A field experiment was conducted at Varanasi, Uttar Pradesh during the year 2008-09 in kharif and rabi season to see the effect of PGPR and FYM on growth with different doses of organic fertilizers on soil fertility status, soil health and enzymatic activity of rice-wheat cropping sequence. Significantly Effect the maximum and superior after one year of rice –wheat cropping sequence bulk density(1.25 Mg-3),water holding capacity(58 %),available nitrogen(246.69 kg/ha ), available potash (239.86 kg/ha ), and dehydrogenase activities (152.651), phoshphase activities (30.293) urease activities (4.491) use on kharif rice on treatment of 36 t FYM ha1 + and PGPM (Azotobactor + Azospirullum + Aspergillus + Tricoderma + PSB. and rabi wheat on treatment of 36 t /ha FYM with PGPR (Azotobactor + tricoderma) +PSB (P.flurescence + P.putida + B.megatera + B.polymyxa). The application of different treatment did not affect the pH, Ec, and bulk density decreased CEC significantly improved after rice- wheat sequence. Positive impact of soil fertility and enzymatic activity status recorded.
