Previous issue date: 2013-08-30 / 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 / O cultivo do feijoeiro comum irrigado representa uma importante atividade econômica
para o município de Cristalina em Goiás. O manejo adequado da adubação propicia a produção de
alimentos mais seguros, contribuindo com a sustentabilidade econômica e ambiental. O Sistema
Integrado de Diagnose e Recomendação (DRIS) foi desenvolvido para fornecer um diagnóstico do
estado nutricional de plantas cultivadas, auxiliando na decisão sobre a recomendação de adubação
para culturas agrícolas, sendo baseado no balanço dos nutrientes essenciais aos vegetais. Este
trabalho teve por objetivo estabelecer as normas de referência DRIS e avaliar o estado nutricional
do feijoeiro comum irrigado cultivado no município de Cristalina, GO. Foram realizadas 86 coletas
de amostras de solo, 86 coletas de amostras de folhas e 82 amostras de produtividade do feijoeiro
comum na safra 2009/2010. Com os dados obtidos organizou-se um banco de dados. O banco de
dados foi analisado sob duas vertentes, o método tradicional conhecido como métodos dos Níveis
Críticos ou Faixas de Concentração, e também, pela metodologia do DRIS. Os atributos B, S, MO
e T foram considerados deficientes, enquanto que os nutrientes Cu, Fe, Mn, Zn, K e P foram
considerados excessivos no solo. O Fe, Zn e Mo foram os nutrientes nas folhas com menores
amplitudes, situadas nas faixas consideradas adequadas; os nutrientes S, Ca e Cu foram considerados
deficientes, e o P, N, e K foram considerados excessivos na planta, comparando aos critérios
estabelecidos. O método DRIS apresentou maior sensibilidade para diagnosticar problemas
nutricionais, especialmente, para micronutrientes.
