Um experimento foi conduzido em Jaíba (MG) para avaliar o crescimento e o acúmulo de nutrientes pela abóbora híbrida, cv. Suprema. As amostragens de plantas foram realizadas aos 28; 42; 56; 70; 84 e 98 dias após a semeadura (DAS) para determinação da matéria seca das folhas, caule, flor, fruto e raiz. A planta teve lento crescimento até 56 DAS e a partir daí o crescimento intensificou-se até o final do ciclo. A produção total de matéria seca máxima ocorreu aos 89 DAS, atingindo 1.657,92 g planta-1. Os frutos acumularam mais matéria seca que outros órgãos da planta. A taxa de crescimento absoluto da planta e dos frutos foram 124,25 e 172,75 g planta-1 dia-1, aos 74 e 79 dias, respectivamente. A absorção de nutrientes seguiu o padrão da curva de acúmulo de matéria seca pelas plantas. O acúmulo de nutrientes foi reduzido nos primeiros 42 DAS, intensificando-se a partir daí, acumulando continuamente até o final do ciclo para N, S, Mg e os micronutrientes. O K foi o nutriente mais absorvido pela planta, seguido do N e Ca. A ordem de macronutrientes acumulados foi K>N>Ca>P>Mg>S e de micronutrientes foi Fe>Mn>Zn>Cu. Na colheita, aos 98 DAS, 69% da matéria seca alocou-se nos frutos, 19% nas folhas, 8% no caule, e o restante nas flores e raízes. Os nutrientes N, K, S e Cu acumularam-se preferencialmente nos frutos, enquanto o P, Ca, Mg, Zn, Fe e Mn na parte vegetativa. Os frutos exportaram 51,0 kg ha-1 de N; 12,4 kg ha-1 de P; 61,4 kg ha-1 de K; 3,6 kg ha-1 de S; 8,8 kg ha-1 de Ca e 3,5 kg ha-1 de Mg, e 11,4 g ha-1 de Cu; 61,6 g ha-1 de Zn; 126,6 g ha-1 de Fe e 44,3 g ha-1 de Mn. An experiment was carried out at Jaíba, Northern Minas Gerais State, to evaluate the growth and accumulation of nutrients in hybrid squash cv. Suprema. The samplings of plants were taken at 28; 42; 56; 70; 84, and 98 days after the sowing (DAS) for dry matter determination of leaves, stem, flower, fruit and root. The plants grew slowly up the 56 DAS, intensifying thereon. The total production of maximum dry matter occurred at 89 DAS, reaching 1657.92 g plant-1. The fruits accumulated more dry matter than the other organs of the plant. The rate of absolute growth of plants and fruits were 124.25 and 172.75 g plant-1 day-1, at 74 days and 79 days, respectively. The nutrient absorption patterns followed the plant dry matter accumulation. The accumulation of nutrients was low in the first 42 days, intensifying thereon for N, S, Mg, and the micronutrients. K was the nutrient more absorbed by the plant, followed by N and Ca. The order of accumulation of nutrients was K>N>Ca>P>Mg>S and Fe>Mn>Zn>Cu. In the crop, at 98 days, 69% of the dry matter was allocated in the fruits, 19% in the leaves, 8% in the stem, and the remaining in the flowers and roots. The nutrients N, K, S, and Cu accumulated in the fruits, while P, Ca, Mg, Zn, Fe, and Mn accumulated in the vegetative part. The fruits exported 51.0 kg ha-1 of N; 12.4 kg ha-1 of P; 61.4 kg ha-1 of K; 3.6 kg ha-1 of S; 8.8 kg ha-1 of Ca and 3.5 kg ha-1 of Mg, and 11.4 g ha-1 of Cu; 61.6 g ha-1 of Zn; 126.6 g ha-1 of Fe and 44.3 g ha-1 of Mn
