Resumo
Brazil occupies a leading place in the world’s citrus culture, Pêra orange being the most planted
cultivar because it meets both the industry and in natura market. The nutrient diagnosis is fundamental to the management
of a citrus orchard, for the nutrient management is an important production factor, mainly on the cerrado where the soils
present a high acidity and low reserve of nutrients. With the objective of diagnosing factors the most limiting to the
obtaining high yields for orange culture, by the soil and leaf analyses, interpreted by the concentration ranges in
commercial areas in the central region of Goiás, orchards were screened in the towns of Inhumas, Goiânia and
Goianápolis. Each orchard was divided into glebes, each glebe was made up of 4 Pêra orange plants grafted on cravo
lemon, seeking to maintain uniformity within the glebes and differences among them. In the whole, 303 glebes were
evaluated in 2004. In each glebe, yield was estimated, soil samples and leaf samples were collected on fruit-bearing
branches. The leaf analyses and soil analyses pointed to diagnoses of the discordant. nutritional status Leaf analysis
indicated that the chief deficient nutrients were Zn, B, Ca and K and excess P, Cu, Mn, S and Fe. Soil analysis indicated
that the main deficient nutrients were: P, S, Ca and Mg and excess B, Mn, K, Zn and Cu.
