Fly-ash disposal has a signicant impact on terrestrial and aquatic ecosystems. Present investigation has been carried out to study the effect of different fly ash amendment levels on growth of green manure crop Sesbania cannabina. Fly ash obtained from IFFCO (Indian Farmers Fertilizers Cooperative Limited), Phulpur, Allahabad, India was mixed with garden soil in four different concentrations i.e. 0% (control/garden soil), 25%, 50%, 75% and 100%. A portion of the soil-fly ash mixtures was separated for physio-chemical properties. Dry and healthy seeds of Sesbania cannabina were soaked in water for 14 hrs and were sown in different amendment levels of fly ash in triplicates. Data for germination and survival percentages were taken after 15 and 30 days of sowing, respectively. Data for all morphological parameters were taken after 45 days of sowing. The result of present study concludes that the fly ash amendment in soil upto 75% has no adverse effect on the growth of Sesbania cannabina and it offers an eco-friendly method for removal of fly ash wastes from environment.
