Resumo
The diagnosis of nutritional status of a plant or a crop depends upon of referential standards. This
work had the aim to obtain standard values (local norms) for nutrient rations, rather than the nutrient itself, from high
yielding populations to serve as reference in corn crop planted in 0.45 m row spacing. Soil and leaves samples were
collected and grain yield were evaluated in a commercial crop in order to diagnostic the limiting nutrients, deficiency or
excess, on corn planted in 0.45 m row spacing, at Hidrolândia, Goiás With the results of the analyses of corn leaves and
soil, the population was divided in low and high yielding groups. DRIS norms were established using a yield of 5000 kg
ha -1 to divide the data set into high and low yield subpopulations. The locally calibrated norms used to evaluate the
nutritional status of the corn, from the leaves analysis, were compared to the others authors in several places. The
geographic differences in DRIS norms were identified.
