The experiment was conducted to evaluate the effect of foliar application of fly ash (0.00, 0.25, 0.50, 1.00, 2.00 and 4.00 g/m2/day) on plant growth, yield, biomass, photosynthetic pigments, NPK (Nitrogen, Phosphorus, Potassium) concentrations of plants and protein and carbohydrate contents of tubers. Dusting of fly ash caused a significant adverse effect on all the above parameters in all the doses, except in 0.25 g/m2/day dose. The epidermal characters of leaves were also observed. The number and size (length and width) of stomata and size (length and width) of stomatal aperture on both the surfaces gradually and significantly decreased in general with the increase in fly ash doses, whereas the number and length of trichomes were increased in all the doses of fly ash.
