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 main objective of this study was to determine the effects of plant growth promoter bacteria on biomass and yield of basil. The experiment was carried out as randomized complete blocks design with eight treatments and three replications at research field of Agriculture Company of Ran in Firouzkuh of iran in 2012 . The treatments were [1] Azotobacter chroococcum (A), [2] Azospirillum lipoferu...

The field experiment was conducted during Zaid season 2021-22 at Crop Research Farm, Department of Agronomy, Sam Higginbottom University Agriculture, Technology and Sciences, Prayagraj (U.P). soil the plot sandy loam in texture, nearly neutral reaction (pH 7.2), low organic carbon (0.48%), available N (171.48 kg/ha), P (13.6 kg/ha) K (215.4 kg/ha). treatments consisted three levels Gibberellic ...

Biofertilizer can be used to replace chemical fertilizer so that soil quality is maintained and pollution avoided. The study aimed determine the effect of biofertilizers with different compositions microorganisms on growth maize plants. research was carried out in a greenhouse. Maize plants were fertilized by two kinds microorganisms. first biofertilizer contained Azotobacter sp, Azospirillum R...

This review covers the history on Biological Nitrogen Fixation (BNF) in Graminaceous plants grown in Brazil, and describes research progress made over the last 40 years, most of which was coordinated by Johanna Döbereiner. One notable accomplishment during this period was the discovery of several nitrogen-fixing bacteria such as the rhizospheric (Beijerinckia fluminensis and Azotobacter paspali...

in order to evaluate the effects of beneficial free living bacteria (azotobacter chroococcum and azospirillum brasilense) compared to different nitrogen fertilizer levels on yield and yield components of barley (hordeum vulgare cv reyhan) a field experiment was conducted at research station college of agriculture, ferdowsi university of mashhad in 2007-2008. the experiment was arranged in a ran...
