Effects of Arbuscular Mycorrhizal Fungi on the production of tomato in Togo
A field study was conducted to assess the effectiveness of the Arbuscular Mycorrhizal Fungus (AMF) Glomus sp. on the plant growth, the flowering and the fruit yield of tomato (Lycopersicon esculentum, Mill.). Thus, 4 strains of Glomus sp. (M233, M353, B3 and Gd) were tested in comparison with NPK fertilizer on 3 tomato varieties ICRIXINA, TROPIMECH and PETO76, using a complete randomized block design with three replications. The results revealed that 84 days after transplanting (DAT), the rate of root colonization by the fungus did not exceed 25%, and the plant height was not affected by AMF inoculation, whereas M353 induced late flowering on ICRIXINA at 69 DAT and PETO76 at 74 DAT. Also the four AMF strains induced similar fruit yields as that of NPK for each of the 3 tomato varieties used. However, the response of tomato plants to AMF varied with the varieties.
