Carrot ( Daucus carota ) is a highly nutritious food, ideal for food and human health. Production has increased in recent decades and currently the world harvests more than 44 million years annually. Fertilizers are essential to improve crop response and productivity. Organic sources have been enriched with mineral sources, forming organominerals, which promote several benefits to the soil and plant nutrition. Even so, new studies investigating fertilizers, the nutritional balance of the crop and its effects on the production system are needed. Therefore, the objective was to evaluate the production of carrots under the application of organomineral fertilizer in the soil, using the hybrid Verano, under the conditions of Cristalina GO, city in the central-west region of Brazil, with semi-humid tropical climate. The experimental design was in randomized blocks with five treatments: control (mineral fertilizer at a dose of 100% of the recommendation for the standard crop on the property) and four treatments of organomineral fertilizer (100; 80; 60 and 40% of the recommendation). There was a significant difference in productivity related to the classifications of the vegetables harvested with the evaluated sources of variation. It was concluded that fertilization with 100% and 80% organomineral showed similar returns to those obtained with 100% mineral, both for total productivity and for total commercial. In addition, they provide lower rates of disposal, thus reducing losses in profitability in the production context.
