For the adequate management of a crop, especially perennial fruit tree, the knowledge of some agronomic factors becomes important, among them the development and the distribution of the root system. The objective of this work was to evaluate the distribution of the root system of the mango Coquinho rootstock, on top of Haden mango cultivar. The study was conducted between March/05 and May/07, in a clay soil, dystrophic Red Latosol (Haplustox), in an orchard implanted in 1992, spacing of 10 x 10 m, at Experimental Station/Unesp/Ilha Solteira, located in Selvíria-MS State. The treatments were: control plants (no lime added) (T1) and plants that received 3.1 t of lime ha-1 (T2). The root system, was evaluated through samples collected in the depths of 0.0-0.20; 0.20-0.40; 0.40-0.60; 0.60-0.80 and 0.80 to 1.0 m and from the trunk of 0.83; 2.49; 4.15 m, and the roots were classified into < 2; 2-5; 5-10 e >10 mm. The largest occurrence of absorption roots where those with a diameter smaller than 2 mm in both treatments T1 and T2. The biggest concentration of absorption roots occurred between zero and 1.66 m from the trunk and zero and 1.0 m of depth. The biggest concentration of absorption roots occurred at two first layers of the ground (0.0-0.40 m). Plants that received lime increased 15.73% of absorption roots than plants without lime.
