Context 1
... scrutiny of data presented in Table 5 on the effect of integrated nutrient management on availability of sulfur showed that available sulfur in soil ranged from 24.36 to 34.10 kg ha -1 . Application of 100% RDN through vermicompost + Azotobacter (T11) was found to be statistically superior over all the treatments except T10 (25% RDN through inorganic fertilizer + 75% RDN through vermicompost + Azotobacter) and lowest sulfur availability was observed under control (T1). ...Context 2
... referred in connection with the effect of integrated nutrient management on exchangeable calcium content in Table 5 marked out that among all the treatments, maximum exchangeable calcium [14.12 c mol (p+) kg -1 ] in soil was reported with the application of 100% RDN through vermicompost + Azotobacter (T11) followed by 100% RDN through vermicompost (T6). Whereas, minimum values [8.18 c mol (p+) kg -1 ] of exchangeable calcium were obtained under control (T1). ...Context 3
... to exchangeable calcium different treatments also had significant effect on exchangeable magnesium as it increased with the application of fertilizer or vermicompost or both with or without the Azotobacter (Table 5). An inquisition of data indicated that maximum content of exchangeable magnesium [2.87 c mol (p+) kg -1 ] was observed with the application of 100% RDN through vermicompost + Azotobacter (T11) and lowest [2.35 c mol (p+) kg -1 ] under control (T1) where no inorganic fertilizer, organic manure or biofertilizer application was done. ...Context 4
... data with respect to effect of integrated nutrient management on DTPA extractable zinc have been presented in Table 5. DTPA extractable zinc varied from a minimum of 0.85 mg kg -1 in control (T1) to a maximum of 1.01 mg kg -1 in plots receiving 100% RDN through vermicompost along with Azotobacter (T11). ...Context 5
... appraisal of data presented in Table 5 on effect of integrated nutrient management on DTPA extractable copper showed that copper content in soil ranged from 1.04 to 1.35 mg kg -1 where maximum value was observed under treatment T11 (100 % RDN through vermicompost + Azotobacter), while minimum under T1 (control). Use of 100% RDF in conjunction with Azotobacter (T7) increased the copper content in soil over sole application of 100% RDF (T2). ...Context 6
... examination of data presented in Table 5 on the effect of integrated nutrient management on DTPA extractable iron depicted that the iron content in the soil varied from 12.87 to 15.78 mg kg -1 and the highest iron content was registered with the application of 100% RDN through vermicompost + Azotobacter (T11) and lowest from control (T1). The treatments receiving 100% RDF (T2) showed increased iron content over control, however it was found to be inferior over the application of 100% RDF along with Azotobacter (T7). ...Context 7
... perusal of data presented in Table 5 on the effect of integrated nutrient management on DTPA extractable manganese in soil revealed the significant effect of different treatments on manganese content in soil over control. The highest manganese content (16.02 mg kg -1 ) was obtained in treatment T11 (100 % RDN through vermicompost + Azotobacter) while lowest (13.34 mg kg -1 ) was observed under treatment T1 (control). ...Similar publications

... The increase in available nitrogen might be due to direct absorption of nitrogen by the soil which enhanced microbial activity and consequent released to organic complexing substances [6]. The increase in available N with the application of Azotobacter might be due to improved nitrogen availability in the rhizosphere and addition of organic manure may also be attributed to higher microbial activity in the integrated nutrient management treatments which favoured the conversion of the organically bound nitrogen into inorganic form as reported byThakur et al. [30]. Nainwal et al. [31] also reported that available nitrogen can be highest by addition of nitrogenase fertilizers like Azotobacter applying with NPK. ...
An experiment was conducted during rabi season, 2021 to investigate the effect of integrated nutrient management on soil nutrient status in garlic. The study was structured around eighteen treatments with combinations of inorganic fertilizers, biofertilizers and organic manures like Jeevamrit and Beejamrit. The treatment T12 [(75 % RDF + 40 kg Sulphur/ha + Azotobacter + Phosphate Solubilizing Bacteria + FYM (25t/ha)] resulted in minimum soil pH (6.82) and electrical conductivity (0.181 dSm-1) as well as highest organic carbon (0.86 %), available Nitrogen (258.84 kg ha-1), Phosphorus (26.72 kg ha-1) contents. Further, the treatment T17 [(100 % RDF + FYM (25t/ha)] recorded maximum available Potassium (180.35 kg ha-1) and treatment T16 [(100 % RDF + 40 kg S/ha + FYM) recorded highest S (44.98 kg ha-1) contents. Thus, it can be concluded that integration of inorganic fertilizers with biofertilizers and organic manures helps in improving the soil nutrient status.
