Evaluación de la calidad de planta de palmito (Bactris gasipaes kunth) con dos sustratos y dos microorganismos a nivel de vivero

Abstract

This investigation aimed to evaluate the quality of peach palm plant Bactris gasipaes KUNTH with two substrates and two microorganisms at nursery level, for which pre-germinated seed was used, the producer substrate is made in the farm, place in which the trial was installed, for the second substrate soil was used to sow. The microorganisms used were Trichoderma harzianum and Trichoderma viride. For the statistical analysis, a completely randomised bifactorial design was used to evaluate plant height, stem diameter, number of leaves, root length, fresh and dry weight of the leaf area, fresh and dry weight of the root and leaf colour. The Dickson index was used to determine plant quality as well as and economic cost-benefit analysis was carried out. The results established that the producer substrate was the best substrate with the greatest plant height, number of leaves and stem diameter. Trichoderma harzianum was the most effective treatment, with the highest values for plant height, number of leaves, stem diameter and Dickson's index. The treatment that corresponds to the substrate producer and Trichoderma harzianum on the basis of the economic analysis turns out to be the most profitable since it manages to obtain a benefit cost of $1.86, so it was the best treatment. It is recommended to carry out an analysis of the substrate to determine the nutrient content that it can provide to the peach palm plants at nursery level.
