Excess fertilizer, whether organic or mineral, can promote several nutritional disorders in the apple plants, affecting the production and fruit quality. The objective was to evaluate the effects of sources and doses of N and of supplemental K and P on foliar and fruits mineral composition of ?Daiane? apples. During nine years, the eight treatments tested were a check and soil application of three levels of N as ammonium nitrate (AN), one level of N as poultry manure, one level of AN plus K, one level AN plus P and K, and one level of N as calcium nitrate, via annual soil applications. Macro and micronutrients were determined in leaves sampled at eighth and ninth years after planting, and Ca, K, Mg, N and P in the fruit flesh sampled at seventh, eighth and ninth years after planting. An annual poultry manure application increased the P, K and B content in leaves and apple fruits in comparison to the control. Annual application of 60 kg ha-1 de K2O and 75 kg ha-1 of N also increased the K content in leaves and fruits. The P and K content and the (K+Mg)/Ca relation in fruits were increased with annual application of 75, 20 and 40 kg ha-1 of N, K2O e P2O5, respectively. High doses of whether organic or mineral fertilizers affect the foliar and fruits mineral composition of ?Daiane? apples, which can compromise the fruit quality by increasing the risk of physiological disorders. |
