: The objective of the work was to make a preliminary evaluation of the response of the castor bean culture in compacted soil and to serve as a basis for future evaluations in field condition. The experiment took place at the Instituto Federal de Mato Grosso - Campus Campo Novo do Parecis with a Latossolo Vermelho distrófico típico with a clay texture. The experimental design used was completely randomized, with 4 treatments, with soil densities: 1.0 Mg m-3; 1.2 Mg m-3; 1.4 Mg m-3 and 1.6 Mg m-3 and 6 repetitions. The experimental unit consists of a 0.2 m high vessel, formed by the overlap and assembly of two rigid PVC rings with a height of 0.1 m and an internal diameter of 0.17 m. The characteristics evaluated in the castor were stem diameter, plant height, number of leaves fixed on the plant stem, dry mass of the aerial part, dry mass of the root, total dry mass, height/diameter ratio, height/dry mass ratio of the part aerial, height/dry mass ratio of the root and dry mass of the aerial part/dry mass of the root. The castor crop is sensitive to the increase in soil density, and further studies with extrapolation for the field condition are recommended.
