Foliar Fe application boosts broccoli nutrition and productivity for global health.
Iron deficiency is a common problem worldwide, leading to anaemia. Scientists studied how adding iron and nitrogen to broccoli plants affects their growth and nutritional value. They tested different methods of applying iron and nitrogen to the soil and leaves. The results showed that applying iron directly to the leaves, especially with nitrogen, increased the weight and size of the broccoli florets. It also boosted the iron content in the florets, making it more available for our bodies. This method not only improved the plant's productivity but also increased its antioxidant and polyphenol levels, making it healthier for us to eat.
