Effect of different substrates in Pentaclethra macroloba (Willd) Kuntze seedling growth

The study was developed with the objective of evaluating the effect of four substrates on the initial growth of P. macroloba plants grown in a nursery. Four combinations of substrates made from mixtures of horse manure and coconut fiber were tested to determine which one was feasible to achieve better plant quality with the use of tube technology. The morphological variables measured were: height, root neck diameter, number of leaves, dry biomass, as well as attributes of the root system. From these values, the morphological indices were calculated: Slimness, PSA/PSR Ratio and Dickson's Quality Index. The results obtained demonstrated that there was a differentiated effect on the growth of the plants depending on the substrate in which they were grown. Therefore, it is inferred that this substrate improves the initial growth of this species.
