“…Although the world's population is growing, most especially in developing nations, the local and international supply of food is being disrupted by the use of bio-resources for chemical manufacturing, production of energy, low-value addition, high postharvest losses, poor marketing systems, and inefficient distribution and other similar factors [3]. Farmers globally have concentrated most of their efforts on improving the yield of crops via extensive and intensive agriculture by implementing novel technologies and ideas [4,5]. Precision farming in combination with the application of nano-modified stimulants has boosted the current attempts.…”

Due to the deterioration of natural resources, low agricultural production, significant postharvest losses, no value addition, and a rapid increase in population, the enhancement of food security and safety in underdeveloped countries is becoming extremely tough. Efforts to incorporate the latest technology are now emanating from scientists globally in order to boost supply and subsequently reduce differences between the demand and the supply chain for food production. Nanotechnology is a unique technology that might increase agricultural output by developing nanofertilizers, employing active pesticides and herbicides, regulating soil features, managing wastewater and detecting pathogens. It is also suitable for processing food, as it boosts food production with high market value, improves its nutrient content and sensory properties, increases its safety, and improves its protection from pathogens. Nanotechnology can also be beneficial to farmers by assisting them in decreasing postharvest losses through the extension of the shelf life of food crops using nanoparticles. This review presents current data on the impact of nanotechnology in enhancing food security and reducing postharvest losses alongside the constraints confronting its application. More research is needed to resolve this technology’s health and safety issues.

“…In this regard, its consumption has been reported to cause vomiting, nausea, abdominal distention, and dyskinesia, especially in human beings and non-ruminant animals (Pulikkalpura et al, 2015). Therefore, utilization of this underutilized legume as animal feed requires a strategy to resolve the problem of high L-DOPA and fibre contents (Ajilogba et al, 2021). One of the innovative strategies that have been previously employed to modify the phytochemical composition of plants is nano-priming (do Espirito Santo Pereira et al, 2021).…”

“…The diversity of these microbial communities is driven by plant-microbe activities, such as an organic compound secreted by plants, as well as availability and quantity of nutrients released by microbes ( Ajilogba and Walker, 2020 ). PGPR also promote plant growth directly by producing phytohormones, such as Indole Acetic Acid (IAA), and indirectly by producing HCN, which is toxic against plant pathogen (biocontrol) and also makes phosphate available to plants ( Ajilogba and Babalola, 2019 ; dos Santos et al, 2020 ; Ajilogba et al, 2021 ; Kumar et al, 2021 ). Sometimes, they enhance iron chelation (siderophore production) and supply of nutrients, such as phosphorus (phosphate solubilization) and nitrogen (nitrogen fixation), to also promote plant growth.…”

Bambara Groundnut Rhizobacteria Antimicrobial and Biofertilization Potential

et al. 2022

Bambara groundnut, an underutilized crop has been proved to be an indigenous crop in Africa with the potential for food security. The rhizosphere of Bambara groundnut contains Rhizobacteria, with the ability to grow, adapt, and colonize their surroundings even in unfavorable conditions and have not been explored for their plant growth-promoting properties. The aim of this research was to determine the potential of rhizobacteria from Bambara groundnut soil samples as either biofertilizers or biocontrol agents or both to help provide sustainable agriculture in Africa and globally. Bambara groundnut rhizospheric soil samples were collected and analyzed for their chemical composition. Rhizobacteria isolates were cultured from the soil samples. Plant growth-promoting, antifungal activities and phylogenetic analysis using 16S rRNA were carried out on the isolates to identify the rhizobacteria. A 2-year field study planting was carried out to determine the effect of these rhizobacteria as biofertilizers for Bambara groundnut (Vigna subterranean). The study was carried out in a complete randomized block experimental design with three replications. All the isolates were able to produce ammonia and 1-aminocyclopropane-1-carboxylate, while 4.65, 12.28, and 27.91% produced hydrogen cyanide, indole acetic acid, and solubilized phosphate, respectively, making them important targets as biocontrol and biofertilizer agents. The field results revealed that treatment with rhizobacteria had significant results compared with the control. Characterization of selected isolates reveals their identity as B. amyloliquefaciens, B. thuringiensis, and Bacillus sp. These Bacillus isolates have proved to be plant growth-promoting agents that can be used as biofertilizers to enhance the growth of crops and consequent improved yield. This is the first time the rhizobacteria from the Bambara groundnut rhizosphere are applied as biofertilizer.
