Effects of nitrogen fertilizer rates and within-row spacing on carrot root yields and root characteristics


  • To evaluate the effects of 5 nitrogen rates and 2 within-row spacings on yield and root characteristics of Royal Chantenay carrots at North Willamette Experiment Station and Oregon State University Vegetable Research Farm.
  • To evaluate the effects of supplemental nitrogen rates, in addition to grower's base rates of N on yield at 5 grower locations (Red Cored Chantenay).
  • To determine N concentrations in carrot leaf sample from each of the experimental locations.
