Obtaining seedlings of Anacardium occidentale L with the use of bioproducts to rehabilitate areas degraded by mining

Abstract

With the objective of evaluating the effect of different doses of Vigortem® and cta-Humus bioproducts in obtaining Anacardium occidentale seedlings for the rehabilitation of areas degraded by mining in Cedrones Baracoa. A test was carried out in nursery areas with the direct application to the seeds before sowing and 15 days after Vigortem® and one application of CTA-Humus. Height, stem diameter, number of leaves, fresh mass and dry mass, and growth indices were evaluated. From the data obtained, an analysis of variance was performed, for a randomized design. Duncan's Multiple Range Comparison Test was used for 95% to separate the means. It was obtained that the doses of 6 L. ha-1 of Vigortem® combined with CTA-Humus offer the most significant values in the growth and development of the Anacardium occidentale seedling under nursery conditions.
