Corn (zea mays l.) growth as affected by soil compaction and arbuscular mycorrhizal fungi
2013
Miransari, M.
A two-year research work was performed under greenhouse conditions to evaluate: 1) the effects of soil compaction on corn growth, and 2) if using different species of mycorrhizal fungi under non-sterilized and sterilized conditions can alleviate the stress of soil compaction on corn growth. After sieving the field soil and sterilizing half of it using an autoclave, it was compacted in 2-kg pots. The soil was then planted with corn seeds and inoculated with different species of AM species including Glomus etunicatum, G. mosseae, and G. intraradices. While high levels of soil compaction decreased corn growth, AM inoculation significantly enhanced root and shoot growth and hence plant growth under compaction and G. etunicatum was the most efficient one. These results are important complementary to the previously little documented results regarding the effects of AM fungi on corn growth under compaction stress and are of agricultural and ecological significance.
