Plant growth-promoting rhizobacteria for orphan legume production: Focus on yield and disease resistance in Bambara groundnut

Abstract

Orphan legumes are now experiencing growing demand due to the constraints on available major food crops. However, due to focus on major food crops, little research has been conducted on orphan legumes compared to major food crops, especially in microbiome application to improve growth and yield. Recent developments have demonstrated the enormous potential of beneficial microbes in growth promotion and resistance to stress and diseases. Hence, the focus of this perspective is to examine the potential of plant growth promoting rhizobacteria (PGPR) to improve Bambara groundnut yield and quality. Further insights into the potential use of PGPR as a biological control agent in the crop are discussed. Finally, three PGPR genera commonly associated with plant growth and disease resistance (Bacillus, Pseudomonas, and Streptomyces) were highlighted as case studies for the growth promotion and disease control in BGN production.

Study on the mechanism of peanut resistance to Fusarium oxysporum infection induced by Bacillus thuringiensis TG5

“…PGPR strains ( Kumar et al, 2021 ; Samuel and Oluranti, 2022 ; Binnian et al, 2023 ), especially those with highly efficient promoting ( Madhusmita et al, 2021 ; Batoule and Risa, 2022 ) and biocontrol effects ( Amna et al, 2020 ; Mukesh et al, 2020 ), will undoubtedly occupy a dominant position in future production practices. Meanwhile, PGPR carrier ( Sang et al, 2020 ; Twinkle et al, 2021 ; Zhu et al, 2022 ) is one of the main factors restricting the promotion and application of microbial agents.…”

Assessment of Yield Stability of Bambara Groundnut (Vigna subterranea (L.) Verdc.) Using Genotype and Genotype–Environment Interaction Biplot Analysis

“…Research and development efforts are needed to establish modern crop management techniques and value chains to maximize the economic gains from Bambara groundnut production [12]. The crop is typically grown in regions with a dry or semi-arid climate [18,19]. It grows in a wide range of soil types, including sandy, loamy, and clay soils.…”
