Descrição: dc.descriptionCarrot plants do not develop well in clayey soils. In its turn, the charcoal fine (CF), which is a residue composed of porous particles, has the potential to be mixed in the soil to reduce its density. However, there is no evidence that the application of CF improves carrot production in clayey soil. Thus, an experiment in pots was designed, consisting of 16 treatments composed of the combination of 5 sizes of CF particles (1-2 mm, 2-4 mm, 4-8 mm, 8-16 mm, 16-32 mm) with 3 volumetric rates of CF (25%, 50% and 75%, plus a control (soil alone), aiming to verify which situation promotes the better plant growth and production. It was observed that mixing CF into the soil decreases substrate density and increases substrate water retention. The results of this research also revealed that the highest yield (fresh and dry weight) of carrots was achieved with CF mixed with the soil at a rate of 50%, using a CF particle size of 2-4 mm. The greatest length and diameter of carrots were obtained with a dose of CF of around 45%. CF-containing substrates delayed initial plant growth up to 45 DAE, but increased plant development after 75 DAE and improved plant performance and carrot yield measured at the harvest time (90 DAE).-
