Abstract

 

Mangifera indica showed highest percentage (100%) of mycorrhizal colonization in Rajshahi University Campus, Bangladesh that was used as a stock plant in pot culture experiment. These root pieces have the ability to serve as a source of mycorrhizal inoculum for crop plants. After using mycorrhizal inoculum, the soil nutrients as well as root colonization for rice plants were greatly affected. Soil nutrients were increased (nitrogen-0.03 times and phosphorus 8 times compared to sterile soil), whereas the percentage of rice roots colonization of arbuscular mycorrhiza (AM) was also increased 9 times after mycorrhizal inoculation. Mycorrhizal enrichment greatly improved the soil nutrients such as nitrogen and phosphorus as well as growth of rice plants.

 

Key words:  Arbuscular mycorrhiza, rice, soil phosphorus, nitrogen.
