A study was made on the accumulation of dry matter, concentration, and uptake of macronutrients in the cultivar Santa Rosa, in sucessive stages of growth. The sampling of the above ground parts was done at intervals of 20 days. The soil was a Terra Roxa with latossolic B under cerrado vegetation. The maximum of dry matter accumulation occurred at 90 days after germination with a production of 5632 kg/ha. The same was observed for calcium, magnesium and sulphur whose uptakes were 58.7, 27.8 and 9.3 kg/ha respectively. The maximum uptake of potassium, which was 80.2 kg/ha occurred at 110 days whereas those of phosphorus and nitrogen occurred at 130 days and reached 12.9 and 146.1 kg/ha respectively. Of the total amount of macronutrients retained by the plants (excluding roots and fallen leaves) the seeds contained 92.5% of N, 83.7% of P, 58.7% of K, 16.0% of Ca, 21.9% of Mg, and 43.0% of S respectively.
