Parichha thermal power plant is a unit of national thermal power plant situated in Jhansi district of Uttar Pradesh India, which uses bituminous coal for electricity generation. After combustion in boilers this coal comes out from the chimneys and get mixed with air then precipitated in the surrounding area in the form of fly ash which is bring together by electronic precipitators. Present work has been taken to work out the effect of different concentrations of fly ash on the growth and yield of Vigna mungo L. variety T-9 obtained from certified seed centre. Seeds of Vigna mungo L. have been examined under different concentrations of fly ash amended soil. Different plant parameters such as percent of germination, plant height in terms of shoot and root length, fresh weight, dry weight and chlorophyll content have been analyzed along with crop yield. Maximum germination percent i.e. 94% have been recorded from the sample mixed with 25% fly ash and 75% field soil. For other vegetative parameters it has been found that sample 25% fly ash and 75% soil is highly supportive for plant growth. This has been supported by the leaf samples analyzed for chlorophyll content in the fresh leaves, where maximum amount of chlorophyll content has been recorded.
