Abstract: Field experiment was conducted under Alfisols at KVK, Farm Katghora, Korba and Vertisols at Instructional Farm Indira Gandhi Krishi Vishwavidyalaya, during 2011 and 2012. To assess the impact of different doses of fly ash alone or in combination with manure and fertilizers on available heavy metals in rice –wheat cropping system in Alfisols and Vertisols in the following 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 available soil Cd, Ni, Cr and Pb significantly increased due to addition of fly ash in Alfisols and Vertisols in rice-wheat cropping system. The higher available Cd, Ni and Cr content in soil was recorded in Alfisols under both the crops in treatment T16 and interaction of soil x crop x treatment was non-significant. The available Pb content in soil influenced due to addition of fly ash, interaction between rice × Vertisol × treatment and rice × Alfisol × treatment, T16 recorded significantly highest available lead content in soil among all the treatments. It was at par with treatment, T14 and T10 in rice × Vertisol × treatment and T14 in rice x Alfisol × treatment. In case of wheat × Vertisol × treatments and wheat × Alfisol × treatment, T16 recorded higher available lead content in soil. It was at par with T15 in wheat × Vertisol × treatment and T15 and T14 in wheat × Alfisol × treatment. The lowest available lead content was recorded in T1.
