Evaluación del efecto de la aplicación de vermicompost enriquecido con bacterias promotoras del crecimiento vegetal y hongos micorrízicos en el desarrollo del maíz (Zea mays)

Abstract

Abstract:The rapid population growth has increased the demand for food worldwide, which is why intensive production systems characterized by the indiscriminate use of natural resources have been implemented, affecting the structure of the soil and biological diversity. The objective of the study was to evaluate the effect of adding vermicompost enriched with microorganisms on the development of corn. The research was carried out in the Ciudad Alegría neighborhood of the city of Loja in an area of 8 square meters. Five treatments were established corresponding to the use of plant growth promoting bacteria and arbuscular mycorrhizal fungi with a constant dose of vermicompost for the treatments. The treatments that presented significant positive differences were: vermicompost + HMA + PGPR (T3), vermicompost + PGPR (T4) and conventional (T5). Regarding the height of the plants at 60 DDS, the T5 obtained 68.55 ± 3.91 a compared to the control with 44.40 ± 1.77 c, representing a significant statistical difference. Regarding the diameter at 60 DDS, the T5 reflects values 5.23 ± 0.13 a, statistically significant to the control that shows 3.53 ± 0.15 b.
