Vermicompost in substrate composition for seedlings production of Schinus terebinthifolius
The objective of the present study was to analyze the effect of addition of vermicompost to the substrate of Schinus terebinthifolius seedlings. We tested five treatments composed by the addition of vermicompost on Carolina Soil® substrate (T1: 100% Carolina Soil® (CS); T2: 75% CS and 25% vermicompost (VC); T3: 50% CS and 50% CV; T4: 25% CS and 75% CV and T5: 100% CV). The morphophysiological characteristics evaluated at 150 days after seedling emergence were: stem diameter (d), shoot height (h), photosynthetic pigment content, shoot dry mass (SDM), roots dry mass (RDM), total dry mass (DMtotal), Dickson quality index, h/d ratio and SDM/RDM ratio. Data were submitted to analysis of variance, regression analysis and Pearson correlation. The correlation and the growth response curve for the seedlings, due to the different proportions of vermicompost and commercial substrate showed that the additions of 50 or 75% of vermicompost were the ones that favored the growth of S. terebinthifolius seedlings.
