In order to assess the effect of graded levels of applied magnesium (Mg)(0, 5, 10, 15, 20 and 25 kg ha-1) on the soil available major nutrients, fieldexperiments were conducted in 14 farmer’s holdings at Pudukkottai districtwith hybrid maize (NK 6240) as a test crop. Dry matter production (DMP) ofthe whole plant (above ground) at harvest stage of maize was significantlyinfluenced by the application of 100% NPK + 10 kg Mg ha-1 and recorded thehighest mean as 25620 kg ha-1 at harvest stage. A noticeable increase ingrain and stover yield of maize crop was manifested by applying 100% NPK+ 10 kg Mg ha-1 which recorded the highest mean yield as 11.6 t ha-1 and14.0 t ha-1, respectively. It reported a 14.31 and 22.25 per cent increase ingrain and stover yields, respectively, over control.
