Effect of endomycorrhiza (Glomus intrarradices) and organic matter on the growth of cactus pear (Opuntia albicarpa) in two soil types

Most of the farmers who grow cactus pear (Opuntia albicarpa) use manure as a fertilizer. This practice increases problems pests. The endomycorrhiza (Glomus intraradices) is almost unknown to farmers. Therefore, objective this research was study effect application with organic matter (OM) and inoculation in pear.
 conducted under greenhouse conditions at Montecillo Campus Postgraduate College, Mexico. Two types soil from San Luis Potosí, Mexico were used, one reddish coloration (xerosol) another gray (lithosol).
 results show that there significant differences (p ≤ 0.05) all variables by endomycorrhiza, majority those OM. Both mycorrhiza OM, vermicompost, promoted greater growth stem root. soils used did not affect plants.
 can be useful improve mineral nutrition, thus increase yields plantations. In addition, these fungi yields, help reduce production costs. 50 t ha-1 vermicompost better alternative add nutrients OM crop.
