Abstract

With the aim of evaluating the management ofgreen manures in the mycorrhized coffee seedling productionon Distric Nitisol soil, Sorghum vulgare, Crotalaria juncea,and Canavalia ensiformis were seeded and characterized, andafter 70 days they were added to the soil for obtaining differentsubstrates (SAV), in order to study seedling response to anefficient AMF strain inoculation, in a randomized completedesign with (5x2) factorial arrangement, besides includingtreatments of single soil and soil/earthworm humus (3/1).Inoculation effectiveness was further studied on the substratesmade up of earthworm humus added to incorporated sorghum(SAV), including treatments 3/1 and the check through a (x2)factorial arrangement. The greatest dry weight production andN, P, K extractions were achieved by sorghum, followed bycrotalaria. Green manures slightly increased native seedlingmycorrhization and there was a significant coffee response tomycorrhizal inoculation either with sorghum or crotalaria;however, to obtain healthy seedlings and an effectivemycorrhization, it was also necessary to add earthworm humusat the rate of 7/1 on the incorporated sorghum (SAV) andefficient AMF strain inoculation.
