Nitrogen Rates and Phosphorus on Carrots (1986)

Higher yields and improved root quality are essential for processing carrot growers to remain competitive. Nitrogen fertilizer applications range from 50 to 150 pounds N/acre with most between 50 and 80 pounds. More research is needed to clarify yield response to nitrogen, especially at higher rates, and the influence of N on such root characteristics as diameter, length, splitting, and rots. The response to N should be investigated at plant densities typically used for slicing and dicing.
