With the objective of evaluating the growth of three cultivates of carrot, it was done an experiment, from June until September, 2006, in the Vegetable garden of the "Departamento de Ciências Vegetais" of UFERSA, Mossoró-RN. This work was delineated in factorial scheme 8x3 in randomized blocks, with four repetitions. The first factor constituted by the times of collections of plants was: 7, 14, 21, 28, 35, 42, 49 and 56 days after polish, and the second for the cultivars: Brasília, Alvorada and Esplanada. The used spacing was 20cm among arrays and 4cm among plants. The characteristics evaluates were: number of leaves; dry mass root, leaves and total, foliate area, foliate area index (FAI), foliate area reason( FAR), relation part air/root and for the rates of relative growth (RRG) and absolute (RAG). The number of leaves, the foliate area, the dry mass root, leaves and total, RAG and FAI increased while FAR, relation part air/root and RRG refused, in the experimental period, for all the cultivates evaluated. The cultivates presented similar behavior with the relation to the characteristics: number of leaves, foliate area, dry mass leaves FAI, RRG and RAG. The mass accumulation of dry mass root it went superior for cultivars Alvorada and Brasília in relation to the Esplanada, for occasion of the harvest, in the 56 days after polish.
