Fertilizer experiments were carried out to study the response of the banana plant to mineral and organic fertilizers, and to soil correctives. The experiments were conducted at Caraguatatuba on two types of the soils generally used for the banana crop in the coastal areas of São Paulo State. The experiments were designed in randomized blocks with four replications. Eight treatments, including mineral fertilizers and meals, were compared. In case of liming four treatments were applied. The resulta from the experiments indicated that potassium induced a strong response, especially in the area called Sítio Ribeirão. A response to nitrogen was noticed only at Sítio Velho, where small quantities of this element were necessary. No response to phosphorus and lime was recorded. The application of meals increased the yields. The strongest response to meals was recorded at the Sítio Velho where castor bean meal induced a response twice that obtained with cotton seed meal.
