“…AMF are known to improve uptake of nutrients such as phosphorus, potassium, nitrogen and the micronutrients zinc and copper (Smith and Read, 1997) but reports on iron uptake by AMF are scarce. An increase in iron concentration in maize and sorghum mycorrhizal plants has been reported (Clark and Zeto, 1996;Caris et al, 1998). However, contrary to the observation of these authors, the soils used in this study were neither alkaline nor Fe-depleted (see Table 1).…”

The goal of this study was first to assess the dynamics of the bacterial community during a growing season in three Indian rain-fed wheat fields which differ mainly through their fertilizer management and yield and then to study the effects of PGPR/AMF bio-inoculations on the bacterial community structure and wheat growth. The bacterial community structure of the rhizosphere soil (RS) and the rhizoplane/endorhizosphere (RE) was determined by PCR-denaturing gradient gel electrophoresis. Seed treatments consisted of consortia of two PGPR strains alone or combined with AMF or AMF alone. The PGPR strains were Pseudomonas spp. which included some or all of the following plant growth promoting properties: phosphate solubilisation and production of indole-3-acetic acid, siderophores, 1-aminocyclopropane-1-carboxylate deaminase and diacetyl-phloroglucinol. The mycorrhizal inoculum was an indigenous AMF consortium isolated from the field with the lowest level of fertilization and yield. Variation partitioning analysis of the DGGE data indicated a predominant effect of the wheat growth stage (30.4% of the variance, PZ0.001) over the type of field (9.0%, PZ0.027) on the bacterial community structure in the RE. The impact of plant age in the RS was less than in the RE and the bacterial community structure of the field with the highest input of fertilization was very different from the low input fields. The bio-inoculants induced a significant modification in the bacterial community structure. In the RS, the bacterial consortia explained 28.3% (PZ0.001) and the presence of AMF 10.6% (PZ0.02) of the variance and the same trend was observed in the RE. Plant yield or grain quality was either increased or remained unaffected. For example, protein content was significantly higher in the treated plants' grain compared to the control plants; maximum values were obtained when the PGPR were co-inoculated with the AMF. The percentage of root colonization by AMF was significantly higher in the treatments containing a mycorrhizal inoculum than in the untreated control and remained unaffected by the PGPR treatments. In conclusion, the wheat rhizobacterial community structure is highly dynamic and influenced by different factors such as the plant's age, the fertilizer input and the type of bio-inoculant. In addition, there is a distance-related effect of the root on the bacterial community. Finally, a combined bio-inoculation of diacetyl-phloroglucinol producing PGPR strains and AMF can synergistically improve the nutritional quality of the grain without negatively affecting mycorrhizal growth.

“…Concentration of Mn in wheat plant as affected by sulphur applied with compost is given in Table 8 [95] founded that pH reducing agents such as sulphur and sulphuric acid improves the properties of calcareous soils and enhanced the concentration of nutrients, including micronutrients. [93] reported that using organic fertilizers the organic matter of the soil increases and thus increases the concentration of Fe, Zn, Cu, Mn, N, P, and K in plant.…”

A field experiment was conducted to determine the effect of sulphur application with Rock phosphate mixed compost on phosphorus (P) solubility and its effect on yield and P uptake of wheat crop. The experiment was laid out in randomized complete block design (RCBD) with three replications at the research farm of The University of Agriculture Peshawar. The experiment was conducted during rabi 2015-16 with plot size of 3 m × 5 m. Nitrogen, phosphorus and potassium were applied at the rate of 120, 90 and 60 kg•ha −1 in the form of urea, compost, or single super phosphate and potassium sulphate, respectively. Elemental sulphur was applied at the rate of 10, 20 and 30 kg•ha −1 at the time of sowing. Results showed that sulphur applied with compost significantly improved wheat yield and yield components, soil organic matter, soil total N and AB-DTPA extractable P contents, plant N and P concentrations and their uptake, plant micronutrients concentration and their uptakes. No significant changes were noted in soil pH, ECe and lime contents. Maximum grain yield of 4076 kg•ha

“…In other studies, G. etunicatum, G. intraradices, and G. diaphanum maize grown in two acidic soils (pH Ca 4.2 and 4.6) had no differences in P RL values. [10] Zn RL values were higher for S. calospora subterraneum clover than for either Glomus sp. or A. laevis plants, while A. laevis plants had slightly higher Zn RL values than Glomus sp.…”

“…[2][3][4][5][6][7] One beneficial effect of AMF for alleviating mineral stresses in acidic soil has been attributed to the ability of AMF hyphae to extend beyond the usual nutrient absorption zone of roots and transport essential nutrients to the host plant that roots per se would not otherwise contact, especially P. [2] Improved tolerance of plants to acidic soil may also be attributed to restricted acquisition of and=or exposure to toxic elements, especially Al and Mn. [6,[8][9][10][11][12][13][14][15][16][17][18][19][20] Plant species and genotypes within species exhibit large differences for tolerance to acidic soils, [21][22][23][24] and so do AMF species and isolates differ in providing plant tolerance to acidic soil. [6,9,11,15,16,[25][26][27][28] Much of this has been attributed to AMF enhancement of essential mineral nutrient acquisition and providing plant protection against toxic elements.…”
