Field trial experiments were carried out on rice crop in 2010 using magnetized fly ash (Biosil) as soil conditioner along with recommended dose of fertilizer (RDF), keeping RDF and vermicompost (VC) as controls. Encouraging results on rice plant growth and productivity and soil fertility at very low concentrations (150 to 900 kg/ha) indicated the improved intrinsic soil conditioning power of fly ash. Biosil 900 kg/ha was observed to be the optimum dose for growth and yield parameters of rice. The maximum grain and straw yield of 47.7 and 77.4 q/ha were recorded under RDF+Biosil @ 900 kg/ha as compared to RDF alone (40.2 q/ha). The percentage improvements of soil parameters over initial status by Biosil optimum doses were 2.82% in pH, 2.69% in K, 5.50% in S, 20.83% in Zn, 6.45% in EC, 6.25% in OC, 0.80% in N, - 4.11% in BD and 3.73% in P. The general trend of improvement for growth of rice crop was Biosil+RDF > VC > RDF and for soil parameters was Biosil+RDF > RDF > VC. Thus it is suggested that integrated treatment would be the best for getting maximum benefits from Biosil.
