Substrates and Container Size on Quality of Peltophorum dubium Seedlings
Abstract This study aims to evaluate the effect of substrates and container content on growth and quality of Peltophorum dubium seedlings. The design was completely randomized in a factorial arrangement (2 × 9), with two containers sizes (125 cm3 and 280 cm3) and nine substrates formulated from the mixture of subsoil (S), vermicompost (V) and commercial substrate (CS), in the following proportions (v:v): S100, V100, CS100, S75 + V25, S50 + V50, S25 + V75, CS75 + V25, CS50 + V50 and CS25 + V75, with nine replicates. We assessed seedling height, stem diameter, root and shoot dry matter, height/shoot dry matter ratio; Dickson quality index; and percentages of nitrogen, phosphorous and potassium in the shoot. The use of the 125 cm3 dibble tube containing 100% vermicompost allowed for higher quality of Peltophorum dubium seedlings.
