biostudies-literatureUnknown6(11)Botoman LZinc (Zn) deficiency remains a public health problem in Malawi, especially among poor and marginalized rural populations, linked with low dietary intake of Zn due to consumption of staple foods that are low in Zn content. The concentration of Zn in staple cereal grain can be increased through application of Zn-enriched fertilizers, a process called agronomic biofortification or agro-fortification. Field experiments were conducted at three Agricultural Research Station sites to assess the potential of agronomic biofortification to improve Zn concentration in maize grain in Malawi as described in registered report published previously. The hypotheses of the study were (i) that application of Zn-enriched fertilizers would increase in the concentration of Zn in maize grain to benefit dietary rPlant directe458https://www.ebi.ac.uk/biostudies/studies/S-EPMC9631327biostudies-literatureAgronomic biofortification increases grain zinc concentration of maize grown under contrasting soil types in Malawi.PMC9631327Ander ELYoung SDBailey EHLark RMNalivata PCMossa AWChimungu JGMunthali MWBroadley MRBotoman LfalseAgronomic biofortification increases grain zinc concentration of maize grown under contrasting soil types in Malawi.Zinc (Zn) deficiency remains a public health problem in Malawi, especially among poor and marginalized rural populations, linked with low dietary intake of Zn due to consumption of staple foods that are low in Zn content.
