The experiment was conducted at the Technical Center for Irrigation, Maringá State University. The objective was to evaluate the effects of different water regimes (irrigation and no irrigation) and fertilization-irrigation, combined with different manure doses for N (15; 30; 45 and 60 g m-1), P (3; 6; 9 and 12 g m-1) and K (15; 30; 45 and 60 g m-1), during the initial growth phase of two coffee cultivars, in the north-western region of the state of Paraná. The following culture growth variables were evaluated: top diameter, height of plant and number of total plagiotropic branches. Fertilization-irrigation and irrigation affected the initial development of coffee, increasing the values of all evaluated variables. Interaction between water regimes and fertilization-irrigation with NPK doses was significant for certain growth variables, however results didn't present a common trend, that would indicate which dose was adequate for each water regime during the initial growth phase of the coffee shrub.
