The present investigation was made in the Experimental Farm "La Pradera", located in the province of Imbabura, the parish of San José de Chaltura, to 1350 meters above sea level and an average temperature of 16, 4⁰ C. To analyze the effect of the chemical and organic fertilization in amaranth of variety INIAP "Alegría" was the primary target of the investigation. The field work was made in a lapse of 6 months. The design of complete blocks (DBCA) with 15 treatments was used at random and three repetitions by treatment. The experimental unit was 18 m². It was evaluated by means of analysis of variance and the Turkey test at 5%. The factors in this study are constituted by the elements N, P, S and organic fertilizer. The analyzed variables were: number of plants; days to the flowering; days to the harvest; height of plants; biomass; extraction of nutrients; and grain yield. The number of plants presented significant difference to 1% for treatments and to 5% for blocks, the treatments that reached the greater number of plants are T11 (80-60-40-0) and T14 (0-0-0-10) with an average of 30 and 29 plants of amaranth in 0.50 linear m respectively. The treatment T4 (120-60-20-0) presented the greater height at 45 days of seedtime, with an average of 24.10 cm. The height of plants at flowering I present significant statistical results highly is the T4 (120-60-20-0) and T5 (160-60-20-0) respectively present values of height of 119.30 and 103.40 centimeters. The height of plants at the harvest determines significant difference for treatments the highest being the T5 (160-60-20-0), the one that reached the greatest height with an average of 148, 11 centimeters. The days to the flowering of the amaranth were between 70 and 85 days from seedtime and the days to the harvest were between 143 and 152 days. The treatment that reached the greater mean efficiency was the T5 (160-60-20-0) with 2583, 69 Kg/ha unlike the control who reached an average of yield of 686, 66 Kg/ha. In the organic treatments the greater yield registry in T15 (0-0-0-15) where 15 tons of organic fertilizer by hectare was used resulting in 1672.59 Kg/ha.
