Abstract: A field study was established during Kharif season of 2013 and 2014 at the Agricultural Research Farm, BHU, Varanasi to find out the effect of PGPR and zinc enriched FYM on physio-chemical properties of soil after harvesting of rice crop at different levels of phosphorus in an Inceptisol. The treatment combinations consisted five levels of enriched FYM (M0= control, M1= without enriched FYM, M2= PGPR enriched FYM, M3= PGPR and Zn @ 2.5 kg ha-1 enriched FYM and M4= PGPR and Zn @ 5.0 kg ha-1 enriched FYM) and four levels of phosphors (P0 = 0, P1 = 20, P2 = 40 and P3 = 60 kg P2O5 ha-1). The results of experiment revealed that application of different enriched FYM and P2O5 levels did not showed significant effect on bulk density (Mg m-3), pH and EC (dS m-1) of the soil. Organic carbon was increased significantly due to application of enriched FYM but it was not affected significantly by different levels of phosphorus. Different kinds of enriched FYM significantly increased available nitrogen, phosphorus and potassium in the soil after harvesting of rice during both years. Available nitrogen (224.59 and 227.73 kg N ha-1), phosphorus (20.33 and 22.05 kg P2O5 ha-1) were found highest in the treatment of PGPR and Zn @ 5.0 kg ha-1 enriched FYM (M4) but they were remaining at par with treatment PGPR and zinc @ 2.5 kg ha-1 enriched FYM (M3) during both the years. Available potassium (203.28 and 205.46 kg K2O ha-1) was found highest but it was significant over control (M0) and without enriched FYM (M1) during 2013 and 2014, respectively. The treatment P3 (60 kg P2O5 ha-1) significantly increased the highest available N and P2O5 (kg ha-1) over control but available nitrogen was found at par with the treatment of P2 (40 kg P2O5 ha-1) and available potassium did not show significant effect with different levels of phosphorus. Interaction effect of enriched FYM and P2O5 levels was found significant and obtained PGPR and zinc @ 2.5 kg ha-1 enriched FYM + 40 kg P2O5 ha-1 most effective treatment combination at farmers level due to reduction in 20 kg P2O5 ha-1 and 2.5 kg Zn ha-1 in the recommended dose of P and Zn for optimum yield along with maintenance of soil health. PGPR and zinc @ 5.0 kg ha-1 enriched FYM increased significantly available Zn (0.70 and 0.75 ppm) in soil over control but found statistically at par with PGPR and zinc @ 2.5 kg ha-1 enriched FYM during both years. Higher available Zn was found significant with application of 60 kg P2O5 ha-1 over control and showed at par result with 40 kg P2O5 ha-1.
