- Abstract
The purpose of this study was to evaluate the effect of different dosages of phosphate fertilizer to determine the optimal volume of containers through the Dickson Quality Index of four native species seedlings, in nursery. The experiment was conducted in a completely randomized design. The measured parameters were: height, stem diameter, dry weight of aerial and dry weight of root, 75 days after emergence to determine the Dickson Quality Index. The data was represented by mean and standard deviation. The Welch test and ANOVA were used to compare unpaired means. The significance level was 5% and the software used was SPSS for Windows version 17. Different P2O5 concentrations indicated that the optimal production container for the evaluated species is the dibble-tube of 120 cm³, promoting the highest Dickson Quality Indexes.
