Abstract:
A research work titled “Fortification of hybrid maize through soil and foliar application of nutrients” was carried out at Agricultural College and Research Institute, Killikulam during summer 2021. The trial framed in Randomized Block Design consisting of 10 treatments, replicated thrice. The treatment incorporated with the micronutrient application of zinc and ferrous sulphate as foliar, soil application and also combined application and also the application of TNAU Micronutrient mixture and Maize maxim. The observations that were recorded are quality parameters and economics. The results revealed that the crude protein (14.06%), zinc (41.3 mg kg^-1) and iron content (90.8 mg kg-¹) was also increased in T_7. In terms of economics the gross return (Rs.133910 ha^-1) and net return (Rs.85039 ha^-1) was higher in T₇ and the B:C ratio (2.79) was higher in T₅ (STCR based NPK + 30 kg TNAU Micronutrient mixture as enriched FYM) in hybrid maize. The lowest values for yield and quality parameters were recorded in the absolute control (T₁₀).
