“…Responses to the application of Mo in the peanut crop have been very variable in Brazil. Some studies have not reported increases in grain yield in the crop (Gericó et al., 2020; Rosolem & Caires, 1998; Soares‐Filho, Lazarini, Orioli‐Júnior, & Bernardes, 2020), although there has been a significant increase in nodulation and N uptake in peanut plants (Gericó et al., 2020). On the other hand, significant increases were obtained by Quaggio et al.…”

The use of plant growth–promoting rhizobacteria (PGPR) associated with rhizobia may improve biological N fixation, nutrient acquisition, and grain yield of the peanut (Arachis hypogaea L.). However, few studies have reported the effect of inoculation of rhizobia and PGPR in association with Mo in tropical soil conditions. This study examined the effectiveness of (co)inoculation with Bradyrhizobium spp. and/or Azospirillum brasilense and Mo application in improving the yield response of creeping peanut crop (‘RUNNER IAC 886’). The effects of rhizobacteria and Mo on nodulation, crop growth, chlorophyll content, and yield of peanut were investigated in a moderately acidic sandy soil (pH 5.0) from the Brazilian Cerrado during the 2016–2017 and 2017–2018 growing seasons. Four seed inoculation treatments (control [uninoculated seeds], inoculation with Bradyrhizobium spp. strains SEMIA 5079 and SEMIA 5080, inoculation with Azospirillum brasilense strains Ab‐V5 and Ab‐V6, and co‐inoculation of Bradyrhizobium spp. and Azospirillum brasilense) and two Mo levels (0 and 200 mg Mo kg−1 of seed) were studied. Results showed that the effects of the interaction between rhizobacteria and Mo application were not significant (p > .05) for all crop traits. Root nodulation, dry matter accumulation, and chlorophyll content were significantly greater in Mo‐treated peanut plants than control plants in both seasons. However, the response of crop grain yield was significantly greater (17.7%) in Mo‐treated plants only in the 2017–2018 season. Therefore, the improved root nodulation, crop growth, and chlorophyll content resulting from Mo application can lead to increased pod and grain yield in peanut. Inoculation with Bradyrhizobium spp. alone or combined with A. brasilense enhanced root nodulation, chlorophyll content, and peanut grain yield. Over two harvests, average peanut grain yield increased by 25.3 and 24.0% with inoculation of Bradyrhizobium spp. alone and combined with A. brasilense, respectively, compared with noninoculated plants. Due to lower cost and higher profitability, inoculation of Bradyrhizobium spp. alone is the most efficient practice for peanut cropping in sandy soils of the Brazilian Cerrado. Together with Mo application, these agricultural practices can be recommended for Brazilian peanut farmers.

“…Similarly, Mo acts as a cofactor for nitrogenase, which is responsible for biological nitrogen fixation. Insufficient Mo levels can lead to reduced nodulation and nitrogen fixation, as discussed by Gericó et al (2020). Co and Mo are essential for the vitamin B12 required synthesis for hemoglobin formation in nodules, therefore success N fixation (El-Sherpiny et al 2021).…”

This review aims to provide a comprehensive overview of the current state of knowledge on the effect of drought stress on the productivity of vegetable crops as well as the impact of applying melatonin to plants exposed to drought stress. Additionally, the study aims to investigate the beneficial role of rhizobium inoculant in nitrogen fixation using different solutions containing molybdenum, cobalt, and copper. By examining the existing literature, this review seeks to synthesize and analyze the key findings, trends, and gaps in research to date. The water scarcity crisis in Egypt (present status and future projections) will be highlighted as well as the effect of water deficit and plant performance, the role of melatonin as a hormone that suppresses the effects of water deficit on plants, biological N-fixation and stimulants of biological N-fixation. Additionally, this review will identify the significant challenges and opportunities in the field, with the ultimate goal of informing future research directions and practical applications.
