Legume inoculants are products that introduce legume-specific rhizobia bacteria to the soil and promote process of biological nitrogen fixation. Guar (Cyamopsis tetragonoloba L. Taub.), also known as clusterbean, is a legume produced in semi-arid regions around world, primarily for industrial uses guar gum, but there only one commercial inoculant crop, which not available worldwide. The USDA-AR...

Illinois bundleflower (Desmanthus illinoensis (Michx.) Macmillan) has potential as a grain and forage legume for the American Midwest. Inoculant-quality rhizobia for this legume have been identified but not previously characterized. Rhizobia trapped from 20 soils in the natural range of the Illinois bundleflower had characteristics that placed them overwhelmingly within the species Rhizobium gi...

azospirillum is a well-studied genus of plant growth-promoting bacteria. phytohormone production by pgpr is considered as one of the effective factor to increase the tomato yield significantly. in order to study the effect of azospirillum inoculant on on growth characteristics and yields of tomato, three strain of azospirillum were isolated, identified, and purified from tehran suburb soils. to...

Although Azospirillum strains used in commercial inoculant formulations presents diazotrophic activity, it has been reported that their ability to produce phytohormones plays a pivotal role in plant growth-promotion, leading to a general recommendation of its use in association with regular N-fertilizer doses. In addition, a high variability in the effectiveness of Azospirillum inoculants is st...

This study was conducted to investigate the effects of adding citric acid residue (CAR) with or without lactic bacteria (LAB) Napier grass (Cenchrus purpureus; syn. Pennisetum purpureum) cv. Sumu No. 2 at ensiling on fermentation quality and aerobic stability resulting silage. Treatments included: Control (Napier forage additives); inoculated (Lactobacillus plantarum L. buchneri) 1 × 106 cfu/gf...

Abstract Salinity stress has become the major devastating constraint for rice growth. Halotolerant rhizobacterial nitrogen fixer (HRNF) was investigated increasing nitrogenase activity (NA), organic acid (OA), gibberellic (GA), and indole 3-acetic (IAA) productions, seedling growth, yield. Six N fixers were isolated using Ashby’s (Ab 1 , Ab 2 3 ) Okon’s media (Az Az ). Furthermore, bioassay car...

The diverse community of endophyte is a critical resource in enhancing plant growth. endophytic bacteria belong to larger group microorganisms that have their life-cycle partly or entirely inside the and are located intra inter-cellular spaces vascular tissue. Increasing nutritional content staple crops either through agronomic biofortification conventional plant-breeding strategies continue be...
