| Objectives of this work were to determine the sample size (number of plants) to estimate the mean of slender leaf rattlebox (Crotalaria ochroleuca) traits and investigate the relations among traits. In an experimental area of 8 m × 20 m (160 m2), at 147 days after sowing, 110 plants were randomly selected. The following traits were evaluated for each plant: plant height, stem diameter, number of nodes, number of leaves, leaf fresh matter, stem fresh matter, shoot fresh matter, leaf dry matter, stem dry matter and shoot dry matter. Measures of central tendency, variability, skewness and kurtosis were calculated. Normality was verified using the Kolmogorov-Smirnov test and the sample size was calculated to estimate the mean of the traits, assuming estimation... |
