Efecto de la inoculación multiespecie con Paenibacillus polymyxa y micorrizas frente al manejo restrictivo de nutrientes sobre la sanidad y el rendimiento en trigo (Triticum aestivum L.)

Wheat cultivation (Triticum aestivum L.) is essential for food security in various regions of the world, including the Ecuadorian highlands, where it faces significant challenges such as diseases, pests, and low fertilization levels, which impact both yield and quality. This study aimed to evaluate the effect of multi-species inoculation with Paenibacillus polymyxa and mycorrhizae, along with different fertilization levels, on the health and yield of wheat in Bolívar province. A randomized complete block design (RCBD) with a 2 × 5 factorial arrangement and three replications was used. The results showed that inoculation with Paenibacillus polymyxa and mycorrhizae, combined with proper nutrient management, significantly improved agronomic variables such as seed emergence, root density, and plant height. Treatments T6 and T8, which included inoculation and nutrient levels of 100 % and 50 %, respectively, showed the best results. Treatment T6 stood out in particular, achieving a yield of 5,381.29 kg ha⁻¹ and reducing the severity of diseases like fusarium and rust. However, T6 involved higher variable costs, affecting its profitability, although it proved to be the most effective option in terms of productivity and crop quality. On the other hand, treatment T5, which did not include inoculation and used 0 % fertilization, was the most cost-effective, despite its lower yield. In conclusion, multi-species inoculation, combined with proper nutrient management, proved to be a promising strategy for improving wheat yield and health, although its economic viability is influenced by high production costs.
