The researchers studied biofortified wheat to help fight zinc deficiency in people, especially in developing countries. They tested different wheat genotypes in Pakistan and India with various zinc fertilization methods. The biofortified wheat absorbed and stored more zinc in the grain compared to regular wheat. By using a combination of soil and foliar zinc fertilizers, the biofortified wheat showed a significant increase in both yield and zinc concentration in the grain. This approach can help improve crop productivity and increase zinc levels in wheat, which can help combat malnutrition in regions with zinc-deficient soils.
