“…Los mismo ocurre con la altura de mazorca y área foliar, por el efecto las bacterias en promover el crecimiento, ya que contribuyen a incrementar la absorción de N a comparación del testigo, en muchos casos este aumento va del 21 al 42% (Caviedes-Cepeda et al, 2022). El área foliar tiene relación con el rendimiento ya que a mayor superficie foliar existe mayor capacidad de producción de materia de reserva y esta vinculado a los contenidos de nitrógeno que es el elemento juega un papel importante en el rendimiento, así como otros nutrimentos fósforo, potasio principalmente (Gutiérrez-Peña et al, 2022). En este experimento se encontró mayor significancia en la fuente de variación de cultivar correspondiente a la variedad Marginal 28T, se puede afirmar la influencia de la genética como su ventaja por ser una variedad de polinización libre.…”

Background: The utilization of organic fertilizers is put forward as an effective approach to address soil degradation and enhance crop yields. Objective: To assess the impact of applying microbial consortia, in combination with fermented liquid fertilizer (biol), on maize grain production, with a focus on fostering sustainable family farming in dry tropical conditions. Methodology: A randomized complete block design with three blocks and divided plots was employed, with the main plots featuring various maize cultivars, while the subplots consisted of four bioferments and a control treatment. The bioferments included Microbial Consortium (CM), BIOL+CM, and BIOL+EM-1, compared to the commercial product Efficient Microorganisms (EM-1) and a control with no application. Parameters such as days to male and female flowering, plant and ear height, leaf area, grain diameter, and yield, along with the physical and chemical soil characteristics, were evaluated following the bioferment application. Results: The application of BIOL+CM to the Marginal 28T variety resulted in increased plant height (164.17 cm) and cob size (65.83 cm), as well as a larger leaf area (361.17 cm²). It also enhanced the grain yield of the Marginal 28T variety (3.42 tꞏha-1) and the HS-1 hybrid (3.02 tꞏha-1). Implications: The combined use of locally-sourced microbial consortia and Biol significantly improves the agronomic performance of hard yellow corn and aids in maintaining the soil's physical and chemical conditions, thereby promoting its enhancement. Conclusion: The Marginal 28T variety and the HS-1 hybrid exhibited a favorable response to the application of microbial consortia, particularly BIOL+CM, making it a viable option for family farming in dry tropical conditions.

This study assessed the effects of different nitrogen doses on maize crops, with and without the inoculation of Azospirillum brasilense. The experiment was carried out during the 2020/2021 harvest season in the administrative department of Concepción, district of Horqueta, Paraguay, at the coordinates of 23°14'31.7" S and 56°53'05.9" W. The experiment followed a randomized complete block design (RCBD) arranged in a factorial design (4 X 2). Factor A included nitrogen doses (0, 40, 80, and 120 kg ha-1), while factor B corresponded to the bacterial inoculation (with and without A. brasilense). The experiment was performed in three replications; each experimental unit (EU) was 22.5 m2. The study evaluated the following characteristics: plant height, cob insertion height, cob length and diameter, weight of 1000 kernels, and kernel yield. The data were analyzed using analysis of variance (ANOVA), and the averages were compared using Tukey's test at a 5% probability of error. Regression analysis was also carried out during the study. The experiment results demonstrated that increased nitrogen levels positively affected the measured characteristics, fitting a quadratic model, except for cob insertion height. Inoculation with A. brasilense significantly increased corn growth and productivity. The interaction of both factors produced a significant increase in cob length. Based on the experiment results, applying 104.30 kg ha-1 of N in combination with A. brasilense inoculation is recommended for improved maize production.
