Efecto de fertilización mixta en cultivo de maíz (Zea mays L.), en Tehuacán Puebla, México

The objective of this research was to evaluate the effect of mixed fertilization on maize cultivation, considering the application of Glomus intraradices and Azospirillum brasilense inoculated into the seeds of the native white Tehuacanero maize as biological fertilization. Chemical fertilization was also applied using the 90-90-46 formula, with urea, triple superphosphate, and potassium chloride as nutrient sources. The experimental design used was a randomized complete block design, evaluating 9 treatments with 4 replications. The treatment results showed a significant effect (p < 0.027), where treatments with mycorrhizae, Azospirillum, or their combinations had a positive impact on grain yield compared to the control treatment, which received neither fertilization nor inoculation. These findings suggest that the use of microorganisms can reduce dependence on chemical fertilizers, contributing to more sustainable and environmentally friendly agricultural practices.
