The cultivation of irrigated common bean is an important economic activity for the city of Cristalina, Goias. The proper management of manure promotes the production of safer, contributing to the economic and environmental sustainability. The Diagnosis and Recommendation Integrated System (DRIS) was developed to provide a diagnosis of the nutritional status of cultivated plants, helping the decision on fertilizer recommendation for crops, being based on the balance of essential nutrients to plants. However, this study aimed to establish reference standards DRIS and assess the nutritional status of irrigated common bean grown in the municipality of Cristalina, GO. In this, there were 86 samples of soil samples, 86 samples from leaf samples and 82 samples of common bean yield in 2009/2010. With the data organized into a database. The database was analyzed from two aspects known as the traditional methods of Critical Levels and Concentration Ranges, and also by the method of DRIS. The attributes B, S, MO and T were considered insufficient, while nutrients Cu, Fe, Mn, Zn, K and P were considered excessive in the soil. Fe, Zn and Mo were the nutrients in the leaves with smaller amplitudes located within the range considered appropriate, nutrients S, Ca and Cu were considered insufficient, and the P, N, and K have been considered excessive in the plant, comparing the criteria established. The DRIS method was more sensitive to diagnose nutritional problems, especially for micronutrients
