Abstract

Response of wheal plants to VA-mycorrhizal inoculation in presence or
absence of 1% olive oil waste water (O.O.WW.) or olive cake (0. Cake) as an
organi<: fertilizers was investigated in a pOI experiment. The results shOWed that
inoculation with VAM improved aU growth pararneters at 60 and 120 days arter
planting e.g. plant height. number of tillers, dry weight of shoots and roots compared
10 those amended with olive wastes but not inoculated. Regarding to straw and seed
yield of wheal plants. the maximum straw and seed yield was obtained by addition of
O.OW.W. at a rate 01 1% combined with inoculation with VA-mycorrhiza. Nitrogen
and phosphorus contents of shoots, roots, straw and seed yield were also
significantly increased due to VAM inoculation. Conceming the effect of VAM
inoculation in presence of olive wastes on VAM rate of infection and spore densities.
data revealed that there was a signiftcant improvement in VAM COlonization and
spore density, compared to which noIlnoculaled with VA-mycorrhizae. This indicated
that VAM inoculation could reduce the loxicity caused by olive wastes. Generally from
the abovemented results. it can be concluded that inoculation of ....neat With VAM
considered a biological trial to reduce the Inhibition effect of olive wastes as In
organic fertilizers.
