The inexistence of organic seeds in the market and the absence of information constitute a difficulty for the organic production. The green fertilizer efficiency (GF) was evaluated, of organic compound (OC), and biofertilizer (B) in carrot production and seeds quality, compared to conventional fertilizer (CF-control), through the treatments: 1) CF; 2, GF+B via soil; 3) GF+B via plant; 4) OC+B via soil; 5) OC+B via plant; 6) OC+GF+B via soil and 7) OC+GF+B via plant. Higher morphological values (height, length and diameter), of germination and vigor were given by treatment 5, while production and total soluble solids reached higher gradients when growing plants with treatment 4, upper data of treatment 1. Treatment 3 resulted in root production with lower number of branches nematode. Carrots of preview treatments 2 and 6 were classified in a lower size. Decomposition of GF, linked to B applied to the plant, may have given a higher carrot resistance to nematodes and better commercial classification. Organic treatments resulted in better roots and seed quality and higher production.
