Abstract: The field experiments were conducted to evaluate combination of inorganic fertilizers along with organic manures at the Experimental Farm, Department of Agronomy, Annamalai University, Tamil Nadu. The treatments were tested in Split- plot Design and replicated thrice. It was observed that the growth and yield attributes of rice crop viz., no. of panicle m^-2, no. of filled grains panicle^-1 and nutrient uptake were favourably influenced by combined application of inorganic fertilizers and organic manures. The effect of application of 125% NPK + Vermicompost 5 t ha^-1 + Azophos @ 25 kg ha^-1 + Azolla @ 10 kg ha^-1 + Foliar application of Sea weed extract @ 0.2% at 15 and 30 DAT influenced the growth of rice and recorded highest in all aspects no. of panicles m^-2 and no. of filled grains panicle^-1 and NPK uptake which was on par with the application of 125% NPK + Vermicompost 5 t ha^-1 + Azophos @ 25 kg ha^-1 + Azolla @ 10 kg ha^-1.
