“…In another study, an amount of 40 kg N·ha −1 was used as a starter N-dose by [42], when they measured the field performance of rhizobial inoculants for some important legumes (lentils, soybeans, faba beans, and peanuts) in Egypt under both clay loam Nile Delta soils and virgin sandy soils. Our results are consistent with previous studies which have reported that the application of an amount of N fertilizer enhances nodulation of different legume crops [33,43,44].…”

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.

“…These results indicate that the inoculated isolate could fulfill the N needs of the plant in addition to the native soil total N at Fedis and Haramaya site as previously observed by Mnasri et al (2007). The result obtained in these three sites agreed with previously reported by Daba and Haile (2000) who found that starter N with Rhizobium inoculation recommended to improve nodulation and yield of common bean in eastern Ethiopia. The application of a small amount of fertilizer N (15-30 kg N ha −1 ) enhances nodulation of different legume crops (da Silva et al 1993;Tsai et al 1993b;Hungria et al 2003).…”

“…The present study also indicated the positive effect of Rhizobium inoculation on AE-N at low rates of N application (i.e., less than 40 kg N ha enhances productivity and nodulation of common bean (Tsai et al 1993b;Daba and Haile 2000;Hungria et al 2003). At Babillae site, the highest AE-N (10.16 and 11.6 kg kg −1 ) from inoculated and uninoculated treatments was obtained at 40 and 20 kg N ha −1 , respectively.…”

Background: Due to common bean derives lower nitrogen (N) from symbiotic N 2 -fixation, it requires N either from inorganic fertilizer or soil N. Field experiments were conducted at four locations to evaluate the effect of Rhizobium leguminosarum bv. phaseoli inoculation on agronomic efficiency of N of common bean var. Dursitu major growing areas of eastern Ethiopia. ) and two inoculation treatments (uninoculated and inoculated) were factorially combined and laid out in randomized completely block design, replicated three times. . The highest AE-Ns at Babillae, Fedis and Haramaya sites were obtained from 20 kg N ha −1 applied with Rhizobium inoculation while 40 kg N ha −1 supplied with Rhizobium inoculation at Hirna site. Regardless of experimental sites, inoculation improved AE-N. A positive relationship between AE-N and NDW was also observed in all experimental sites. Significant increase in grain yield with increasing rates of N application was also observed. Methods Results Conclusion:Hence, it can be concluded that inoculation is recommendable to increases the efficient utilization of applied Mineral N.

“…Soybean seed yield in 2017/2018 was generally low compared to 2016/17 but N application and seed inoculation had positive effects, and their combined application at N rate 27 kg ha −1 increased yield by 73.2 and 128.2% improvement over unfertilized but inoculated and over control, respectively. Daba and Haile (2000) suggested that inoculation of strain and starter N (23 kg ha −1 ) fertilizer gave a significantly higher grain yield, nodule number, and dry matter yield in soils of Eastern Ethiopia. These results are consistent with those of a field study in Brazil Hungria et al (2006) that reported low rates of symbiotic BNF in soybean with relatively high N fertilizer.…”

Background: For manipulating N 2 fixation and improve the N benefits to agricultural legumes, there is a need to reduce the inhibitory effect of applied N on Rhizobia inoculant. The optimum level of inorganic N as starter fertilizer with inoculation of Rhizobia is essential to increase the production of legumes in smallholder farmers. However, the effect of inorganic N level which should be used by farmers with an inoculation to increase the production of soybean is not yet well known in soils of western Ethiopia. Therefore, the study conducted to determine the amount of starter N application which could enhance N 2 fixation and soybean seed yield using Rhizobial inoculation and different nitrogen doses. Methods: Six levels of nitrogen fertilizer (0, 9, 18, 27, 36, and 54 kg N ha −1) and two levels of inoculation (inoculated (1) and un-inoculated (0)) were arranged using split-plot RCBD with three replications. Result: Seed inoculation with Rhizobia was significantly superior over un-inoculated treatments. Both rhizobia inoculation and N rates applied alone increased nodulation and yield of soybean, however, their combination further increased nodulation, growth performance, and seed yield and yield traits of soybean. Although nodulation parameters showed inconsistent results across cropping seasons, N application improved nodulation and shoot dry weight and interacted positively with inoculation across locations. Increasing rates of N from zero up to 18 kg ha −1 increased nodule number and dry weight but further increase of N reduced nodulation. Application of N at 18 kg ha −1 increased nodule number and dry weight by 98.3 and 115.0%, respectively over un-fertilized control as well as by 61.0 and 58.0%, respectively over the greatest N rate (54 kg N ha −1). The highest seed yield of soybean was obtained when inoculation applied with N at 18 and 27 kg ha −1 in 2016/17 and 2017/18, respectively across locations. However, seed yield in the 2016/17 cropping season was much higher than 2017/18. In 2016/17 and 2017/18, inoculation together with N at 18 kg ha −1 increased grain yield by 75.0 and 76.8% compared with for the control plants, 50.7 and 31.6% compared with inoculation alone, respectively. In both cropping seasons, the un-inoculated plants had shown a trend that an increase in seed yield with increased N rate. Conclusion: Application of fertilizer N up to 18 kg ha −1 may be an optimum rate for effective nodulation and enhanced N 2 fixation and thereby improved soybean yield. The present results demonstrate the potential of improving soybean nodulation, growth, and seed yield profitability using Rhizobia inoculant together with starter N at low N Nitisols soils of Western Ethiopia.
