ABSTRACT:

A glass house experiment was conducted to study the effect of different AM symbionts on the growth and oil content of African marigold. Among the six arbuscular mycorrhizal (AM) cultures used, Glomus fasciculatum treated plants had the maximum plant height, number of leaves, dry matter yield and oil content. G. fasciculatum inoculation also resulted in increased P nutrition and mycorrhizal colonization compared to the rest of the treatments. This suggests that G. fasciculatum could be used as the best AM inoculant for enhancing the growth and yield of marigold.
