Descripción
Study to evaluate of cupuacu in an agroforestry system ((cupuacu, pupunha, seringueira-rubber tree, mamao-papaya, pueraria) with different fertilizer levels, in the Manaus-AM (Brasil). Comparing the agre of the leaves, the largest concentration of N were found in the intermediate leaves, and the lowest concentration were found in the old leaves. The contents of P and K decreased with the age of the leaf. For the new and intermediate leaves, the lowest concentration of P was observed in the treatment 30% N. The P contents were not influenced by the different fertilization levels.
