Evaluation of summer carrot cultivars in bed and ridge systems

Abstract

In Brazil, carrots are usually grown in beds 30 cm heigh and 1 to 1.8 width. Although widely used, these beds present problems regarding cultural practices and disease management, especially in spring/summer seeding. The aim of this study was to compare the agronomic performance of carrot cultivars in summer cultivation in bed and ridge. Ten carrot cultivars were evaluated in two experiments in strips (bed and ridge), in a randomized complete block design with three replications. Seeds were sown on November 23, 2021, in Brasília-DF. At 90 days, evaluation of foliar diseases was performed, and at 100 days, evaluation of characteristics related to root yield was carried out. Total production was higher in bed, but there was no difference for commercial production in the two cultivation methods. The ridge favored root development, providing a greater mean root mass. Cultivation in ridge did not reduce the incidence of foliar diseases in carrots, but proved to be an alternative for commercial production of summer carrots.
