Effect of planting date on postharvest quality of roots of different carrot cultivars grown in the Brazilian semiarid region

The chemical composition of carrot roots is variable and influenced by genetic factors and cultivation conditions, such as crop system, soil type and physical properties, planting time, rainfall, and temperature during the growing season (Seljåsen et al., 2013), as well as phytosanitary aspects, fertilization, and planting density. [...]understanding the environmental conditions in different regions and climates where a crop is grown is crucial when choosing a cultivar. Additional research is needed due to the difficulties of carrot production in warm and lower elevation regions, starting with the selection of cultivars with genetic potential for quality root production under high temperatures. [...]it is assumed that the planting date influences the postharvest quality of carrot roots due to climatic and environmental variations, such as precipitation, temperature, and cloudiness. Results are presented in Table 2. Since the experiments were carried out in adjacent areas, only a composite sample was taken from the experimental area for analysis.
