Since the ‘Cerrado’ area of Piaui State, Brazil is a relatively new agricultural frontier, there is lack of information regarding the handling of potassium fertilization, since no information about the better fertilization techniques for this area was provided by the federal research corporations. Thus, the aim of this study was to evaluate the effect of dose and time of application of K2O in corn grown in a ‘Cerrado’ area at the Paui state. The experiment was conducted in a yellow dystrophic oxisol with a completely randomized block design, with four repetitions in a (4x4)+1 factorial. The treatments consisted of combinations of four potassium levels: 30, 60, 90 and 120 kg ,K2O ha-1 + additional control (zero kg ha-1) applied in four seaso...
