Resumo: The objective of this work was to statistically characterize variables such as wheels slip, theoretical and effective field capacity of a planter in direct (DS) and conventional sowing (CS) systems, based on the verification of the adjustment of a series of data to a statistical distribution, aiming for the best form of representation and values be adopted so that these variables be used in agricultural practices operations. The experiment in CS was done with a speed of 1.5 m s-1 with 190 repetitions, and the experiment in DS was done with 1.8 m s-1 and 58 repetitions. It was concluded that differing values were not detected, and the variables in study can be represented by the function density of normal probability (Gaussian distribution), and the variables can be used for its representations.

O experimento na SC foi realizado com velocidade de 1,5 m s-1, com 190 repetições, durante a semeadura de milho em solo classificado como Cambissolo; o experimento na SD, com 1,8 m s-1 e 58 repetições, durante a semeadura de sorgo em solo classificado como Latossolo Vermelho-Amarelo. Concluiu-se que não foram detectados valores discrepantes e que as variáveis em estudo podem ser representadas pela função densidade de probabilidade normal (Distribuição de Gauss), podendo ser utilizados parâmetros para suas representações.Universidade Estadual de Maringá2009-08-28info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttp://www.periodicos.uem.br/ojs/index.php/ActaSciAgron/article/view/95110.4025/actasciagron.v31i4.951Acta Scientiarum.
