Field experiments were carried out during Kharif seasons of 2013-14 and 2014-15 at the Agricultural Research Farm, Banaras Hindu University, Varanasi (U.P.) to study the effect of PGPR and Zinc enriched FYM on yield and growth attributes of rice at different levels of phosphors in an Inceptisol of Varanasi. The treatments consisted five levels of enriched FYM (M0= No FYM, M1= only 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 (0, 20, 40 and 60 kg P2O5 ha-1). The experiment was replicated thrice in a Randomized block design in Factorial experiment. The results showed that, the application of PGPR and Zinc enriched FYM was significantly increased the yield and growth attributes of rice. All the growth and yield attributes showed that treatment M4 was found significantly highest over all the treatments but it was at par with treatment M3 except plant height. As regards the 4 levels of phosphors (0, 20, 40 and 60 kg P2O5 ha-1), an application of 60 kg P2O5 gave the significant highest result over the control and all other treatments for yield and growth attributes of rice except chlorophyll content. Interactive effects of enriched FYM and phosphorus levels were found significant on plant height, grain yield, straw yield and biological yield. Application of PGPR and Zn @ 5.0 kg ha-1 enriched FYM along with 60 kg P2O5 ha-1 resulted in markedly higher plant height (109.07 cm), grain yield (59.62 q ha-1), straw yield (79.94 q ha-1) and biological yield (139.56 q ha-1) but showed at par result with PGPR and Zn @ 2.5 kg ha-1 enriched FYM applied in conjunction with 40 kg P2O5 ha-1. The aim of this experiment was to minimize excess use of fertilizers for optimum yield and quality of rice without harming soil and environment health by the application of PGPR and Zinc enriched FYM.
