Abstract: The effect of Glomus fasciculatum inoculation on the growth and yield of tomato (Solanum lycopersicum L.) in a Meloidogyne incognita infested soil was investigated in a pot experiment. G. fasciculatum greatly enhanced the growth and yield of tomato in both non-nematode and nematode infested soils. Growth was greatly impeded to the point of no flowering or fruiting in non-mycorrhizal nematode infested soil treatments. While the adverse effect of nematode to the growth of tomato can be attributed to impaired transport of water and nutrients, the enhanced growth in mycorrhizal plants was associated with increased water and nutrient uptake, resulting improved growth which must have conferred more vigour on them to reduce the pathogens' effect.
