Schizolobium parahyba, dasometric variables, seedling survival, weeds, sustainable natural regenerationAbstract
The study evaluated the initial growth of Schizolobium parahyba under different weed control techniques, both crown and parallel. A 2A × 3B completely randomized block design was used, where A represents the distribution of vegetative material (around the canopy and parallel to the planting lines) and B the canopy radius (50 cm, 75 cm and 100 cm). Twelve treatment plots and one control plot were established. Height, diameter, number of leaves and survival were measured from the second month onwards, with a periodicity of 30 days. Among the findings. Survival did not depend on the radius or distribution of the material, since the control plot did not show the lowest yield. It is noteworthy that weed control favored growth, being the treatment with 50 cm crowns and vegetative material around them the one that obtained the best results in all the variables analyzed.
