الملخص

Pot investigations were carriedout to study the effects of vesicular-arbuscular mycorrhizal (VAM) fungus Glomu sp and root-knot nematode Meloidogyne incognita on tomato (Lycopersicon esculentum) Nill plants.Shoots and roots dry weights and phosphorus content of tomato plants were significantly increased and decreased by Glomus sp. and Meloidogyne incognita, respectively. Nematode infection and damage were significantly reduced by mycorrhizal inoculation, whereas mycorrhizal infection percentage was not affected by nematodes. The effectiveness of Glomu sp. in reducing nematode damage was more pronounced when mycorrhizal inoculation preceded nematode. Application of high phosphorus doses although significantly improved plant growth, it reduced mycorrhizal infection percentages. Addition of nematicide Nemacur significantly reduced nematode infection (number of galls) but, it did not affect mycorrhizal colonization of roots. The VAM fungus Glomus sp significantly reduced nematode damage in sterilized silt and clay soil as well as unsterilized clay soil. The results indicate that the VAM fungi could be used as a biofertilizer for tomato and a biocontrol agent against root-knot nematodes.
