in order to study the qualitative and quantitative yield and some agronomic characteristics of sunflower (helianthus annus l.) in response to seed inoculation with pgpr under various levels of nitrogen fertilizer, a factorial experiment was conducted based on a randomized complete block design with three replications in field experimental university of mohaghegh ardabili during growing season o...

to evaluate the effects of plant growth promoting rhizobacteria (pgpr) such as azotobacter chroococcum, azospirillum lipoferom and brasilence and pseudomonas fluorescens and nitrogen fertilizer from urea source on yield and yield components of maize (zea mays l.) double cross hybrids (dc 370), a field experiment was carried out in a factorial experiment (5*3) in rcbd with 4 replications. bacter...

Area around the root zone i.e. rhizosphere is a rich environment for plant growth promoting bacteria (PGPR) which can be utilized in many way to improve the growth of crop and yield. In agriculture one of the limiting factors is providing plant nutrition particularly nitrogen and phosphorus to the crop. Different Plant-Growth Promoting Rhizobacteria (PGPR) such as Azospirillum, Azotobacter, Bac...

in order to investigate the effects of plant growth promoting rhizobacteria (pgpr) inoculation on the morphological traits of tarragon a factorial pot experiment, based on completely randomized design with four replications, were conducted in research field of horticulture department of mohaghegh ardabili university in 2010 - 2011. treatments consisted of inoculation with three species of rhizo...

Field research was conducted in Poland from 2019–2021 to determine the effect of bacteria Azospirillumlipoferum Br17 and Azotobacter chroococcum, as well companion red clover on total protein content yield grain spring barley cultivated a system organic agriculture. Two factors were examined field experiment: I. bacterial formulations: 1—control, 2—nitrogen-fixing (Azospirillumlipoferum Br17, c...

a study was conducted to evaluate the effects of plant growth promoting rhizobacteria (pgpr) inoculants including four strains of azotobacter chroococcum, azospirillum lipoferum, a. brasilense and pseudomonas fluorescence on dry matter accumulation of late maturing maize(zea mays l.) hybrids, sc704, sc700 and a promising single cross b73×k18. a factorial experiment was conducted in research fie...
