%X Com objetivo de avahar o crescimento e a marcha de absor  o de nutrientes (N, P, K, Ca, Mg e S) em tr那s cultivares de amoreira (tratamentos), colheu-se quatro plantas por tratamento, em diferentes estadios fenol車gicos. O delineamento experimental utilizado foi inteiramente casualizado, em esquema fatorial 3x5 em 3 repeticSes. As cultivares usadas foram 'FM Shima-Miura', TZ 56/4' e 'Miura' e estabelecido cinco 谷pocas de colheita da biomassa 45; 60; 75; 90 e 115 dias ap車s a cepa. Observou-se que o acumulo de nutrientes apresentou comportamento diferente e a cv. IZ 56/4 foi superior comparado com 角s cv. PM Shima-Miura para N, P, K, Ca, Mg e S e Miura para N, P, K e S. Por exemplo, o acumulo de N em mg por planta-1 planta de amoreira das cultivares PM Shima-miura, IZ 56/4 e Miura foi respectivamente 4,21; 8,14 e 5,56. Para o K 2,71; 5,22 e 2,64. Para o Ca 2,47; 4,52 e 3,59. To evaluate the growth and pattern of nutrient absorption (N, P, K, Ca, Mg and S amongst others) in three berry cultivars (treatments), four plants by treatment in different phonological stages were harvested. The experiment was arranged in randomized design of factorial 3x5 with three replicates. There cultivars were used FM Shima-Miura, IZ 56/4 and Miura and above ground biomass was harvested in five occasions 45, 60, 75, 90 and 115 days after plantation. It was observed that the accumulation of nutrients presented different pattern and cv. IZ 56/4 was superior compared with PM Shima-Miura for N, P, K, Ca, Mg and S and N, P, K and S for Miura. For example, the accumulation of N expressed on mg plant"1 per berry plant cultivar PM Shima-miura, IZ 56/4 and Miura was respectively 4,21; 8,14 and 5,56, for K 2,71; 5,22 and 2,64 and for Ca 2,47; 4,52 and 3,59.
