Desarrollo del chamburo (Vasconcellea pubescens) durante los seis primeros meses de la etapa vegetativa con la aplicación de sustrato enriquecido, bajo cubierta plástica

Abstract

Ecuador is a country with great floristic diversity that is home to endemic and native species between the most interesting species native is chamburo (Vasconcellea pubescens A. DC.), it is a considerable crop to recover the agrobiodiversity of agroecosystems on farms, and is even considered a promising crop with high expectations of industrialization. However, there is not much information on the optimal conditions for their reproduction and development, that could condition the species to extinction situations. Therefore, the objective of this research is to evaluate the development of V. pubescens A. DC. during the first six months of the vegetative stage, using substrates enriched with rock dust mixed with bokashi, under plastic cover. With the application of a random block design with factorial arrangement (2x3) and a chemical treatment, the results are based on continuous data from observations of plant development (plant height, stem diameter, root biomass, number of leaves, survival of leaves, leaf area, chlorophyll content and aerial biomass) and the properties of the substrates used (chemical and physical properties of the soil: pH, electrical conductivity, apparent density, field capacity and organic matter content). It was observed that the treatments of the bocashi and their mixtures with rock dust were more effective, being the treatment 6 bocashi with 78 g of rock dust, the one that obtained the best results for V pubescens.
