Abstract

Fig (Ficus carica L.) is widely accepted due to its organoleptic and pharmacological properties. Search for innovations to improve the crop management has increased to reduce environmental impacts and improve the organoleptic quality and food safety of the fruits. Thus, this study aimed to evaluate the influence of fertilization methods and plant training systems on the production and physicochemical traits of fig. The experiment was carried out in a randomized complete block design in a 5 × 4 factorial scheme, with three blocks and three plants per plot. The factors corresponded to five fertilizers (chemical, cattle manure, sheep manure, poultry litter, and organic compost) and four training systems (two branches, three branches, four branches, and espalier). Results showed that, when using chemical fertilizer and poultry litter, plants showed similar productivity and number of fruits, which had similar firmness, length, and peel color (L and °h). The highest production and number of immature fruits were obtained using cattle manure. Soluble solids content and soluble solids content/ titratable acidity ratio were higher in fruits from plants fertilized with cattle manure, sheep manure, and organic compost. On the other hand, plants trained with three and four branches or in espalier produced fruits with the highest soluble solids content and weight. Also, heavier fruits were obtained using chemical fertilization and conducting plants with two, three, and four branches.
