In the field, it is recommended that before the species are planted directly in the field, they should be grown in a nursery to observe their behavior in the initial growth stage.
▶ In such a way that the plants that are taken to the field are those that are more vigorous to face the affectations caused by biotic and abiotic stresses.

Even though in many cases the production costs for the subsequent establishment and exploitation of the species increase in the nursery, it is also noted that the plants have great versatility: erosion control, reforestation, production of wood and its derivatives, shade tree, organic fertilizer and livestock feed.
The work developed in the field is important because some of the variables studied are related to each other, and this will allow comparisons to be made with the results at the nursery level.
Field research is important for our work since the variables studied coincide with one of our objectives of determining the influence of the product on the seedlings in their growth stage.
