Abstract

Iodine is an essential micronutrient for human health, particularly due to its critical role in thyroid metabolism. Its deficiency can lead to goiter, hypothyroidism, and neurological disorders in children. This study evaluates and compares the effects of iodine on photosynthetic pigments and bioactive compounds in the peanut plant (Arachis hypogaea L.). Five iodine concentrations (0.000, 0.050, 0.100, 0.150, and 0.200 mM L-1) were examined across four treatments and one control through foliar spraying 90 days after transplanting. The response variables included photosynthetic pigments (chlorophyll a, chlorophyll b, total chlorophyll, and carotenoids) and bioactive compounds (total carbohydrates, total anthocyanins, and antioxidant capacity). The results show that the 0.200 mM L-1 concentration produced significant effects in bioactive compounds and performance, surpassing values reported in studies. These findings indicate that iodine application can serve as an effective strategy to enhance the nutritional quality of crops and contribute to mitigating micronutrient deficiencies in human populations. Furthermore, inoculation with nitrogen-fixing bacteria supports greater agricultural productivity while reducing dependence on inorganic fertilizers. Overall, this research provides valuable insights for strengthening food security.
