    Microbial application for enhancing the yield and quality of Indian Mustard (Brassica juncea) under tarai conditions of Uttarakhand
    (G.B. Pant University of Agriculture and Technology, Pantnagar - 263145 (Uttarakhand), 2021-10) Deesha; Negi, M.S.
    A field experiment was conducted during Rabi season of 2020-21 at Norman E. Borlaug Crop Research Centre of G.B. Pant University of Agriculture and Technology, Pantnagar to study the effect of microbial application along with inorganic fertilizers on growth, yield and yield attributes, quality and economics of Indian mustard. The experiment was laid out in split plot design replicated thrice with three fertility levels viz. 100% RDF, 75% RDF and control as main plot treatments and five microbial consortia viz. Phosphate Solubilizing Micro Organism (PSMO), Azotobacter, Potassium Mobilizing Biofertilizer (KMB), Zinc Solubilizing Biofertilizer (ZSB) and their combination (PSMO + Azotobacter + KMB + ZSB) as sub-plot treatments. The soil of the experimental plot was silty clay loam in texture with neutral in reaction (pH 6.9), medium in organic carbon (0.71%), low in available nitrogen (245 kg/ha), medium in available phosphorus (22.2 kg/ha) and medium in available potassium (251 kg/ha). The growth and yield attributes influenced significantly with different fertility levels and microbial consortia. The significantly higher plant height, number of branches per plant, dry matter accumulation, yield attributes, seed yield, oil yield and protein yield was obtained at 100% RDF with the combination of PSMO + Azotobacter + KMB + ZSB. A dose of 100% RDF gave significantly higher yield (2204 kg/ha) of mustard over 75% RDF (2006 kg/ha) and control (1218 kg/ha). Mustard crop also gave significantly higher yield when grown in the plots having the combination of PSMO + Azotobacter + KMB + ZSB (2178 kg/ha) compared to separate use of Phosphate Solubilizing Micro Organism (1919 kg/ha), Azotobacter (1658 kg/ha), Potassium Mobilizing Biofertilizer (1721 kg/ha) and Zinc Solubilizing Biofertilizer (1571 kg/ha). The significantly higher yield (2884 kg/ha) was obtained when crop was grown with 100% RDF along with the combination of PSMO + Azotobacter + KMB + ZSB. The net returns were higher at 100% RDF and in the combination of PSMO + Azotobacter + KMB + ZSB. A dose of 100% RDF along with the combination of PSMO + Azotobacter + KMB + ZSB gave higher net returns. Similarly, B:C ratio was higher at 100% RDF along with the combination of PSMO + Azotobacter + KMB + ZSB. From the above findings, it can be concluded that Indian mustard NRCHB 101 grown at 100% RDF along with the combination of PSMO + Azotobacter + KMB + ZSB resulted in higher yield and more economic return. Therefore, Indian mustard NRCHB 101 can be grown at 100% RDF (i.e. N-P2O5-K2O-S : 120-40-20-20 kg/ha, respectively) along with the combination of PSMO + Azotobacter + KMB + ZSB. However, these findings are based on one-year data which need to be validated by conducting further experimentation.
