OROZCO HERNANDEZ, Luis Alberto et al. Effect of Glomus fasciculatum and its relationship with three organic fertilizers on two broad bean cultivars. Rev. Mex. Cienc. Agríc [online]. 2016, vol.7, n.6, pp.1423-1437. ISSN 2007-0934.

The interest of broad bean producers is to weigh between sustainability and economy; high production and quality could be obtained with arbuscular mycorrhizal fungi (HMA) and organic fertilizers. This work was established at the Experimental Field Ranch "San Lorenzo" located in the municipality of Metepec, State of Mexico. The main objective was to evaluate Glomus fasciculatum with vermicompost, manure and mushroom compost in 1, 2 and 3 t ha-1 and N60-P60-K30 applied in two broad bean cultivars. The 40 treatments were randomized in an experimental design in a randomized complete block with three replications, in split plot arrangement; both cultivars with and without mycorrhiza (C + M) were big plot and the type and amount of fertilizer the small plot (B). The experimental unit consisted of three rows of 4 x 0.80 m. The distance between plants was 0.40 m. Significant differences were detected for both factors and in their interaction in 19 of the 21 variables. When applying G. fasciculatum the cv. San Pedro (C1) expressed the highest average in NNF, AP, IV, NVP, PVP, PSL, P100 S, RG,% COL, LRz, NRs, NBs,% VES and %ARB. Chicken manure and mushroom compost with 3 t ha-1 favored a better phenotypic expression in most of the variables evaluated. C1 with 3 t ha-1 of chicken manure and HMA showed the best behavior for AP, IV, NVP, PSL, P100S, and RG (2.63 t ha-1). C1 with 3 t ha-1 of mushroom and mycorrhizal originated higher %COL (72.20%) and ARB (71.46%). cv. Santiago (C2) with 3 t ha-1 of chicken manure and HMA showed the highest PVP (124.10 g), NSL (32.63), PSL (62.40 g), RG (2.40 t ha-1),% ARB (73.30) and %hyphae (8440). The main components 1 and 2 explained 52.42% of original total variation.
