FLORES-JUAREZ, Diana Jazmín et al. Inoculation of forage oats with arbuscular mycorrhizal fungi. Rev. Mex. Cienc. Agríc [online]. 2020, vol.11, n.spe24, pp.191-199.  Epub 07-Maio-2021. ISSN 2007-0934.  https://doi.org/10.29312/remexca.v0i24.2369.

Soil deterioration has limited the yield and production of forage species. Arbuscular mycorrhizal fungi (AMF) aid in the effective absorption of minerals from the soil. The objective was to evaluate the growth relationship of forage oats with the inoculation of arbuscular mycorrhizal fungi. The experiment was carried out in a greenhouse of the Technological Institute of the Valley of Oaxaca, a soil sampling and a pedological analysis were carried out. The substrate was a mixture of soil and sand (2:1), autoclaved, in two stages. Two commercial inoculants were used, to which a direct spore count was performed. The variety of oats used was Chihuahua. Inoculation was carried out by direct sowing, the dose was 5 g by inoculating an oat seed in individual pots. A completely randomized design with 11 treatments and four repetitions was used. The variables studied were plant height, leaf width, leaf length, stem diameter, leaf-to-stem-inflorescence ratio, yield and leaf area index. Normality tests, an analysis of variance and a Duncan mean test were performed. The variable height (26.5 and 25.9 cm) and the yield (8.2 and 6.8 t DM ha-1) with inoculation of Glomus cubense and Glomus fasciculatum showed a significant statistical difference. It is concluded that there is an effect on growth and yield with inoculation of arbuscular mycorrhizal fungi.
