Nitrogen fixing Bacteria for Nodulation in Non-Legumes
For the last few decades, efforts have been underway to induce nitrogen fixing bacteria to form root nodules in non-legumes like cereals including rice, wheat and barley or in oil seed crops like rape seed, etc.

These efforts in the past often met with failures. However, during the last few years, groups led by E. Cocking in UK, by Y. Jing in China and by B. Rolfe in Australia were successful in inducing the bacteria to form nodules in the roots of important crop plants like rice, wheat and oilseed rape. Oilseed rape produced high quality industrial oil as well as canola oil, a current favourite for health due to its cholesterol lowering property. It is possible that in future, these may be grown on degraded lands in association with rhizobia, forming nodules.
