Efecto de la inoculación con hongos micorrízicos en el rendimiento de avena forrajera

Objective: The objective of the present study was to evaluate the effect of inoculation with two species of mycorrhizal fungi on the yield of forage oats.Design/methodology/approach: The method of pelletization and seed coating was used; The sowing went to volley. A completely randomized design with factorial arrangement (233) was used as factors: the two varieties, the HMA Glomus cubense and Glomus fasciculatum with a control and fertilization at 50% and 100% with a control with four repetitions.Results: The Chihuahua variety obtained a better yield, leaf stem ratio, leaf area index, number of leaves, leaf death, stem density and leaf death (2.50); in the other variables they were statistically equal. The Glomus cubense species was superior to Glomus fasciculatum in the yield variables (6.92 t DM ha1) and in the death of leaves (4.68), but in the leaf area index (135.02), Glomus fasciculatum exceeded Glomus cubense.Limitations of the study/implications: yield in fodder production, producers apply high amounts of chemical fertilizers, whose excessive use negatively affects the soil resource.Findings/conclusions: The Chihuahua variety has better behavior and Glomus cubense exceeds Glomus fascicucatum in performance
