The pecan Carya illinoinensis (Wangeh.) K. Koch is a fruit tree in domestication process, and the components of its profitable and sustainable management are continuously generated by research (Wood, 1991, 2006). For the soil management, the plants that grow on it are traditionally cataloged under the “weed” concept, which states that they must be eradicated by farming and/or application of herbicides. Nevertheless, by knowng the specific benefits and disadvantages of a cover of native plants, they can be integrated as a component for management of hickory plantations.
Key words: Pecan tree, sustainable, nutritional state.
