Electricity is one of the blessings that science has ever given to mankind but its generation through coal based thermal power stations is a matter of great environmental concern due to one of the byproduct of the process known as fly ash. Proper handling of this huge amount of fly ash is really needed. As we know that fly ash is a coal residue, so it is entirely organic in composition. It has various micro and macro nutrients like soil. Present investigation was carried out at Agra College to evaluate the impact of fly ash on the growth parameters of wheat through pot culture experiments. Soil- ash mixture was prepared and used on wheat variety HD-2967 in different conc’s (0%, 15%, 30%, 50%, 75% and 100%) and positive responses related to different growth parameters were recorded. The amendment of fly ash with elevated conc. (0%-30%) enhanced the germination of seed in test crop. Highest stimulation was noted at 30%-50% fly ash concentration. Further increase in concentration significantly inhibited the growth parameters.
