Abstract

An attempt was made to investigate the effect of different polluted soils on the mycorrhizal association, nodulation and subsequent growth of Acacia melanoxylon and Leucaena leucocephala tree species. Five industrial pollutant affected soils viz., Organic chemicals, pesticide, detergent, paper and neem seed oil cake were employed in this study and Palamuru University Campus soil used as a control. Among the five types of effluents, Adarsha paper Industries and Vidyadhari neem extract effluents exerted less negative effect. Corey organics and Rhyme organics factory effluents have shown maximum inhibitory effect, K. K. Detergent factory effluents exerted moderate inhibitory effect. Both agro forestry tree species were shown similar response towards AM colonization, nodulation and growth against five industrial effluents.

Key words: Mycorrhizae, pollutants, Acacia and Leucaena
