Abstract	This work was carried out on a Typical Humitropept sandyloam soil at Santa Rosa experimental station, State of Merida, Venezuela, with the objetive of determining if part of total amount of nutrient (N P K) of carrot (Daucus carota L. cv. Colmar) requirements, supplied with chemical fertilizer, could be substituted for organic fertilizer (poultry manure – fertipollo) without decreasing significantly the crop yield. Five levels of poultry manure “E” (0, 5, 10, 15 or 20 t.ha-1) and four doses of chemical fertilizer “Q” (0, 50 Kg de N + 16.67 Kg de P2O5 + 66.67 Kg de K2O, 100 Kg de N + 33.33 Kg de P2O5 + 133.33 Kg of K2O and 150 Kg de N + 50 Kg de P2O5 + 200 Kg de K2O ha1 ) were tested using a split - plot arrangement of treatments in a randomized blocks design with four replications. The yield of marketable roots was significantly influenced by ExQ interaction proving that organic and chemical fertilizers complemented their effects to increase such a yield. Total roots yield and biomass of top production were significant and independently affected by the chemical fertilizer doses used.
