          Abstract

          Foi efetuada uma série de 31 experimentos utilizando a técnica de microparceIas, sendo o milho a planta teste, para estudar a fertilidade dos solos da região produtora de côco do Estado de Sergipe. As principais conclusões foram: a. O nitrogênio e o fósforo são os fatores que mais limitam o desenvolvimento das plantas. b. As respostas às omissões de K, Ca, Mg, S e micronutrientes mostraram grandes variações nas áreas estudadas indicando a necessidade de pesquisa mais intensa. c. É necessário estudar o efeito do calcário dolomítico no equilíbrio entre os cátions para melhor caracterizar as deficiências de alguns nutrientes.

          Translated abstract

          Thirty one experiments, using the corn plants microplot biological techinique, were conducted to study the fertility status of soils representative for the production of coconuts in the State of Sergipe. The results obtained allowed for the following conclusions: 1. Nitrogen and phosphorus were the nost limiting factors for the growth of the plants. 2. The responses to omiting potassium, calcium, magnesium, sulfur and micronutrients showed great variation in the different areas studied, indicating the need for greater studies. Is is likewise indicated the need to study the effect of dolomitic limestone in the equilibrium between cations in order to better characterize the defficiencies of some nutrients.
