title: Evaluation, grafting success and field establishment of cashew rootstock as influenced by VAM fungi.
abstract: Seven isolates of vesicular arbuscular mycorrhizal (VAM) fungi were isolated from cashew rhizosphere soil of different cashew growing regions of South India. These seven isolates along with two more VAM fungi namely Acaulospora laevis and Glomus mosseae, which were found to be better symbionts for cashew during our earlier study were used to study their effectiveness on the growth and nutrition of cashew rootstock Ullal-1. Four promising VAM fungi were selected based on this study. Rootstocks inoculated with these four fungi were evaluated for their vigour through grafting success, using Ullal-3 cashew variety as scion. Grafting success was more in rootstocks inoculated with A. laevis and one of local isolates Glomus etunicatum. Grafts with rootstock treated with G. etunicatum and A. laevis survived and performed better when planted in the field compared to the uninoculated and other VAM fungal treatments.
