Fly ash (FA) from Chandrapura Thermal Power Station in Jharkhand, India were used to amend soil from fallow land in the proportion equivalent to 60, 120, 180, 240 tons.ha in selected vegetables and 10, 20, 30, 40, 50% in selected leguminous crops economically grown in the region, and performance of individual species has been evaluated. In both the studies significant improvement has been observed in soil properties and seed germination with the amendment of FA. Species performance has been incrased in terms of growth (root & shoot length, root shoot ratio, fresh and dry weight) and yield (In terms of seeds and fruit weight per plant) corresponding to different proportion of amendment. Pigment concentration (Chlorofil a & b) have improved at moderate concentration of FA ( 120 & 180 tons/ha) in almost all the species. At the highest concentration (240 tons/ha) of FA the pigment concentration has further decreased. Based on the data obtained it is found the fallow land soil amendment at the rate of 20, 30 & 40% and 120 & 180 tons/ha Fa improved the physical properties of the soil on one hand and contributed to better growth and yield of crops on the other hand.
