Field experiments were conducted during 2010-12 at Regional Research Station, Virudhachalam to find out the residual effect of fly ash, farm yard manure and fertilizers applied to groundnut on growth parameters, nutrient uptake, yield of sesame and post-harvest soil available nutrients. The Neyveli Lignite Corporation fly ash contained higher amount of Ca, Mg, S and Si, moderate amount of P, K and B. Application of fly ash @ 40 t/ha significantly increased growth parameters, yield attributes, seed yield and harvest index of sesame. Combination of FYM + STCR based NPK recorded higher growth characters, yield parameters and seed yield of sesame crop. Application of fly ash @ 40 t/ha significantly improved nutrient uptake by residual sesame crop and post-harvest soil available nutrients in groundnut – sesame cropping system. Maximum nutrient uptake by sesame and post-harvest soil fertility status were registered under application of FYM + STCR based NPK.
