Effects of different organic substrates in the production of Caesalpinea violacea seedlings in tubes

Abstract

The present study was developed at the Center for the Study of Agricultural and Forestry Technology, belonging to the University of Guantánamo, carried out with seedlings of Caesalpinea violacea (Mill.) Standl. Its objective was to evaluate the effect of different organic substrates in the production of these species in tubes. The substrates were made from organic compounds such as: worm humus, coconut fiber and composted Pinus cubensis sawdust. The experiment was established with a completely randomized design, consisted of four treatments. The parameters and morphological indexes of seedlings were determined. For the treatment four composed were used: worm humus (30%), coconut fiber (60%), composted pinus cubensis sawdust (10%) and the mycorrhizal strain Glomus cubense (10g). The specie showed a better response to the values ​​reached in the different morphological parameters and indexes due to the application of Glomus cubense mycorrhiza and a higher percentage of coconut fiber.
