Effect of validation of fertilizer prescription equations of kharif grain maize on grain and stover yield


Author(s): Ghodke PD

Abstract: Main experiment was conducted 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”. The experiment was conducted on Inceptisol (Pather series, Vertic Haplustepts) during the year 2009-10, 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 Khari 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) were achieved the targeted yield with (+ 10%). 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.
