An interrelationship between introduced and indigenous rhizobia focused on their competitiveness in nodulation was evaluated in a soil pot experiment. Clover seeds were inoculated by six different gradual concentrations of inoculum of two effective Rhizobium leguminosarum bv. trifolii isolates (inoculation strains 1/2 and 14/2). At the beginning of flowering, clover plants were removed from the...
Sheep wool can be a waste products of sheep husbandry. Its safe utilization evokes several serious problems. Therefore, it was of interest to check out the usefulness of wool as a fertilizer and/or substrate. The aim of the experiments reported in this paper was to evaluate the effect of the washed sheep wool used as an amendment to peat-based growing substrate on growth and yield of tomato, sw...
We studied the effects of soil temperature (8 °C and 15 °C) on barley growth, barley phosphorus (P) uptake and soil P solubility. Barley was grown in a pot experiment in two soils with different P fertilization histories for 22 years. The availability of P was estimated by using 33P-labeled fertilizer and calculating L-values. After cultivation for 22 years at ambient soil temperature without P...
In this work, we described an in vitro system adequate for investigating the pathosystem soybean/arbuscular mycorrhizal fungi (AMF)/Fusarium virguliforme. Pre-mycorrhized plantlets with Rhizophagus irregularis were infected by F. virguliforme either locally via a plug of gel supporting mycelium (Method 1) or via a macroconidia suspension applied to the medium surface (Method 2). Root colonizati...
A pot experiment was performed to study the effectiveness of remediation using different plant species and the enzyme response involved in remediating PAH-contaminated soil. The study indicated that species Echinacea purpurea, Festuca arundinacea Schred, Fire Phoenix (a combined F. arundinacea), and Medicago sativa L. possess the potential for remediation in PAH-contaminated soils. The study al...
Weathering of K-bearing minerals as the major source of potassium in soils is of special importance under K deficient conditions. Many studies have been carried out on the effect of plant types and microorganisms on the transformation of micaeous minerals and their potassium release. However, there is no information on the effect of organic matter on mineralogical changes in micaceous minerals....
In order to evaluate of the photosynthetic traits of lentil cultivars under water deficit conditions an experiment was conducted as a factorial arrangement in a completely randomized design with three replications in pot cultivation with four cultivars including Gachsaran, Kimia, Ziba, Robat and four stress levels of 25, 50, 75 and 100% of field capacity. Results showed that in all three phenol...
Like many English-dominant nations, Australia has a rich history of cultural and linguistic diversity. This diversity is the result of a melting pot of languages including languages spoken by Australia’s Indigenous people and languages added by European settlement and subsequent waves of migration from various parts of the world. Despite this rich history of linguistic diversity, little has bee...
