Phosphobacteria is one among the soil microorganisms which plays an important role in improving the chemical and physical nature of the soil, adding organic matter to soil, solubilizing the insoluble phosphate increasing availability and utilization of growth and yield. The phosphate solubilizing bacteria, which were inoculated with Avicennia officinalis seedlings, increased significantly the a...
Grapevine training systems determine the suitability for grape varieties in a specific growing region. We evaluated the influence of three training systems, Single Guyot (SG), Spur-pruned Vertical Shoot-Positioned (VSP), and Four-Arm Kniffin (4AK), on the performance of grapes and vines of Vitis vinifera L. cv. Cabernet Sauvignon in the 2012 and 2013 growing seasons in a wet region of central C...
Concentrations of polycyclic aromatic hydrocarbons (PAHs), polychlorinated biphenyls (PCBs), and chlorinated pesticides (CPs) were measured in air and precipitation at a background site in central Europe. ∑ PAH concentrations in air and rainwater ranged from 0.7 to 327.9 ng m and below limit of quantification (< LOQ) to 2.1× 10 ng L. The concentrations of PCBs and CPs in rainwater were < LOQ. ∑...
In a previous study, selective degradation of carbohydrates versus lignin in buried woods was demonstrated by non-destructive spectroscopy (C NMR) and destructive wet chemical methods (acid hydrolysis and alkaline CuO oxidation). In this paper, spruce, alder and oak woods deposited in coastal sediments and their recent equivalents are characterized by pyrolysis-mass spectrometry and pyrolysis-g...
To evaluate the effects of different levels of iron (Fe) (from Fe-nano-chelate and Fe-EDDHA sources) on growth parameters, concentration and absorption of Fe and some nutrients in cowpea (Vigna unguiculata) in a calcareous soil, a greenhouse experiment was conducted based on completely randomized design with three replications. Treatments consisted of four levels of Fe (0, 0.135, 0.270 and 0.40...
Nitrogen (N) is usually low in the majority of agricultural and non agricultural soils in Iran, mainly due to the lack of adequate soil organic matter (OM). On the other hand, boron (B) toxicity is becoming more widespread in arid and semi arid regions of this country, where soils or irrigation waters contain relatively high B content. Results of the research indicate that addition of certain p...
Analysis of heavy metals in top soil samples from Nzoia sugarcane farms in Western Kenya found elevated levels of heavy metals in the soils with mean concentrations (mg kg⁻¹ dry weight) of 142.38, 59.12, 73.35, 116.27, 409.84 (dry season) and 144.22, 50.29, 72.14, 158.81, 368.83 (wet season) for Cr, Pb, Cu, Zn and Fe, respectively, compared with a control soil sample from an adjacent field wher...
Twelve lactating Holstein cows were utilized in a repeated switchback design to evaluate milk production and milk fat composition responses to wet corn distillers grains. Total mixed diets consisted of 31.4% corn silage, 18.4% alfalfa hay, and either 50.2% of a concentrate mix that contained mostly corn and soybean meal or 19.4% of a concentrate mix that contained mostly corn and 31.2% wet corn...
Sugarcane is one of the most important sugar crops in the world. Because of semi-arid climate and salinity of its cultivation area in our country, increasing salt tolerance of sugarcane is signifying. To achieve this goal determining salt tolerant cultivars and understanding salinity mechanisms in sugarcane are very important. This study was conducted to evaluate 8 commercial and promising su...
