Evaluación de la correlación entre porcentaje de raíces sanas y desarrollo vegetativo durante las fases fenológicas del cultivo de banano.

Abstract

In our province, banana production is usually affected by various phytosanitary complications that impact the leaves, fruit and roots, sometimes reducing weekly production; The roots of bananas and plantains absorb nutrients through their villi or absorbent hairs, which depend on water transport. This process requires energy and is very sensitive to oxygen deficiency in the soil, especially when there is excess water. The observations focused on how these factors can influence either the age of the plant, the growing conditions, and the phenological stage. This study analyzes the interaction of banana roots with the substrate and the rhizosphere, highlighting the importance of reactions with microorganisms and symbiosis with fungi and bacteria to optimize nutrient absorption, in each of the growth stages. This research was carried out on the Santa Inés farm, of the Faculty of Agricultural Sciences using the Williams clone, in an area of ​​2,400 m², the crop is modernized with drip irrigation, where we assess parameters such as root weight at a certain stage of the cultivar. and carrying out all the functions with specific techniques according to the period they were in, for the sample extraction we carried out the excavation with the specific conditions indicated by the laboratory which were 0.25x0.15x0.25 or 0.30x0.15x0.30 In this area, the previously washed roots will be taken and weighed, to later send these samples to the laboratory, which will detail the percentage of healthy and affected roots, the pathogen that affects in a certain phase or period. The results showed that there is a significant difference between the phenological phases in relation to the study variables. Verifying that the banana root system undergoes a different development in each phenological phase
