Abstract
El dióxido de carbono es uno de los principales gases causantes del cambio climático. Este estudio evaluó el efecto de la inoculación con Azospirillum brasilense en el secuestro de carbono y rendimiento de Zea mays bajo condiciones de campo en Acobamba-Huancavelica. Se aplicó un diseño experimental de bloques completamente al azar con cuatro tratamientos (0, 16, 32 y 64 g de A. brasilense por kg de semilla) y cuatro repeticiones en distintos ambientes. Se observaron diferencias estadísticamente significativas (p<0.05) en peso de carbono, altura, peso seco, peso fresco y rendimiento de grano. La inoculación con 64 g de A. brasilense por kg de semilla aumentó el secuestro de carbono en 8.15% y el rendimiento de grano en 28.12%. Estos resultados demuestran la afinidad del maíz con esta bacteria promotora del crecimiento vegetal y su potencial como alternativa sostenible para mitigar el cambio climático.
Carbon dioxide is one of the main gases responsible for climate change. This study evaluated the effect of Azospirillum brasilense inoculation on carbon sequestration and Zea mays yield under field conditions in Acobamba-Huancavelica. A randomized complete block design with four treatments (0, 16, 32, and 64 g of A. brasilense per kg of seed) and four replications in different environments was applied. Statistically significant differences (p<0.05) were observed in carbon weight, height, dry weight, fresh weight, and grain yield. Inoculation with 64 g of A. brasilense per kg of seed increased carbon sequestration by 8.15% and grain yield by 28.12%. These results demonstrate the affinity between maize and this plant growth-promoting bacterium and its potential as a sustainable alternative to mitigate climate change.
