The utilization of foliar fertilizers has become a fundamental management tool in intensive and super-intensive orchards. For this experiment, five peach genotypes ("DDD 67", "Maria Bianca", "Eureka", "HB 19-9" and "Tokinostate") were studied. Each genotype was treated with four different foliar fertilizers, two organic and two chemicals, during three separate growth phenophases. The genotypes were divided into five groups from which one group functioned as the experimental control and received no foliar treatment. In the case of the analyzed genotypes, the fertilizers, especially the biological ones, had significant positive influences on the internal characteristics of the fruits. Regarding the soluble solid content, in all genotypes, except "HB 19-9", better results were obtained in the case of biological fertilizers usage, especially the Cropmax fertilizer. The highest values of total polyphenol content, in all genotypes, except "Eureka", were also obtained in the case of biological fertilizers usage.
