Crescimento de mudas e produçao do cafeeiro sob influencia de fungos micorrízicos e superfosfato
The effects of vesicular-arbuscular mycorrhiza fungal inoculation on initial growth, survival and yield of coffee plants (Coffea arabica L.) were studied from 1986 to 1991. Pre-colonization of seedlings with a multiple inoculum of Glomus clarum and Gigaspora margarita or with a mixture of indigenous fungi previously isolated from coffee fields, increased seedling growth and phosphorus uptake and also enhanced their survival and yield when they were transplanted into field. Fungal inoculation enhanced coffee bean yield by an average of 74 per cent over non-inoculated controls when superphosphate was added at transplanting. The mean productivity increase for the first three years of production was 420 kg/ha/year. This represents an additional net income estimated in US 400.00/ha/year and indicates the importance of the vesicular-arbuscular mycorrhizal fungi to coffee crop in low fertility soils.
