Due to the broad market prospects for crops in tamarind and pitombeira, it becomes essential the evaluation of methods that permit the propagation on a commercial scale. Considering this, two experiments were organized in a greenhouse, located in the Universidade Federal Rural do Semiárido UFERSA, located in the town of Mossoró, RN, from January 2009 until June 2010, with the objective of determining the best grafting method for the production of seedlings of tamarind and pitombeira. We studied the types of grafting: grafting in top cleft, cleft grafting in the top simple English way , grafting in the top complicated English way , grafting budding side and plate cleft. The design used in the experiments was a randomized complete block with five treatments (grafting types). The experiment with tamarind had seven repetitions; each parcel consisted of 14 seedlings, a total of 98 per treatment, adding 490 in the experiment. Variables were evaluated: percentage of grafting success, shoot length, root length, branch length, number of leaves, number of branches, stem diameter, shoot dry matter, root dry matter, Total matter dry. The data were subjected to analysis of variance and compared through the Tukey test at 5% significance using the software SISVAR. The rates of graft takes were submitted to angular transformation of arcsen √ x/100, and data on the number of branches in √ x + 0.5. In order to promote the statistic, treatment of pimple on board was disregarded, considering that this treatment has zero index of plant take. The grafting methods in top cleft, cleft grafting in the English top grafting complicated and simple English way in the top, are respectively the best methods of grafting for the tamarind. The test was conducted with pitombeira with four replications and each plot was composed of twenty seedlings in a total of 400 seedlings on the experiment, in which was observed zero rate of grafting take
