BACKGROUND AND PURPOSE Intensive agriculture is practised in Taiwan, and compost application is very popular as a means of improving the soil physical properties and supplying plant nutrition. We tested the potential of inoculation with thermotolerant microorganisms to shorten the maturity and improve the quality of biofertilizer prepared by composting. METHODS Thermotolerant microorganisms w...

In order to prepare the multi-functional biofertilizer, thermo-tolerant phosphate-solubilizing microbes including bacteria, actinomycetes, and fungi were isolated from different compost plants and biofertilizers. Except Streptomycesthermophilus J57 which lacked pectinase, all isolates possessed amylase, CMCase, chitinase, pectinase, protease, lipase, and nitrogenase activities. All isolates cou...

in order to investigation the effect of different fertilization treatments on nutrient and essential oil contents in dragonhead drug (dracocephalum moldavica l.), an experiment was conducted in the station of agricultural research in urmia on 2008. treatments (nitroxin, barvar phosphate biofertilizer, biosulfur, nitroxin+ barvar phosphate biofertilizer, barvar phosphate biofertilizer + biosulfu...

Nitrogen fixation is mainly responsible for improvement of crop yield. In this regard, diazotrophs like Rhizobium, Azotobacter and Azospirillum are important as they enrich nitrogen nutrition in N-deficient soils. Of these, Azotobacter promotes plant growth as well as nitrogen fixation. Thus technology has been developed for making use of Azotobacter biofertilizer for nitrogen and non-nitrogen ...

objective: many agronomic practices may need to be adjusted to maximize yield and quality of sugar beet. thus agronomic package must be always modified. this sutdy was laid out for evaluation of changes in carbohydrates and sugar yield in sugar beet (beta vulgaris l.) under different biofertilizers and irrigation closed time at dorud region of iran, during 2013. methods: the experimental design...

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...

BACKGROUND: Nitrogen is a basic plant component, playing a decisive role in the intensification of plant production. Bio-fertilizers play a very significant role in improving soil fertility by fixing atmospheric nitrogen, both, in association with plant roots and without it, insoluble soil phosphates and produces plant growth substances in the soil. OBJECTIVES:</s...
