About the Cover

Paper Mill is a wood based power plant which generates a huge amount of fly ash. The application of fly ash in degraded land may reduce the problem of disposal to some extent. A field study was carried out on a sandy loam soil at the KVK farm Janjgir Champa, Chhattisgarh to study the effect of enriched fly ash (FA) on rice and soil characteristics of inceptisol during kharif 2013-14. The test crop was rice var. MTU-1010. The application of different treatment FA combinations increased paddy yield compared to 100% GRD. However the control treatment failed to produce the yield in degraded land. Among the treatments, the 75% GRD +60t FAha-1+5t FYMha-1 gave highest paddy yield than all other treatments. The straw yield was not significantly influenced by FA treatments, but the beneficial effect of enriched fly ash on higher rice straw yield was observed. Application of 75% GRD + fly ash@ 60 t ha-1 + FYM @ 5 t ha-1 recorded the highest soil available phosphorus, potassium and zinc compared to other treatments and soil available N was highest in application of 75% GRD + fly ash@ 40 t ha-1 + FYM @ 5 t ha-1. The soil available Cu, Mn and Fe content were not significantly influenced by different combination of FYM, FA and Fertilizers. The treatment 75% GRD + 40 t FA ha-1 + 5 t FYM ha-1 (T7) was the maximum available chromium and Nickel, Lead and Cobalt as not influenced by the different doses of fly ash (ref: lal B, kumar H, Painkra B, Solanki D, Tedia K.
