“…Both bacteria increased N uptake by fixing atmospheric N into a plant-available form. Organic and inorganic fertilizers combined with N-fixing bacteria help plants to expand their roots and absorb N from the soil [7,67,68]. According to Walia et al [69], the integrated nutrient management technique increased available N and P by 171.7 to 219.3 kg ha −1 , resulting in a positive influx of nutrients.…”

Nitrogen (N) availability and soil microbiota exert significant impacts on plant metabolic systems and yield. Different studies have indicated that yield and nitrogen use efficiency (NUE) of pearl millet (Pennisetum glaucum L.R.Br.) can be improved by the inoculation of N-fixing bacteria. However, the interactive effects of different N sources and bacteria inoculation on growth, productivity, and NUE of pearl millet have been less explored. Therefore, individual and interactive effects of different N sources (organic and inorganic) and bacteria inoculation on growth, productivity, and NUE of pearl millet were investigated in this study. Two different N sources, i.e., organic (farmyard manure) and inorganic (urea) alone or in 50% + 50% combinations (urea + FYM), were used to supply the recommended amount of N. Similarly, seeds were inoculated with two different N-fixing bacteria, i.e., endobacteria (Enterobacter sp. MN17) and rhizobacteria (Stenotrophomonas maltophilia FA-9). Urea + farmyard manure (FYM) and seed inoculation rhizobacteria improved soil attributes, yield-related traits, grain quality, NUE, and net economic returns. Soil porosity was significantly improved by seed inoculation with both bacteria and FYM application. Similarly, seed inoculation with rhizobacteria increased soil organic carbon by 45.45% and 34.88% during the 1st and 2nd year of the study, respectively. Urea + FYM application combined with rhizobacteria seed inoculation improved the number of grains per ear (23.49 and 23.63%), 1000-grain weight (5.76% and 7.85%), grain yield (23.19% and 25.0%), and NUE (33.83 and 48.15%). Similarly, grain quality was significantly improved by seed inoculation with both bacteria. Likewise, urea + FYM combined with rhizobacteria improved nitrogen use efficiency (NUE) by 33.83% and 48.15% in 2020 and 2021, respectively, compared to no N application and no seed inoculation. The highest economic returns (1506.4 and 1506.9 USD) were noted for urea + FYM application combined with rhizobacteria seed inoculation. Therefore, urea + FYM application combined with rhizobacteria (S. maltophilia FA-9) seed inoculation seemed a viable approach to improve grain yield, grain quality, NUE, and net economic returns of pearl millet.

“…(2013) revealed that PGPR-inoculated alfalfa plants generally show augmented tolerance compared to salt stress as a result of increased proline production and K uptake ( Younesi and Moradi, 2014 ). PGPRs contribute significantly to enhancing plant nutrient use efficiency and nutrient uptake ( Sharma et al., 2014 ; Khatri et al., 2016 ).…”

Salinity is a major environmental stress that limits crop production worldwide. It is well-understood that environmental adaptations, physiological and biochemical traits adjust salinity tolerance in plants, but imparting the knowledge gained towards crop improvement remain arduous. Utilizing the potentially of beneficial microorganisms present in the rhizosphere is an alternative strategy to improve crop production under optimal or stress conditions. The current study aims at examining the ability of plant growth-promoting rhizobacteria (PGPR) in improving coriander growth under salt stress condition. Coriander seeds were inoculated via dual culture of Azospirillum brasiliense and Azotobacter chroococcum , and therefore subjected to four levels of salt stress (0, 40, 80 and 120 mM NaCl) with three replications in a research greenhouse. Seventy-five days after sowing, when leaves fully developed, leaf samples were collected and the traits were measured. The results indicated that the dual inoculation improved chlorophyll a and b content, in comparison to the un-inoculated plants. The dual inoculation increased grain yield, stem fresh and dry weights by 11.6, 11.3 and 17.2%, respectively; it also enhanced total plant fresh and dry weights by 6.1 and 10.2%, respectively, as compared to control. As a result, the dual inoculation significantly improved catalase (CAT), but decreased ascorbate peroxidase (APX) and guaiacol peroxidase (GPX) enzymes activities, as compared to control plants. Salt stress significantly increased (CAT) activity in the leaves, whereas it resulted in significant reduction in (APX) and (GPX) activity, especially in inoculated plants. Furthermore, dual inoculation decreased Na and subsequently increased K concentration in coriander leaves comparing with untreated plants. Overall, these results indicate that the PGPRs has improved coriander growth under control as well as salt stress conditions. Thus, PGPR can could significantly contribute to solve the coriander plant production problems caused by high salinity.
