Iron and zinc are essential micronutrients for both plant productivity and nutritional quality. Although Fe is the most abundant transitional metal in the world, its chemical properties hinder its availability to plants. The research aimed to compare different genotypes of aerobic rice for their iron and zinc content and measures their comparative losses among different genotypes, from brown to white rice. Quantification of Fe and Zn was estimated by using X-Ray Fluorescence Spectroscopy in brown and white rice. A significant difference was observed in loss of both micronutrients from brown to white rice. AM-72 had highest Fe and Zn content in brown rice and highest Fe content in polished rice whereas, IRJS-107 had highest Zn content in white rice. Lowest count of Zn content in case of both brown and white rice was recorded in BJ-23. Sebati and ARB-6 had lowest Fe content in brown and white rice respectively. Positive correlation was observed between Fe and Zn content. White rice was deficient in both essential nutrients Fe and Zn. The loss of micronutrients from brown rice to white rice was above 50% of Fe and approximately 30% to 50 % of Zn. There was a greater quantitative and cumulative loss in Fe content than Zn, suggesting that Fe is present comparatively more in the outer aleurone layer than Zn.
