A field experiment was carried out in Zaid 2022 at the Department of Agronomy's Agricultural Research Farm Prayagraj (Uttar Pradesh). There are three planting geometries used 30 cm x 10 cm, 40 and 50 cm. nitrogen management treatments 50% Recommended Dose Nitrogen (RDN) through inorganic fertilizer, RDN th rough fertilizer combination with provided yard manure Azotobacter seed inoculation, fert...

plants are the most sources for cadmium enters to human food and this element in food regime may be a serious threat to human health. thus, the effect of azotobacter inoculum (azotobacter chroococcum), mycorrhiza fungi (glomus intraradaices) , zinc sulphate and urea on cadmium convertation and growth parameters of fenugreek medicinal plant (trigonella foenum gracum l.) in cadmium polluted soils...

Alfred Koch has given considerable attention to the subject of nitrogen fixation by bacteria as resulting from their symbiosis with alga~. Many others have also investigated various features of this problem. In spite of all this there are numerous questions which remain unsolved. The use of soil cultures for such studies is objectionable on account of the soil's complexity, its variety of flora...

in order to evaluate the response of quantitative and qualitative characteristics of the isabgol (plantago ovata frosk.) medicinal plant to separate and combined application of urea and biofertilizer an experiment was conducted in a randomized complete block design at the research farm of shahrekord university in 2011. the experimental treatments consisted of control (no urea and biological fer...

background and objectives: azotobacter is a diazotroph bacterium reported to possess various plant growth-promoting characteristics.the aim of this study was to isolate azotobacter strains capable of fixing nitrogen and effectively hydrolyzing both organic and inorganic pi compounds. materials and methods: in this study, soil samples collected from a diverse range of slightly alkaline soil type...

An Azotobacter vinelandii homolog to the Salmonella typhimurium mutS gene was discovered upstream of the fdxA gene. The product of this gene is much more similar to S. typhimurium MutS than either is to the HexA protein of Streptococcus pneumoniae. An A. vinelandii delta mutS mutant strain was shown to have a spontaneous mutation frequency 65-fold greater than that of the wild type.
