Abstract

Rice plants cultivar L-45, a mutant obtained by Dr. A. Ando, Piracicaba, were grown in nutrient solution until maturity. At intervals, fixed to coincide approximately with physiological stages of development, samples were taken for analysis of dry matter production and nutrients accumulation. It was verified that maximan rate of uptake occurred from 64 to 106 days after germination which corresponds to full tillering and beginning of maturation. Nutritional requirements obeyed the following depreasing order: macronutrients - N, K, Ca, P, Mg and S; micronutrients - Mn, Fe, Zn, Cu and B. Export of macronutrients occurred in the same order, were as in the case of micronutrients it was: Mn, Zn, Fe, Cu, and B.
