to study the effect of biofertilizers and manure on yield and yield components of barley (hordeum vulgare) an experiment was conducted at research farm of university of zabol, iran in 2012 cropping season. experimental treatments were arranged in a factorial design based on a randomized complete block design with three replications. treatments were three manure levels (control, 20 ton/h-1, 30 t...

The tetramethyl-p-phenylenediamine oxidase reaction commonly used in the Kovacs oxidase test was quantitatively estimated for various Neisseria species employing standardized resting cell suspensions. This genus of microorganisms exhibited very high tetramethyl-p-phenylenediamine oxidase rates comparable to that of Azotobacter and Pseudomonas, and this reaction was found to be a valid measureme...
