Root-knot nematodes are believed to be amongst the biological constraints causing severe damage and a great reduction in the productivity of okra. The purpose of this study was to apply organic matter and non-symbiotic nitrogen-fixing bacteria to minimize the addition of chemical fertilizers that constantly pollute the environment.  Experimental studies were conducted in the field for two summers to determine the effect of inoculations of non-symbiotic nitrogen-fixing bacteria, such as Azotobacter chroococcum and Azospirillum brasilense singly and in combinations, with different recommended doses of inorganic nitrogen as well as organic matter such as neem seed cake on the growth, yield, and organic parameters of the okra crop towards the management of plant-parasitic nematodes. The results show a significant reduction in nematode multiplication through soil application of nitrogen-fixing bacteria and neem seed cake along with different recommended doses of nitrogen inoculated plants. Azotobacter was found to be less effective than Azospirillum in agronomic parameters and nematode control. The most pronounced increases were observed in the yield and growth parameters such as plant height, fresh as well as dry weights, fruit weights/plant, number of total fruits/plant and primary branches, chlorophyll content, and ascorbic acid content when A. chroococcum and A. brasilense were added concomitantly in various combinations. Agronomic parameters such as NPK content in the plant as well as in residual soil increased considerably in almost all the combinations irrespective of these biofertilizers and neem seed cake. In conclusion, the combined application of a 100% recommended dose of nitrogen fertilizer along with Azospirillum and neem seed cake is recommended for better growth and yield of okra with better control of nematodal population.

Effectiveness forming and functioning of nitrogen-fixing systems created by soybean (Glycine max (L.) Merr.) and Tn5-mutants of Bradyrhizobium japonicum 646 with different symbiotic properties were studied in green house experiments. Inoculation of seeds by Tn5- mutants 107 and 113 with high virulence, but low activities, lead to decrease of the biometric properties and enhanced yield of plant seeds in comparison with control strains wild 646 and production 634б. Tn5- mutant 118-8 had the low nodulation and nitrogen fixing activities. Inoculation of seeds by high activity mutants 21-2 and 17-2 got reliable increase grain yield of plants in comparison with control. Consequently, this Tn5-mutants may to be used as perspective initial material for the next selection productive nodulate bacteria strains.

This experiment was carried out at the fields of the Department of Horticulture and Landscape Gardening, College of Agriculture, University of Baghdad, during the spring season of 2015 to study the effect of nitrogen fixing bacterial bio-fertilizers including Rhizobium phaseoli, Azotobacter  chroococcum, and Azospirillum brasilense and molybdenum on growth and yield of green beans. The experiment was conducted according to the randomized complete block design (RCBD) with three replications each included 11 treatments represent the interactions between nitrogen fixing bacteria strains, molybdenum solo application, molybdenum and bacteria strains interactions, in addition to the recommended nitrogen application and control treatment. Results were analyzed using the least significant differences (LSD) test at 5% level of significance. Results showed significant effect of the treatment that included all bacteria strains and Mo (T11) on increasing plant macro elements (N, P, and K) which gave 2.39%, 0.49%, and 2.92%, respectively and Fe and Mo concentrations of 269.67 mg.L-1 and 0.69 mg.L-1, respectively and protein percentage in the pods of 13.98%. in addition, treatment of both R. phaseoli  and A. chroococcum (T5) gave the most significant main root length of 36.56 cm while R. phaseoli  and A. chroococcum and Mo (T9) gave the largest root surface area of 115.00 cm2 and the highest number of root nods that reached 5.33 nod.plant-1. Moreover, T5 significantly increased plant height, leaf number, shoot dry weight, and pod’s length that reached 54.67 cm, 30.22 leaf.plant-1, 65.56 g.plant-1, and 13.62 cm, respectively. As for the T9, results showed significant increase in the number of pods per plant and plant yield of 51.61 pod.plant-1 and 262.03 g.plant-1, respectively.

Nitrogen Fixing Bacteria

Rhizosphere microbiomes which have been implicated to enhance plant growth and yield are modulated or influenced by a couple of environmental factors such as soil type, plant cultivar, climate change and anthropogenic activities. In particular, anthropogenic activity such as the use of nitrogen-based chemical fertilizers is associated with environmental destruction and this call for a more ecofriendly strategy to increase nitrogen level of agricultural land. This feat is attainable by harnessing nitrogen-fixing endophytic and free-living rhizobacteria. Rhizobium, Pseudomonas, Azospirillum and Bacillus have been found to have positive impacts on crops by enhancing both above and belowground biomass and could therefore play positive roles in achieving sustainable agriculture. Thus, it is needful to study these rhizosphere microbiomes with more sophisticated culture-independent technologies such as next generation sequencing (NGS) with the prospect of discovering novel bacteria with plant growth promoting traits. This review is therefore aimed at discussing factors that can modulate rhizosphere microbiomes with focus on the contributions of nitrogen fixing bacteria towards sustainable agricultural development and the techniques that can be used for their study.
