摘要：Cotton production represents an important agricultural crop in Brazil. Therefore, studies associating soil physical attributes with fiber and seed cotton production are necessary. Accordingly, this work aimed to determine the influence of soil physical attributes: clay, sand, silt, microporosity, macroporosity, total porosity and density, in the harvested form of cotton. A canonical correlation analysis was carried out using data obtained from 193 soil samples that were collected in 100 plots with 13 cotton cultivars, between 63 and 136 days after emergence, distributed in 3 regions of the State of Mato Grosso, at altitudes of between 402 and 885m. The canonical correlation analysis explained 82.99% of the sample data variation. The soil physical attributes influenced in the cotton plant production, fiber yield and seed cotton production, in this sequence: (Silt = Microporosity) > (Clay = Macroporosity = Sand) >> microporosity, Total porosity > Density. The density, total porosity and macroporosity did not affect fiber production, respectively. In this regard, soil physical attributes alter the fiber quality.
