Relative efficacy of single and multiple inocula of arbuscular mycorrhizal fungi for kodo millet (Paspalum scrobiculatum L.)

A. Channabasava, H.C. Lakshman

Abstract


Experiments were conducted to understand the growth of Paspalum scrobiculatum L. (Kodo millet) in presence single and combined inocula of AM fungi under green house conditions. The single inoculum used was Glomus fasciculatum along with Gigaspora margirata and Sclerocystis dussi, G.  fasciculatum with Gigaspora margirata and Sclerocystis dussi were used as double inocula and the combination of all three AM fungi was used as triple inocula. The plants inoculated with these triple inocula brought significant increase in plant height and biomass production. The results further revealed that the experimental plants inoculated with triple inocula showed significant increase in the number of grains produced per plant, the dry weight of shoot and root and phosphorous uptake in shoot compared to dual and single inoculation. This increase in growth and biomass of the inoculated plants strongly depend on their ability to accesses minerals from the soil. The role of mycorrhizal fungi in improving plant growth was through improved uptake of nutrients, especially phosphorus. Therefore, the triple inoculation is better than the single and dual inoculation of AM fungi for better yield on the Paspalum scrobiculatum.
