Abstract: The present study aimed to determine the curves of accumulation of dry mass and macronutrients in grain sorghum in the off-season period. For this, a field experiment was installed in an Oxisol in the municipality of Janauba-MG using the grain sorghum hybrid DKB599. A randomized block design was used, with four replications to determine the course of macronutrient uptake (N, P, K, Ca, Mg and S ) and dry matter accumulation. in stems, leaves, panicle and grains. The off-season grain sorghum (DKB 599) reaches the maximum accumulation of dry mass and macronutrients during the stage of hard grains, the end of the cycle. The accumulation of macronutrients in the shoots presented the following descending order: K> N> Ca> P> Mg> S.
