Abstract
Arbuscularmycorrhizae fungi (AMF) benefit to plants growth is not still to demonstrate. However, little is known about the effects of exogenous AMF (from temperate soil) on cocoa (Theobroma cacao) that plays an important role in the economic prosperity of Côte d’Ivoire. A greenhouse experiment was conducted to assess the effectiveness of AMF from temperate soil (Rhizophagusirregularis named exogenous inoculum) and Ivoirian soil (complex of strain found in soil named natives inoculums) on growth of cocoa plants during ten months. The experiment was a single factor experiment arranged in a completely randomized block design, with type of inoculum as a factor with twenty replications. Roots of all inoculated seedlings were colonized and the best frequency was observed with exogenous AMF. Analysis of growth parameters showed a significant difference between treatments for variables "Area", "Diameter", "Height", and fresh and dry biomass production. The best results were obtained with natives inoculum. However, exogenous inoculum showed much better results compared to the control. Indeed, Maximum plant diameter, height and leaf area of 14.49 mm, 1083.7 mm and 94.24 cm2 respectively were obtained from seedlings inoculated with native's inoculum. The highest total fresh and dry biomass production (202.1 g and 53.86 g) was also recorded from seedlings inoculated with natives inoculum.
