Abstract

On an apple grove situated at Buri, State of São Paulo, fruits were collected from trees 1-2; 3-4; 4-5, and 6 - 7 years old. The fruits were analysed for N, P, K, Ca, Mg, S, B, Cu, Fe, Mn and Zn. The authors concluded: a) the concentrations of the nutrients in the fruits differ according to the variety, age of the tree and age of the fruit; b) the concentrations of nutrients decrease with aging of the fruits; c) the concentrations of the macronutrients obey the following order: N>;K>;P>;Ca>;S>; Mg; d) for the micronutrients, the following order was ob -served: Fe >; B >; Mn >; Cu >; Zn.
