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. |
