Abstract
A field experiment was conducted at crop research centre of SVPUA&T, Meerut (U.P.) India during 2020-21. Novel nutrient sources and their modes of applications with 12 treatments consisting of Control, NPK-(150:60:40 q ha-1), 100 % NPK + Nano Zn spray, 100 % NPK + Bio-stimulant spray, 75 % NPK + NPK Consortia, 75 % NPK + NPK spray, 75 % NPK + NPK Consortia + Nano N spray, 75 % NPK + NPK Consortia + NPK spray, 75 % NPK + NPK Consortia + NPK spray +Bio-stimulant spray, 75 % NPK + NPK Consortia + NPK spray + Bio-stimulant spray + Nano Zn spray, 75 % NPK + NPK Consortia + Nano Zn spray, 75 % NPK + NPK Consortia + Nano N spray + Nano Zn spray were attempted on wheat variety HD 2967 in randomized complete block design (RCBD) with three replications. The application of 75 % NPK + NPK Consortia + NPK spray + Bio-stimulant spray + Nano Zn spray was found at par with 100 % NPK nano Zn / Bio-stimulant and significant over recommended dose of fertilizer (RDF) with a better growth attribute and yield ie. plant population (307.8 no. m-2), plant height (110.6 cm), number of tillers m-1 row length (68.9), dry matter accumulation (294.0 g m-1) and grain yield (55.9 q ha-1 ) with a better availability of nutrients in soil.
