“…This present study also confirms that the common bean-rhizobia symbiosis was not satisfactory to fulfill the N needs as it has been previously observed by Fesonko et al [50]. Contrary to this, Denton et al [40] showed that improvement of shoot N increased the grain yield of faba bean by 1 Mg ha −1 in soil having low rhizobial population. This indicates that biological N 2 fixation alone is not a sufficient N requirement of common bean to get the local attainable yield in the prevailing environmental condition.…”

Background: Supplement with inorganic N application is essential to improve the common bean production in sub-Saharan Africa. However, the influence of indigenous rhizobial population on the inorganic N requirement with Rhizobium inoculation to secure sustainable way of common bean production system is not well known. The effect of different rates of N application either alone or in combination with Rhizobium inoculation on the nodulation, yield and yield traits of common bean cultivated in soils with different rhizobial population were conducted.Methods: Twelve treatments were produced by factorially combined six levels of N fertilizer (0, 20, 40, 60, 80 and 100 kg N ha) and two Rhizobium inoculation treatments (inoculated and uninoculated). The treatments were laid out in randomized completely block design and all treatments were replicated three times.Result: Regardless of soil types, nodule number and nodule dry weight decreased with increasing rates of N application. 20 kg N ha −1 both alone and in combination with Rhizobium inoculation resulted in the largest nodulation in all soil types. The largest nodulation were induced in soil with large rhizobial population. Rhizobium inoculation significantly (P < 0.05) improved yield and yield traits of common bean. Moreover, our result revealed that the largest values of investigated traits were observed in inoculated treatment, as compared to the corresponding N rates of uninoculated treatments. The 20, 100 and 40 kg N ha −1 treatments resulted in significantly greater plant total tissue N at soil types with small, medium and large rhizobial population, respectively, as compared to unfertilized control. The highest total biomass yield (TBY) and grain yield (GY) at soil types with small and medium rhizobial population were obtained by the 100 kg N ha −1 treatment in combination with Rhizobium inoculation, while 20 and 40 kg N ha −1 applications produced the greatest TBY and GY, respectively, in soil with large rhizobial population. Conclusion:These results indicate that N requirement is varied based on rhizobial population and effectiveness of native rhizobia in N 2 fixation.

“…It has been shown that number of native rhizobia had a detrimental impact on productivity of above ground dry biomass [39]. Denton et al [40] found increased shoot biomass production with increased Rhizobium inoculation rate. In all soil types, the lowest SDW were produced for the control treatments (uninoculated and unfertilized).…”

“…The success of legume grain crops is dependent on their capacity to form effective nitrogen-fixing symbioses with root-nodule bacteria. However, many soils may do not have adequate amounts of native rhizobia in terms of number, quality, or effectiveness to enhance biological nitrogen fixation [29]. Rhizobium-legume association can be manipulated, through inoculation under N-limiting field conditions, to improve crop production easily and inexpensively [35].…”

“…The use of Rhizobium inoculants in legumes is the oldest agro-biotechnological application [37]. Several reports demonstrated significant improvement of yield and yield components in faba bean with Rhizobium inoculation [29,[38][39][40].…”

“…In such cases, the reliance on soil rhizobia as the sole source of inoculants can restrict legume yields [27,28]. Therefore, research on the impact of legume inoculation with efficient rhizobial strains can assist in defining the potential of inoculation to improve legume yields and increase the contribution of legume fixed N to the agriculture system [29].…”

Improvement of Faba Bean Yield Using Rhizobium/Agrobacterium Inoculant in Low-Fertility Sandy Soil

Soil fertility is one of the major limiting factors for crop's productivity in Egypt and the world in general. Biological nitrogen fixation (BNF) has a great importance as a non-polluting and a cost-effective way to improve soil fertility through supplying N to different agricultural systems. Faba bean (Vicia faba L.) is one of the most efficient nitrogen-fixing legumes that can meet all of their N needs through BNF. Therefore, understanding the impact of rhizobial inoculation and contrasting soil rhizobia on nodulation and N 2 fixation in faba bean is crucial to optimize the crop yield, particularly under low fertility soil conditions. This study investigated the symbiotic effectiveness of 17 Rhizobium/Agrobacterium strains previously isolated from different Egyptian governorates in improving the nodulation and N 2 fixation in faba bean cv. Giza 843 under controlled greenhouse conditions. Five strains that had a high nitrogen-fixing capacity under greenhouse conditions were subsequently tested in field trials as faba bean inoculants at Ismaillia Governorate in northeast Egypt in comparison with the chemical N-fertilization treatment (96 kg N·ha −1 ). A starter N-dose (48 kg N·ha −1 ) was applied in combination with different Rhizobium inoculants. The field experiments were established at sites without a background of inoculation under low fertility sandy soil conditions over two successive winter growing seasons, 2012/2013 and 2013/2014. Under greenhouse conditions, inoculated plants produced significantly higher nodules dry weight, plant biomass, and shoot N-uptake than non-inoculated ones. In the first season (2012/2013), inoculation of field-grown faba bean showed significant improvements in seed yield (3.73-4.36 ton·ha −1 ) and seed N-yield (138-153 Kg N·ha −1 ), which were higher than the uninoculated control (48 kg N·ha −1 ) that produced 2.97 Kg·ha −1 and 95 kg N·ha −1 , respectively. Similarly, in the second season (2013/2014), inoculation significantly improved seed yield (3.16-4.68 ton·ha −1 ) and seed N-yield (98-155 Kg N·ha −1 ) relative to the uninoculated control (48 kg N·ha −1 ), which recorded 2.58 Kg·ha −1 and 80 kg N·ha −1 , respectively. Interestingly, faba bean inoculated with strain Rlv NGB-FR 126 showed significant increments in seed yield (35%-48%) and seed N-yield (34%-49%) compared to the inorganic N fertilizers treatment (96 kg N·ha −1 ) over the two cropping seasons, respectively. These results indicate that inoculation of faba bean with effective rhizobial strains can reduce the need for inorganic N fertilization to achieve higher crop yield under low fertility soil conditions.
