Evaluar el efecto de tres sustratos para la propagación asexual de Guadua angustifolia en el Vivero Agroforestal Timbre, cantón Esmeraldas, parroquia San Mateo.

Abstract

The general objective of this study was to evaluate three substrates effects for the asexual propagation of Guadua angustifolia in the Timbre Agroforestry Nursery, San Mateo Parish, Canton Esmeralda, San Mateo Parish, Esmeralda Canton, where the measurement, cleaning of the site, subsequent mixing of the substrates and planting of the experimental material were carried out. A randomized complete block design (RCBD) was used. Factor A corresponded to three types of substrates: T1 Control: Agricultural soil, T2: Agricultural soil + sand +, T3: Agricultural soil + coconut fiber + river silt, and T4: Agricultural soil + sand + coconut fiber. The factor B propagation methods: seedling and layering. The variables analyzed were: height, diameter at collar height, number of leaves, number of shoots in an evaluation period of 20, 40 and 60 days, the different evaluation periods allowed us to determine the best substrate for the asexual propagation of Guadua angustifolia. The seedling growth percentage, the growth of Guadua angustifolia seedlings per treatment and the survival of our treatment and our vegetative material. As results we have that the substrate that responded best during the evaluation period was T1: Control: Agricultural soil and T4: Agricultural soil. agricultural soil and T4: Agricultural soil + sand + coconut fiber, with lower data records. The method applied to the different treatments was the propagation method, however, the propagation method by layering after 60 days of evaluation recorded higher data in the different treatments. Layering method is recommended for the asexual propagation of Guadua angustifolia because it is the one that has shown the highest and growth throughout the study period in the area, given that its reproductive capacity is accelerated, layering method, is recommended to perform the evaluations after 60 days because the process is slower, and requires longer times to have better results.
