This investigation was conducted in maize (kharif, 2013) in the ongoing long-term experiment on soil test crop response correlation studies (STCR), initiated during kharif, 2007 at the experimental farm of CSK Himachal Pradesh Krishi Vishvavidyalaya, Palampur to evaluate different approaches of fertilizer recommendations to maize. The prescription based nutrients application based on STCR approach for realizing yield target of 40 q ha-1 with and without FYM proved significantly better as compared to conventional soil test based (STB) approach as well as general recommended dose (GRD) for the productivity as well as uptake of micronutrients. Fertilizers application based on STCR along with FYM for yield target of 40 q ha-1 enhanced the grain yield by 35 % and 33% over GRD and STB, respectively. Whereas, in case of STCR based fertilizers application without FYM for same yield target the yield increments over GRD and STB were 32 and 30%, respectively. The uptake of Fe, Mn, Zn and Cu by maize grains increased by about 41, 44, 41 and 63%, respectively following fertilizers application based on STCR along with FYM for yield target of 40 q ha-1 in comparison to GRD.
