Abstract: A field study was carried out at Dr Y S Parmar University of Horticulture and Forestry, Nauni, Solan (H P) during 2015-2016 to study the effect of INM on biological properties of soil and nutrient uptake in cauliflower (Brassica oleracea var botrytis L.) Nine different treatments with three replications each were carried out in the plot of RBD design. The nine treatments, T₁ -Absolute control, T₂ -70% NPKM + 30% N through FYM and VC (50:50), T₃ -80% NPKM + 20% N through FYM and VC (50:50), T₄ -90% NPKM + 10% N through FYM and VC (50:50), T₅ -100% NPK + FYM, T₆ -100% NPK + Vermicomposting, T₇ -110% NPKM (50:50 of FYM and VC as per N content), T₈ -120% NPKM (50:50 of FYM and VC as per N content), T₉ -130% NPKM (50:50 of FYM and VC as per N content). PGPR applied to all treatments except T_1, T₅ and T₆. The biological property of soil was significantly enhanced by the application of combined use of organic, inorganic fertilizers and PGPR after harvest of crop during both the years of experimentation. Results revealed that treatment T₂ -80% NPKM + 30% N through FYM and VC (50:50) with PGPR, significantly enhanced the biological properties of soil and nutrient uptake in cauliflower.
