The objective of this work, is to evaluate the growth components of castor cultivars under irrigation conditions in the region of Mossoró, Rio Grande do Norte State, Brazil. For both, used to the design in blocks randomized, and the treatments consisting of castor cultivars CSRN-142, CSRN-393, CSRD-2, CNPAM-2001-49, CNPAM-2001-50-2001-and CNPAM 212) and times of assessment (to 29, 40, 50, 64 and 78 days after planting - DAP), arranged in the scheme split plots 6 x 5, with six repetitions. The growth was measured by plant height (HP), the stem circumference (CIRC) and leaves number per plant (NL). Cultivars differ among themselves about the growth characteristics in all seasons studied, except for the first timemaking data for HP and NL. The CNPAM-2001-49 and CNPAM-2001-50 showed, in general, very similar behavior, and cycles with size larger than the CSRN-142, CSRN-393, CSRD-2.
