the low bioavailability of zinc (zn) is in calcareous and saline soil, therefore the study of chemical forms and bioavailability of zn in these soils is necessary to estimate the potential availability. the objective of this study was to evaluate the effect of plant growth promoting rhizobacteria and mycorrhizae fungi inoculation on the chemical forms of zn in a calcareous soil at different sal...

plant growth promoting rhizobacteria and arbuscular mycorrhizal fungi can inhanced plant growth by increasing nutrient uptake. in order to investigate the effect of pgpr and amf on some morphological parameters, macro (nitrogen, phosphorus, potassium, calcium and magnesium) and micro (iron, zinc and copper) nutrients uptake, percentage of root colonization and some morphological factors of pepp...

Soil salinity is one of the most widespread agricultural problems which reduce the field crop productivity. Salinity disturbs the hormonal balance in plants which results in poor growth. Use of plant growth promoting rhizobacteria (PGPR) is considered an economical and environment-friendly approach to combat salinity stress. This study was carried out to investigate the effect of auxin producin...

plant growth promoting rhizobacteria (pgpr) are known to influence plant growth by various director indirect mechanisms. thirty–two strains were isolated from 15 soils sampled in central iran, byusing and comparing three different methods. the screening of soil samples by means of soil paste–plate method combined with isolation on mannitol agar proved to be the best strategy in terms ofreliabil...
