The nutrition of the plant has an important function in the appearance and susceptibility of the crop. The present work intends an analysis of the state of the art regarding of the effect of the mineral nutrition, in particular the primary macroelements about the susceptibility to diseases. The revision behaved by means of the study of original scientific articles and bibliographical revisions, published in Cuban and foreigners; as well as the works carried out as thesis in universities of the region and of the world. Although there are some contradictions, the primary macroelements can affect tolerance and / or resistance to plant diseases caused by various pathogens. The most observed effect is the decrease in the symptoms of the disease except for the nitrogen, the one which in excess or deficit leads to higher incidence in the increase of susceptibility. An appropriate supply of the fertilization that promotes the good growth of the plants is an element to consider for the resistance to diseases.

Palabras clave : diseases; mineral nutrition; resistance; tolerance.
