introduction: use of unbalanced chemical fertilizers especially p, having low absorption efficiency and low solubility compounds with soil components, has resulted in the production and use of bio-fertilizers (17, 23 and 29). bio-fertilizer is a preservative material consisting of one or several specific beneficial micro-organisms or their metabolic products used to supply plant nutrients and d...
–Phosphorus is one of the most vital macronutrients required for the growth and development of plants. A large number of microorganisms present in the rhizosphere are known to solubilize and make available the insoluble phosphorus in the available form to the plants. A total of fifty phosphate solublizing bacterial colonies were isolated on the Pikovskaya’s (PKV) agar medium, containing insolub...
native phosphate solubilizing bacteria (psb) were isolated from four areas (ankober, keyt, mehalmeda and molale) of ethiopia to study their effect on releases of soluble phosphorus from insoluble p sources. the highest bacterial number was found at keyt (2.6103 g-1soil) and the least at molale (15 g-1soil). five efficient psb were selected for further study based on their ability in forming a ...
One hundred thirty-four putative Bacillus isolates were recovered from soybean rhizosphere soils of Nimar region to select effective zinc solubilizers for increased assimilation of zinc (Zn) in soybean seeds. These isolates were screened in vitro for zinc-solubilization ability on Tris-minimal agar medium supplemented separately with 0.1% zinc in the form of zinc oxide, zinc phosphate, and zinc...
in order to study the effect of mineral nutrient and salicylic acid on the fruit yield and yield components of coriander, a study was conducted in experimental field of gorgan university during 2007. the experiment was laid out in randomized block design with ten treatments (salicylic acid, nitrogen, phosphorus, potassium, magnesium, zinc, iron, boron, molybdenum and control) in three replicati...
Background and objectives: Plant properties and forage value of lathyrus rotundifolius, was assessed in Namin rangeland. Persian everlasting pea is belonged to legume family and it is a wild plant that grow at Heyran and Fandoghlo region in Ardebile province of Iran. Based on local residents experience, they consider the forage of this plant as one of the best forage and collect it for livestoc...
The present study demonstrates the use of mixed co solvency in the enhancement of solubility and estimation of ketoprofen, practically water insoluble dug and thus precludes the use of organic solvents. The selected solubilizers were sodium citrate (15%), PEG 400 (8%) and polyvinyl pyrolidine (7%). Beer’s law was obeyed in the concentration range of 2-20μg/ml at wavelength of 256nm. The solubil...
This thesis explores the potential of zinc, cobalt, and phosphorus to influence primary production in the subarctic North Pacific, the Bering Sea, and the North Atlantic Ocean. In the North Pacific and Bering Sea, total zinc concentrations were measured along a near-surface transect and in selected deep profiles. Zinc speciation was also measured with a novel anodic stripping voltammetry method...
The isolation of phosphate solubilizing bacterial strains exhibiting high ability to solubilize soil phosphorus is a matter of great interest with high applicability. The use of phosphate solubilizing bacteria as inoculants simultaneously increases phosphate uptake by the plant and increase crop yield. Strains from the genera Pseudomonas, Bacillus and Rhizobium species are among the most powerf...
In order to clarify the mechanism that zinc and phosphorus elements entering the micro-arc oxidation (MAO) coatings developed on Ti-6Al-4V alloys, anodic coatings containing different zinc and phosphorus were fabricated using an orthogonal experiment of four factors with three levels in an electrolyte containing EDTA-ZnNa₂, KOH, and phytic acid. Surface morphology, element composition, chemical...
