“…However, nodule number and dry weight decreased significantly with increased N rate (0, 50, 75, and 100 kg ha −1 ). A significant superiority of inoculation with Rhizobium over uninoculated treatments at all rates of N fertilization (50, 75, and 100 kg N ha −1 ) was also reported by Khaitov and Abdiev (2018). The authors found N at 75 kg N ha −1 combined with inoculation showed the highest seed yield and quality of chickpea.…”

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.

“…Many plant-associated bacteria can produce IAA in culture. The production of IAA, GA and Zeatin has also been reported in Bradyrhizobium japonicum [6]. The bioavailability of soil inorganic phosphorus in the rhizosphere varies considerably with plant species, soil nutritional status, presence of effective microorganisms and soil conditions.…”

The use of rhizobacteria for plant growth enhancement is decades old. Still, in this era of the 21st century, biofertilizers have become the need of the day due to the health and environmental concerns associated with chemical fertilizers and pesticides. Rhizobacteria strains were isolated from the rhizosphere of rice and wheat. The selected bacterial strains' nitrogen fixation, indole acetic acid (IAA) production, phosphorus solubilization, and antifungal activity were determined on morphological, biochemical, and molecular levels. Production of IAA ranged from 6 µg/ml to 29.33 µg/ml. Ethylene production (C2H4/hr) varied from 2 µmoles to 9.8 µmoles. Maximum Phosphorus Solubilization index (7), decrease in pH (4) and Solubilization % age (0.49) was observed in WM-2 (wheat microbe). Promising results were obtained concerning antifungal activity against Rhizoctonia solani and Fusarium sp. The effect of the potential PGPR strains on the germination of rice and wheat was significantly positive in Petri plates. In the case of rice, the highest shoot length (29.27 cm) was observed by inoculation with RPR-33 (Rice isolate), and the most increased root length (9.33 cm) was observed in the treatment inoculated with RPR-42. The highest shoot fresh weight (476.67 mg/plant) was recorded in the treatment inoculated with RPR-42. The maximum root weight was 170 mg/plant in the same treatment. For wheat, all recorded growth parameters were improved significantly by wheat microbe WM-5. All the PGPR isolates showed positive results for growth parameters of wheat and rice on inoculation. So, it is suggested that these PGPR isolates may be used in potential biofertilizers.

“…Gupta and Namdeo [18] showed that the inoculation of seeds with Rhizobium increased the yield of chickpea seeds by 9.6-27.9%. Khaitov and Abdiev [19] were observed that the seeds of chickpea inoculated with Rhizobium were significantly superior in yield over control treatments at all nitrogen fertilizer application rates. PSB might have helped to provide unavailable phosphorus from the soil that leads to more uptakes of nutrients and reflects better growth [10].…”

The availability of micronutrients in the niche defines the growth and yield parameters of chickpea. The present study was conducted to investigate the effect of different levels of biofertilizer with and without molybdenum on growth and seed yield of chickpea, at Seed Production Block, SGRR University, Dehradun, Uttarakhand. The experiment included seven treatment groups replicated thrice in Randomized Block Design. It was observed that all growth and seed yield parameters varied significantly with the application of different levels of biofertilizers with or without molybdenum. The observed results showed that all the plant growth parameters like plant height (54.67 cm), number of primary branches (5.34/ plant), number of pods per plants (64.00), fresh weight of plant (81.66 g) were maximum with treatment T6 (20 g Rhizobium+25 g PSB +0.3 g molybdenum/kg seeds). The number of nodules per plant (28.00) and 1000 seed weight (142 g) were recorded maximum with the application of treatment T7 (25 g Rhizobium + 30 g PSB + 0.3 g molybdenum per kg of seeds). The seed yield of chickpea was recorded maximum (15.67 q/ha) with the application of 20 g Rhizobium along with 25 g PSB and 0.3 g molybdenum per kg of seeds (T6). Thus, our findings indicate that, among all other treatments, the application of 20 g Rhizobium along with 25 g PSB and 0.3 g molybdenum per kg of seeds is suitable for higher seed yield of chickpea in Doon valley of Uttarakhand.
