The experiment was conducted on Inceptisol (Pather series, Vertic Haplustepts) during the year 2009-10 on experimental farm of the Soil Test Crop Response Correlation Project, M.P.K.V Rahuri for evaluation of a scientific basis for calculating the “Nutrient requirement of maize by conjoint use of FYM and chemical fertilizers based on targeted yield approach on Inceptisol”. Based on the fertility gradient approach The validity of these equations were tested by conducting nine follow up trials of maize grain on three soil series of Entisol (Viz.Karwali, Rahuri and Akole),three soil series of Inceptisol (Viz. Pather,Beed and Kolyachiwadi) and three soil series of Vertisol (Viz.Targaon,Ambulga and Babulgaon) during Kharif of 2010-11 Post Graduate Farm, Dairy farm and D block, M.P.K.V. Rahuri. The results revealed that the fertilizer application as per yield target 60, 80 and 100 q ha-1 + 10 t ha-1 FYM to maize crop for validation on different soil series of Entisol (viz., Karwali, Rahuri and Akole), Inceptisol (viz., Pather, Beed and Kolyachiwadi) and Vertisol (viz., Targaon, Ambulga and Babulgaon) inrespect to soil pH and organic corbon content was higher in Vertisols (8.22 and 1.04 %) and Inceptisols order (8.29 and 1.05 %). Electrical conductivity of Vertisols and Entisols was higher (0.138 and 0.135 dSm-1). Residual calcium carbonate content in Inceptisols and Vertisols was more (7.27 and 6.41 %). Addition of fertilizer application as per 60, 80 and 10 q ha-1 yield target + 10 t ha-1 FYM decreased the calcium carbonate content in all the soil series of Entisols, Inceptisols and Vertisols. Thus, fertilizer prescription equation for grain maize developed on Inceptisol can be suitable for Entisol and Vertisol soil order. However, it was more resembling with Vertisol than Entisol.
