The symbiotic activity that mycorrhizal fungi present may constitute a major biotechnological component to increase horticultural productivity. Among the benefits of the AMF-host plant symbiosis, is growth promotion and greater mineral nutrition of the plant. The horticultural production in greenhouse has had an increasing expansion in Mexico, because it has advantages, not only in consumer demand but by the high productivity generated. However, there are multiple factors that proceed from different agricultural practices that express in quality of production. Nutrition and fruit quality of pepper (cv. 'Valeria') was evaluated, by effect of inoculation with arbuscular mycorrhizal fungi (AMF) Rhizofagus intraradices, in greenhouse. The crop was handled with a fertigation system and HMA inoculation was in transplantation. The inoculated plants showed an increase in chlorophyll index, leaf contents of N, P, Fe and Zn, and mycorrhizal colonization, compared with non-inoculated plants. Also showed differences in fruit quality; by size, the fruits from non-inoculated plants reached grade 2, while the AMF reached level 1, with a weight gain of 30%. Inoculation with the AMF represents a biotech management that can be added within the horticultural production practices in greenhouse.
