The impacts of three levels of biochar (1 , 3 , 5)% on Arbuscular Mycorrhiza (AM) fungi Glomus mosseae activity was tested , On the other hand the effect of interaction between biochar and AM fungi on some growth parameters of sweet corn plant which growth under greenhouse conditions was studied .the results showed positive effects of biochar on AM fungi activity , The plant which treated with 5 % of biochar give highest increased in the percentage of mycorrhiza colonization and mycorrhizal root weight which were (96.67 % , 122.93 gm) Respectively, while the treatment with 3% of biochar recorded highest increased in spores number that (1980) spores , and there was no significant increased in mycorrhizal dependency . as well as the results showed positive effect of interaction between biochar and AM fungi on growth of sweet corn plant , the treatment of 3% of biochar + AM fungi recorded significant increased in plant height , fresh and dry weight of shoot , leaf area , fresh and dry weight of root which were (80.76 cm , 20.36 gm , 4.136 gm , 150.74 cm2 , 12.603 gm and 1.28 gm ) Respectively , for root length the treatment with 1% of biochar + AM fungi showed highest increased which was (54.93) cm . The result showed a negative effect of increased biochar level on sweet corn plants growth , but AM fungi activity was not affected.
