A randomized block design having two factors with three levels of @ NPK 0, 50, and 100% ha-1, three levels of @ FYM 0, 50 and 100% ha-1 and Azospirillum respectively. The best treatment was effect on physical and chemical property of soil and yield attributes in T8 (NPK @100% + FYM @ 6 t ha-1 + Azospirillum @ 1 kg ha-1) of rice. Post-harvest soil and pre harvest plant resulted significantly maximum values of percentage pore space (%) with depth 0-15 cm and 15-30 cm 49.89 % and 47.55 %, water holding capacity (%) with depth 0- 15 cm and 15-30 cm 44.66 % and 43.22 % , EC (dS m-1 ) with depth 0-15 cm and 15-30 cm 0.26 dS m-1 and 0.22 dS m-1 , organic carbon (%) with depth 0-15 cm and 15-30 cm 0.67% and 0.63% , Av. Nitrogen (kg ha-1 ) with depth 0-15 cm and 15-30 cm 295.09 kg ha-1 and 291.76 kg ha-1 , Av. Phosphorus (kg ha-1 ) with depth 0-15 cm and 15-30 cm 31.45 kg ha-1 and 29.27 kg ha-1 , Av. Potassium (kg ha-1 ) with depth 0-15 cm and 15-30 cm 213.89 kg ha-1 and 20.323 kg ha-1 , The maximum cost benefit ratio (C:B) 1:3.19, maximum gross return 1,85,612.00, maximum net profit 1,27,488.00 ha-1 and highest Grain yield as 44.86 q ha-1 , straw yield 63.88 q ha-1 with T8 (NPK @100% + FYM 6 t ha-1 + Azospirillum @ 1 kg ha-1).
