Evaluation and first-year field testing of efficient vesicular arbuscular mycorrhizal fungi for inoculation of wetland rice seedlings

Grain yields of the rice cultivar Prakash were improved upon inoculation with Glomus intraradices and G. fasciculatum, by 11% and 8%, respectively, compared with an uninoculated control. The results indicate that the amount of phosphate fertilizer usually applied to rice may be decreased by 50%, without affecting yield, if G. intraradices is inoculated.The authors are with the Department of Agricultural Microbiology, University of Agricultural Sciences, GKVK Campus, Bangalore 560 065, India. ing author.
