Native AMF (isolated from the Chihuahuan desert) and commercial AMF were evaluated in a greenhouse to determine their efficacy in the alleviation of salinity stress on the growth and yield of Capsicum annuum (chili pepper) ‘Jalapeño M’ and ‘NuMex 6-4’. A factorial experiment design with AMF [native AMF (AMF1), commercial AMF (AMF2), and no AMF] and salinity [electrical conductivity (EC) of 1.4, 4.0, or 8.0 dS·m-1] with nine plants per treatment was employed. Chili pepper seedlings were transplanted in 7.6-L pots containing Metro-Mix 360 growing medium. While transplanting, twenty-seven seedlings were inoculated with AMF1 or AMF2, 40,000 spores per plant. To facilitate root colonization, Long Ashton solution with 44 mg·L-1 KH2PO4 was applied weekly to control plants, whereas Long Ashton solution with 22 mg·L-1 KH2PO4 solution to inoculated plants. Salinity treatments were initiated 17 days after AMF inoculation and applied weekly for a total of seven times. AMFs had no effect in the leaf area and dry weight of both chili pepper cultivars, but salinity at EC of 8 dS·m-1 negatively affected the leaf area and dry weight. Despite the reduction in exogenous phosphorous application, AMF1 inoculated ‘Jalapeño M’ and ‘NuMex 6-4’ plants had similar number of fruit compared to non-inoculated plants. AMF1 inoculated ‘Jalapeño M’ plants also had similar fruit fresh weight to that of non-inoculated plants.
