The objective of this study was to evaluate the nutritional state of 20 different genotypes of common bean, which were six cultivars and 14 breeding lines. The experiment was conducted in the field, between August and November of 2002, in an Oxysoil, Cristalina – GO, Brazil. Yield and leaf diagnosis were evaluated, 45 days after the emergence of the culture (total foliar rates of N, P, K, Ca, Mg, S, B, Mn, Cu and Zn), by the DRIS method, using the nutrient concentrations, taken two by two. Nutrient absorption was different for the genotypes. In most of them, Zn was the less absorbed nutrient, while S was the nutrient in excess. DRIS correlation was different for nutrient interactions, as for a positive correlation for P x Zn (0,928), as for a negative correlation, for N × S (-0,947). DRIS shows nutrient deficiency and nutrient excess, for manure recommendations, and it can be used as a routine for bean culture, based on a leaf diagnosis.
