The usage of modern technologies not been used much for the citrus growers, most of them like to grow tangerine tree citrus growers, most of them like to grow tangerine tree in (old way) the traditional way, leading the tree´s top volumes to increase, without worrying about the uncontroled growth of the plant which difficult and increases the expense of the right cultural treatments, mainly the harvest. Therefore, the lacking of right cultural treatments usage, such as pruning, can compromising the yield, physical and organoleptical qualities of the fruit. So, this research aimed to test top pruning effect in the lowering of the top and pruning the lower part of the plant in the recovering of 12 years old " Ponkan" tangerine tree, 4 meters height, 6x4 spacing grafted on ´Cravo´ lemon tree. This experiment was carried out at Vito Crincoli´s Farm in Perdões - MG . It was used randomized plots in a factorial scheme of 4x2, top pruning (without pruning, pruning at 3.0; 2.5 and 2.0) and pruning circumference (with and without pruning) with 4 replications. The useful parcel used three plants. It was verified after the third year of pruning that the plants showed a growth that, statistical, did not differ anymore from the control, showing to be recovered from the pruning treatments. Those dramatically pruning of the top of the plant damaged the first tree yield, therefore, after the second year pruning, the plants showed a very good recovering. This affirmative was confirmed in the third harvest when several kinds of pruning the top did not differ in the yield, the pruning treatment of the lower part of the tree was superior to that without any pruning. After the third year the plants that had been under a more severe pruning gave higher fruit weight. According to the results, it was verified that the pruning quality, in those three following harvest.
