Vesicular-arbuscular Mycorrhizal Mediated Effect on Plant Growth in a Saline-alkali Soil in Relation to Various Amendments

Abstract

Growth performance of different plant species raised in saline-alkali soil was monitored. The growth got improved by the amendments, which decreased the saline-alkali soil stress conditions like pH and salt concentration. The effect of amendments on plant growth improvement was independent of plant species. Inoculation of Glomus sp. RR1 (an indigenous mycorrhizal species isolated from the saline-alkali soil) in plants enhanced their performance when subjected to various conventional amendments that are given to improve plant growth under saline-alkali stress conditions. Maximum plant growth was observed when Glomus sp. RR1 inoculated plants were grown in gypsum amended saline-alkali soil in most of the case.
