an effective tool to combat micronutrient malnutrition for decades, especially in developing countries. Low bioavailability of essential microelements in edible parts of food crops is also affecting well-off global populations. Although efforts are being made worldwide and many successes have also been reported; however, is still a lot to do because the contribution of biofortification is still very limited and needs an immediate extension. 

The purpose of this Special Issues is to highlight the recent research on biofortification, policy development to use the biofortification as a tool to combat malnutrition and to come up with further suggestions to expedite the biofortification eliminating all relevant concerns. Furthermore, collecting a set of articles from different parts of world will also provide the base for further research work on this issue.

Iron (Fe) deficiency in humans, particularly in pregnant women and children, is caused by inadequate dietary Fe intake and is a global nutritional problem. Foliar fertilization is a cost-effective agronomic approach to increase Fe bioavailability in the human diet. We evaluated the effects of different Fe formulations (Fe-citrate, Fe-EDTA, FePO4, nano-Fe oxide, and humic acid (HA) with and without Fe) on growth, yield, and Fe accumulation in the edible parts of rice, soybean, and lettuce crops. Rice and soybean received multiple sprays at different growth stages, i.e., tillering, anthesis, and grain filling in rice as well as flowering and pod filling in soybean, while lettuce received a single foliar spray. In rice and soybean, the seed Fe accumulation increased proportionally as the number of foliar sprays increased; however, the grain yield did not show this relationship. Among Fe treatments, HA+Fe was identified as the best treatment in terms of improving overall plant growth, yield, and Fe accumulation in the edible parts of all three crops. We found a significant positive correlation between the shoot/stover Fe content and the grain Fe content, but HA+Fe showed an opposite trend, i.e., minimal Fe retention in shoots/stovers and maximal increases in the seed Fe contents in both crops, suggesting better Fe mobilization efficiency from shoots to developing seeds. We strongly recommend that HA with Fe can be used as a foliar Fe fertilizer to improve the growth, yield, and Fe status in different crops. Full article
