Relaxation time (τ•10 12 sec), dispersion amplitudes ( ∆ , ∆ ) and weighting factors according to equations ( 12)-( 13) and ( 14)-( Taken as initial values, the dispersion parameters of pure components were subject to slight variation [19,20]. The final selection of parameters was determined by the minima of the sum of the root-mean-square deviations of the coefficients calculated using these equations (𝜀 , 𝜀 " ) from the measured ones (ε′, ε″):…”

The article presents the results of a study of the temperature dependence of the dielectric constant ε' and the dielectric loss index ε" of the chlorobenzene-iodobenzene system at wavelengths λ = 6.32; 4.01; 3.21; 2.14; 1.18 and 0.75 V temperature range ‑40℃÷+30℃. The static dielectric constant was determined at a frequency of 7 MHz. The temperature dependence of the time of dielectric relaxation of molecules in the liquid state was determined. It was established that in the specified temperature‑frequency range the dispersion region consists of two parts. Analysis of the temperature dependence of dielectric polarization relaxation in the system chlorobenzene-iodobenzene shows that the relaxation times of the components do not depend on their short-range order. It was also discovered that the rate graph showing the dependence of the logarithm of the relaxation time on the reciprocal of the temperature logτ ~ 1/T, consists of two parts and the value of the static dielectric permeability ε∞ is non-additive. To explain these results, it is assumed that clusters are formed in this system, the same as in the pure components.

“…Among the individual inoculants inoculation treatment T 6 (75% RDF + Isolate II) shows maximum chlorophyll a content followed by T 5 (75% RDF + Isolate I), T 4 (75% RDF + AM Fungi) and Reference strain showing chlorophyll a content of 1.79 mg/g, 1.71 mg/g, 1.66 mg/g and 1.59 mg/g respectively (Fig 3). [3] they studied and reported that inoculation with PSB significantly enhanced root length and radicle length of wheat as compared to the individuals. This could be due to the release of plant growth promoting substances by inoculants.…”

Soil microorganisms play a very important role in improving soil fertility and enhancing the plant growth. Bacillus and AM Fungi are the important key component of the soil microbial population. So, the aim of the present study was to investigate the effect of single and dual inoculation of Bacillus spp with Glomus intraradices along with 75% RDF on growth and yield parameters of ragi. The treatment with both strains of Bacillus and G. intraradices showed the highest plant growth parameters like plant hight, number of tillers, Chlorphyll content, Root length and also the treatment with Glomus intraradices showed the highest percent root colonization and spore count at 75 days after transplanting of 90.23% and 178.53% respectively. This is because of the availability of the nutrients uptake, protection of plants against pathogens and mitigation of abiotic stresses like drought, salinity etc. through dual inoculation compared to single inoculation of either Bacillus spp or Glomus intraradices alone.

“…(Khan, et al, 2009). Thus, phosphate solubilizing bacteria (PSB) play an important role in reducing P deficiency in soil (Aipova, et al, 2010).and have attracted the attention of agriculturalists as soil inoculums to improve the plant growth and yield (Fasim, et al, 2002). It has provided their worth as biological alternative to compensate agrochemicals and to sustain environment-friendly crop production (Dobbelaere, et al, 2003).…”

RD).The results revealed that PDB inoculation increased their population in soil and significantly increased the availability of P in calcareous soil whether applied alone or combined with added P forms compared without it, where the treatments of TSP at 75 and 100% RD combined with PDB gave the highest percentage (125.8, 136.4%) at the 50 days age and the lowest percentage (50.9, 53.3%) at harvest, respectively. The results indicated to increase macronutrients uptake by faba bean plants, which positively reflected on quantities and qualities of yields. It can be concluded that adding TSP at 75% RD combined with PDB inoculation is the recommended for improving the productivity of faba bean crop, while the means values of seed yield relatively increased about with 41.4% over the same treatment without PDB and about 34.2, 36.9% for PDB inoculation and TSP forms as individual effect respectively. It was noticed that the PDB-inoculated seeds increased phosphorus use efficiency (PUE), phosphorus agronomic efficiency (PAE) and phosphorus recovery efficiency (PRE) by about 33.04, 101.1 and 138.1%, respectively over the uninoculated. Triple superphosphate (TSP) has the greater efficiency whether it was alone or combined with PDB inoculation at 75% RD addition compared to other forms. Key word: calcareous soil, mineral P forms, phosphate dissolving bacteria (PDB), faba bean.
