Carrot seeds vigor on plant performance and crop yield

Rapid emergence and uniform seedling growth are essential attributes in the production of vegetables such as carrots, whose sowing is direct field. The experiment was conducted to evaluate effect carrot seed vigor on emergence, plant development, yield. Four lots carrot, cv. Brasília were characterized for their physiological potential by germination tests. A field conducted, where seeds each lot sown at 10 14 days, length shoot root 30, 45 60 days after sowing, crop rate, commercial, non-commercial commercial total roots Seed significantly affected development plants less vigorous showed lower final than most these negative effects extended advanced stages development. Carrot affects Vigorous causes greater height dry matter during vegetative phase. use yield losses up 27%.
