The citros crop in Bahia and Sergipe, represents about 103.000 hectares and is established in the Coastal Table Land, where Yellow Latosol prevail, with cohesive horizons that become hardned when dry. This problem restrains the development of the roots along the profile of the soil, promoting the decrease of soil volume explored and consequently the availability of water and nutrients. To solve this problem, breaking the cohesive layer and increase the volume of soil roots it was used several depths of planting with holes of 0,40; 0,60; 0,80; 1,00 and 1,20 m, using orange tree 'Valência' grafted on lemon tree 'Volkameriano'. The best development of the roots was obtained with the 1,00 m and 1,20 m of depth. No significant statistical results was obtained for diameter of the cup and the stem, plant height and production of fruits among the treatments.
