Abstract

The field experiment was carried out during the Rabi season of 2021-22 at the experimental block of the School of Agricultural Sciences of the Shri Guru Ram Rai University (SAS-SGRRU), Pathribagh, Dehradun, Uttarakhand to study the effect of various nutrient management approaches on growth, yield and net profit of wheat crop. The experiment was laid out in Randomized Complete Block Design (RBD) with eight treatments viz., Control (T1 );Vermicompost @ 5 t ha(^-1+ Seed inoculation with Bijamrit + 50 % RDF (T2 ); Vermicompost @ 5 t ha-1+ PSB seed inoculation + 25 % RDF(T3 ); FYM @5 t ha-1+ PSB seed inoculation + 2 foliar spray of fermented buttermilk (T4 ); 50% RDF + FYM @5 t ha^-1+ mulching @ 5 t ha^-1 (T5 ); 25% RDF + Jivamrit + seed inoculation with Bijamrit + 2 foliar spray of vermiwash + 2 foliar spray of fermented buttermilk (T6 ); FYM @5 t ha^-1+ Bijamrit seed inoculation + 2 foliar spray of vermiwash (T7 ) and 100 % RDF (T8 ) which were replicated 3 times. The soil of the experimental field was sandy loam with low available nitrogen and organic carbon, medium available phosphorous and available potassium Application of 50 % RDF + FYM @ 5t ha^-1+ mulching has recorded more yield which is significantly higher than other nutrient management approaches. Substitution of 50 % inorganic fertilizers with FYM can be adopted for economically viable and sustainable wheat production with improved yield in irrigated conditions of Doon Valley areas of Uttarakhand
