Abstract

Rice plants, Dourado Precoce, were grown in nutrient solution in order to study its nutritional requirement as well as the accumulation of dry matter and macro and micronutrients (excet Mo) during the life cycle. Demand for mineral elements followed the following decreasing order: macronutrients -K, N, Ca, Mg and S; micronutrients - Fe, Mn, Cu, Zn and B. Dry matter yield reached a maximun 100 days after germination (DAG), whereas accumulation of elements showed the geghest values at largest (140 DAG).
