RESUMO

ABSTRACT This study aimed to evaluate the effect of organic fertilizers on production and quality of fruits and pseudo fruits on adult trees of Anacardium occidentale L. by a productive cycle. We established three treatments; organic fertilization (BIO), synthetic fertilization (SF), and unfertilized (UF). The number of panicles m-3, number of flowers per panicle and the number of fruits m-3 in the trees was measured. After harvest, physicochemical analyses were performed to fruits and pseudo fruits. Although the SF treatment promoted a greater number of panicles per unit leaf area (P < 0.05) on the other treatments, the yield (measured both as the amount of fruit-pseudo fruit m-3) was the same (P > 0.05) with BIO treatment. However, the amount of fruit (main marketed product) was higher in BIO (1.80 kg tree-1) compared to the other two treatments (SF = 1.35; UF = 1.09). The BIO treatment increased by 81% polyphenol content compared to unfertilized treatment. Similarly, fat content and titratable acidity were higher in BIO, compared to treatments without fertilization and synthetic fertilization (P < 0.05). It was demonstrated that the application of biofertilizer in a production cycle increases fruit production and modifies the chemical composition of seeds.
