Resumen
Descripción
Pecan farming has been expanding in Brazil, mainly in the south, where different practices and technological levels have been used in orchard management, a fact that is directly connected to nut production and quality. This study aimed at determining the quality of fruit borne by pecan trees grown in orchards that use three technological levels in Rio Grande do Sul state. The following variables were evaluated in the 2020/2021 season: number of fruit per kilogram, fruit mass, kernel mass, shell mass, kernel yield, fruit length, fruit diameter and percentage of fruit with imperfections. Fruit mass, kernel mass, shell mass, fruit length and fruit diameter were higher in the orchard that had high technological level than the other orchards. The lowest kernel yield and the highest percentage of fruit with imperfections were found in nuts borne in orchards that used little technology to lead and manage plants. Nuts produced in the orchard that applied the highest level of technology were significantly larger and heavier. It resulted in the lowest number of nuts to compose a kilogram. Therefore, this study shows that orchards that apply more practices and management produce the largest fruit with high mass and low percentage of imperfections, which determine high nut yield and quality.
