GUILLEN-ENRIQUEZ, Reyna Roxana et al. Effect of nano-biofortification with iron on yield and bioactive compounds in cucumber. Rev. Mex. Cienc. Agríc [online]. 2022, vol.13, n.spe28, pp.173-184.  Epub 13-Jan-2023. ISSN 2007-0934.  https://doi.org/10.29312/remexca.v13i28.3272.

Iron (Fe) is an indispensable micronutrient for living beings. However, and despite the fact that it is one of the most abundant metals in the earth’s crust, there is low availability for crops, causing a deficit in the diet of around two million people in the world. Nano-biofortification can mitigate this deficiency since its application in crops improves the biosynthesis of bioactive compounds and promotes their bioaccumulation. The objective of this research was to evaluate the effect of foliar application of Fe nanoparticles (Fe2O3 NPs) on the yield and biosynthesis of bioactive compounds in cucumber fruits. Four treatments were applied via foliar: 0, 50, 75 and 100 mg L-1 of Fe2O3 NPs. Foliar spraying with Fe2O3 NPs improved the yield and biosynthesis of bioactive compounds in cucumber fruits, increasing the yield by 38.99%, the biosynthesis of compounds by 30.18% and an increase of 23.26% of Fe in fruits. Foliar spraying of Fe2O3 NPs is an alternative to increase agricultural production, decreasing Fe deficiency, while improving the biosynthesis of bioactive compounds in order to ensure food and nutrition security.
