Selenium plays a important role in regulating soil-plant ecosystem functions. Is an essential element with antioxidative activity however its presence in plants is scarce. In this context, a technical itinerary was implemented in the rice variety (Ariete) through foliar pulverization with two selenium concentrations (50 and 75g Se.ha-1) of sodium selenate (Na2SeO4) and sodium selenite (Na2SeO3). Regarding the interaction of Se with other nutrients namely Zn the contents were analyzed in paddy and refined flours. It was found that in the refined flours there was an antagonistic relationship with the element Zn: an increase of Se in the grain, 29.9 to 77.9 g Se.ha-1., and a decrease of Zn content from 16.6 to 9.01 g Se.ha-1.
