Abstract :

In this study, the effects of symbiosis between plant roots and mycorrhizal fungi which is often present under natural conditions in the environment on corn yield and quality criteria were investigated. Experiments were conducted by using a mixture (trade name‘Endo-Roots”) involving Arbuscular Mycorrhizal Fungi (AMF) which have significant importance in agricultural practices. Routine fertilization which is one of the vital conditions in terms of a successful mycorrhizal colonization which do not cause phosphorus stress was applied by considering field conditions, as well. Control and different dose mycorrhizal applications did not cause a significant difference in green mass yield of corn plants, while grain yield was positively influenced by mycorrhizal application. A positive increase was also observed in parameters concerning corn cob yield due to mycorrhizal symbiosis. Fungal colonization which was found to be 26-30 % in the roots by ‘Endo-Roots1” applications, suggests that this ratio would even increase in the case of plants being under phosphorus deficiency. In case of shortage of plant nutrients, AMF is believed to have great contribution to plant yield and quality criteria and the resistance to the plant diseases.
