It was developed an experimental at Faculdade de Ciências Agronômicas of UNESP, with the objective of evaluating the effects of differents irrigation levels in the cultivation potato, cultivar aracy. It was used sets at random as the experimental design with five treatments, five plant collection for growth analysis and four replication. The treatments consisted of irrigation the potato when the soil water potential reached 15, 35, 55, 75 and 1500 kPa. The result showed that the increase in the irrigation levels induced a rise in the total plant dry matter, in the dry matter tuber and the leaf.
