Abstract
Objective: To know the effect of controlled release fertilizers on the growth and development components of Tabebuia rosea (Bertol.)
Design/methodology/approach: In this research, a randomized block design with seven treatments and 50 replications was used. Three treatments will consist of substrate with different mixtures of Controlled Release Fertilizers (CRF) at three concentrations each of 4, 5 and 6 kg m-3 plus a Control (without fertilization).
Results: The use of controlled release fertilizers such as Multicote™ Agri 8 and Basacote® Plus 9M demonstrated greater growth and development in macuilis seedlings on the components of plant height, basal stem diameter, aerial biomass, root biomass among others, of the seven treatments presented in this research, the concentrations at 5 and 6 kg m-3 proved to be the best nutritional alternative, which will result in a higher survival rate in the field.
Limitations on study/implications: Due to the loss of undisturbed specimens, it is becoming increasingly difficult to find trees with seed production capabilities.
Findings/conclusions: Multicote™ Agri 8 in concentrations of 5 and 6 kg m-3 is the best nutritional alternative for optimal growth and development. As far as I know, it is essential for reforestation in urban and rural areas of the region. In addition, for its floral beauty that is part of the culture of the state.
