Field experiment was conducted under Alfisols at KVK, Farm Katghora, Korba and Vertisols at Instructional Farm Indira Gandhi Krishi Vishwavidyalaya, Raipur during 2011,2012and2013.To assess the effect of different doses of fly ash alone or in combination with manure and fertilizers in rice –wheat cropping system with Sixteen treatments (i.e. T1Control, T2- 10 t FA ha-1, T3-20 t FA ha-1 T4-STCR (based fertilizer recommendation), T5-75 % NPK ha-1, T6-100 % NPK (100:60:40), T7-75 % NPK ha-1+ 10 t FA ha-1, T8-75 %NPK ha-1 + 20 t FA ha-1, T9-100 % NPK ha-1+ 10 t FA ha-1, T10-100 % NPK ha-1 + 20 t FA ha-1, T11-75 % NPK ha-1+ 5 t FYM ha-1, T12-100 % NPK ha-1 +5 t FYM ha-1, T13- 75 % NPK ha-1 + 5 t FYM +10 t FA, T14- 75 % NPK ha-1 + 5 t FYM +20 t FA ha-1, T15-100 % NPK ha-1 +5 t FYM+10 t FA ha-1 and T16- 100 % NPK ha-1 +5 t FYM+20 t FA ha-1) under Split Plot Design with factorial arrangment of crop and soil in main plot and treatment in sub plot.The microbial biomass carbon and dehydrogenase activity in soil at harvest of crops was significantly increased due to addition of fly ash and FYM in rice-wheat cropping system in Alfisol and Vertisol. The treatment, T16 recorded highest microbial biomass carbon and dehydrogenase activity during the year 2011, 2012 and pooled data. The interaction of crop x soil x treatments was non-significant
