Efecto de bioestimulantes sobre propiedades del suelo, clorofila y salud radical del banano

Abstract

Introduction: The banana (Musa spp.) production stimulates Ecuadorian economy; it represents one of the main export items. There are limitations in banana production related to the soil. Therefore, the physical and chemical properties of the soil are fundamental in production. The vegetative development of a plant depends on root health. In such a way that biostimulant applications (humic acids and rooters) and agricultural practices (aeration and soil turning with tools) have been developed. Objective: To evaluate the effect of different root stimulation programs for banana cultivation, analyzing the physical and chemical soil properties, foliar chlorophyll level and root health. Materials and methods: The experiment was carried out in the "Adrianita" farm located in the canton of El Guabo, in the province of El Oro, Ecuador. A completely randomized block design (DBCA) was used, with six treatments and four replications. The variables evaluated were: apparent density (DA), real density (DR), percentage of porosity (PP), percentage of volumetric humidity (HV), percentage of carbon (PC), organic matter (OM), pH, electrical conductivity (EC); chlorophyll levels (SPAD); total root mass (MR), percentage of functional roots (PRF), and percentage of non-functional roots (PRnF). Results and Conclusion: The results revealed that soil depth is correlated with the physical and chemical parameters of the soil. There is also much influence of biotic and abiotic factors on the data obtained from surface soil samples. SPAD and PRF increased in plants that received turning treatment with a tool.
