Field inoculation of maize with vesicular-arbuscular mycorrhizal fungi by using expanded clay as carrier material for mycorrhiza
1987
Baltruschat, H.
In 1985, different maize cultivars ('Forla', 'Blizzard', 'Limac') at two sites in Westphalia were inoculated with vesicular-arbuscular mycorrhizal fungi. As mycorrhiza-inoculum served spore-containing particles of expanded clay from mycorrhizal stock cultures of Glomus etunicatum. The size of the expanded clay particles was adjusted to the average particle size of commercial fertilizer (2-4 mm). The application of the expanded clay particles was performed with a combination of a pneumatic single corn sowing machine and an underfoot fertilization aggregate which was modified for test purposes. The application of mycorrhizal inoculu1352m directly into the seed row led both to a promotion of mycorrhizal infectivity and - in connection with P-underfoot fertilization - enhanced biomass production at the 3 to 5-leaf stage with each of the maize cultivars tested. The application of the mycorrhizal inoculum alongside of the seed row-analogous to underfoot fertilization - neither had a significant influence on percent infection nor biomass production of m
