Influence of Long Term Fertilizer Application on Nutrient Addition through Root Biomass in Maize

An experiment was conducted in long-term fertilizer experiment field at the ZARS,GKVK,Bangalore duringRabi 2010-11to find out the effect of continues applied fertilizers on maize ischolar_main biomass and nutrient addition through ischolar_main biomass. Long term fertilizer application showed significantly higher (12.94 q ha^-1) ischolar_main biomass and ischolar_main length (22.35 cm) in T₃ which received 150 % NPK followed T₈ and T₁₀ which received FYM and lime along with inorganic fertilizers showed a better results (12.65q ha^-1, 12.12q ha^-1 and 21.33cm, 19.73 cm, respectively). The higher major, secondary and micronutrients content in maize ischolar_mains were recorded in the T₃ which received super optimal doses of NPK fertilizers (150 % NPK) and also in the plots which received 100 % NPK + FYM + lime, respectively over control.The higher uptake of nutrients by ischolar_main biomass also showed similar results.
