In this paper are presented some researches concerning depth of the plantation of the roots horizontal of the variety ”Centenar” plum tree, from the plantation created on the Experimental Station Banu Mărăcine. The researches had been achieved in the autumn of the year 2006, at the variety Centenar plum tree, grafted on 4 rootstocks, respectively: Oteşani 8, Pixy, Miroval and Roşior văratec, and the method of study it was used the profile method. We found out that the maximum depth of the horizontal roots development is of 90 cm, the most roots we can found to the 30-60 cm depth. As a result we suggest the depth of working in the orchard to be normal and the incorporation of the organic fertilizers must be realized once with autumn ploughing.
