“…Inoculation with A. brasilense and P. fluorescens did not increase root length of wheat plants under adequate soil moisture, but increased root and shoot biomass accumulation, although it did not affect grain yield [22]. The inoculation of dual-purpose wheat (pasture and grain production) plants with A. brasilense provided an increase in the production of tillers and leaf blades [23]. Under drought conditions, the effects of A. brasilense have been observed on physiological variables such as turgor maintenance or protection against oxidative stress [24,25].…”

Aims:To investigate the effect of inoculation and co-inoculation of Pseudomonas spp. and Azospirillum brasilense on the morphophysiological characters of wheat (Triticum aestivum L.) under drought stress conditions. Study Design: A randomized complete block design was used in a split plot scheme with four replicates. The plots consisted of irrigated and drought conditions. The subplots consisted of control (without inoculation), inoculation of Pseudomonas spp., inoculation of A. brasilense and coinoculation of Pseudomonas spp. + A. brasilense. Liquid inoculant was used for two bacteria. Place and Duration of Study: Agricultural Experimental Area of the Federal University of Santa Catarina, Campus of Curitibanos, SC, Brazil, between July and October 2018. Methodology: Inoculation was performed at the time of sowing. Water deficit was characterized by irrigation suppression after plant emergence, considering a 25-day period without significant rainfall. Fioreze et al.; JEAI, 42(2): 1-7, 2020; Article no.JEAI.53070 2 At the end of the water restriction period, SPAD (Soil Plant Analysis Development) index and morphologic parameters of wheat plants was determined. Results: Drought stress decreased dry matter accumulation of wheat plants, in terms of number of tillers, above ground dry matter and root-shoot ratio. Inoculation or co-inoculation with Pseudomonas spp. and A. brasilense did not affect plant growth. Under drought stress, SPAD index was higher in plants co-inoculated with Pseudomonas spp. and A. brasilense. Conclusion: Although maintains SPAD index of wheat plants under drought stress, inoculation and co-inoculation with Pseudomonas spp. and A. brasilense do not influence the morphological characters of wheat plants.

“…It is, however, evident that the application of only bio-fertilizers does not give the maximum boost to crop productivity, and, thus, partial substitution of mineral fertilizer with bio-fertilizer is suggested to achieve the best results from the cropping system (Habiba et al, 2018). Studies evaluating the application of PGPB as seed inoculants have been mostly focused on genotypes exclusively recommended for grain production, with few researches on dual-purpose crops (Quatrin et al, 2019). In this regard, research results reported variations in the yield and quality of dual-purpose wheat, oat and sorghum (Bilal et al, 2017;Patel et al, 2018;Quatrin et al, 2019), inoculated with bio-inoculants according to the rate of applied N fertilizer.…”

The utilization of dual-purpose cereals is encouraged in the Mediterranean environments to fill a feed gap during the winter season. Triticale is a promising dual-purpose crop for forage and grain production. Studies on the variations in productivity and quality of dual-purpose triticale under variable fertilization management are scarce. This study was carried out during winter 2018/2019 and 2019/2020, in Northern Egypt, to evaluate the performance of triticale grown in dual-purpose and grain-only production systems under variable mineral N (mN) rates (zero, 25, 50, 75% of the recommended), accompanied with Azotobacter chroococcum (AC) seed inoculation, as well as 100% mN application without AC. The application of 50% mN with AC seed inoculation resulted in an average of 7.23, 7.27 t ha-1, forage and grain yields, respectively. Moreover, forage and grain crude protein reached 125.57, and 200.60 g kg-1, respectively. Forage fiber fractions were non-significantly variable among the fertilizer treatments. Azotobacter chroococcum seed inoculation, thus, allowed for the reduction of the used amount of mN to 50% without sacrificing the forage and grain yields and protein content. In the dual-purpose system, an average of 7.23 t ha-1 forage yield was obtained with little reduction in the grain yield (19% reduction in average). Meanwhile, grain CP content was higher in dual-purpose system (201.38 g kg-1) than in grain-only system (182.98 g kg-1). In similar conditions to the current study, it is recommended to expand the production of dual-purpose triticale in the winter while reducing mN fertilizer rate to 50% in combination with AC seed inoculation.

“…Nitrogen fixing bacteria is generally well known for the ability to fix atmospheric nitrogen and is widely used worldwide for inoculating legumes. However, the ability to release phosphorus has also been found in some nitrogen fixing genera such as Rhizohium, Bradyhizobium, and Sinorhizobium [11][12].…”

The current research was aimed at assessing the yield and grain quality of spring barley inoculated during sowing with microbiological fertilizers “Azotovit” and “Phosphatovit” on leached chernozem in the forest-steppe conditions of the Middle Volga region at a dose of 2 l/t. These microbiological fertilizers “Azotovit” and “Phosphatovit” used for seed inoculation had practically no effect on field germination and safety of spring barley. With the pre-sowing treatment of Azotovit seeds, the sparseness of crops averaged 11.1%, with the treatment of Phosphatovit seeds - 9.5%, and with the treatment of both Azotovit and Phosphatovit seeds amounted to 7.4% at 15.7% on control. The use of the fertilizers led to an increase in the productivity of spring barley seeds up to 3.25 t/ha. The highest grain yield was obtained with the combined use of “Azotovit” and “Phosphatovit”, where the yield was higher than in the control by 0.36 t/ha (12.3%). The number of seeds per 1 crop and the mass of seeds per 1 crop, with the combined use of “Azotovit” and “Phosphatovit”, on average over two years of research increased by 2.8 pcs and 0.108 g, relatively, compared with the control group. Grain quality indicators have improved. Treatment of seeds of spring barley before sowing with micronutrient fertilizers increased the weight of 1000 grains by 3.5 g in comparison with the control group; increased the grain size by 2.7-13.1 g/l. The smallest increase in the grain productivity was observed in the case with seed treatment before sowing “Azotovit” and “Phosphatovit” by 2.7 g/l and 3.9 g/l, relatively, and the greatest increase in the grain productivity was obtained in the case with the combined use of both fertilizers by 13.1 g/l. This indicates a positive effect from the use of microbiological fertilizers in the barley cultivation technology.
