“…Interestingly, the use of PGPB is a potent and upcoming method to ensure sustainable agriculture without depleting natural resources [ 221 , 222 ]. The introduction of successful PGPB to soil ecosystems improves soil’s physical (e.g., reducing sodicity and bulk density, improving water infiltration rate, and increasing porosity and aeration) and chemical (e.g., reducing acidity) properties [ 223 ]. However, before PGPB can be applied to the environment, there are several safety standards and qualities that should be fulfilled [ 224 , 225 ].…”

As a major food crop, rice (Oryza sativa) is produced and consumed by nearly 90% of the population in Asia with less than 9% produced outside Asia. Hence, reports on large scale grain losses were alarming and resulted in a heightened awareness on the importance of rice plants’ health and increased interest against phytopathogens in rice. To serve this interest, this review will provide a summary on bacterial rice pathogens, which can potentially be controlled by plant growth-promoting bacteria (PGPB). Additionally, this review highlights PGPB-mediated functional traits, including biocontrol of bacterial rice pathogens and enhancement of rice plant’s growth. Currently, a plethora of recent studies address the use of PGPB to combat bacterial rice pathogens in an attempt to replace existing methods of chemical fertilizers and pesticides that often lead to environmental pollutions. As a tool to combat bacterial rice pathogens, PGPB presented itself as a promising alternative in improving rice plants’ health and simultaneously controlling bacterial rice pathogens in vitro and in the field/greenhouse studies. PGPB, such as Bacillus, Pseudomonas, Enterobacter, Streptomyces, are now very well-known. Applications of PGPB as bioformulations are found to be effective in improving rice productivity and provide an eco-friendly alternative to agroecosystems.

“…Frequently, compost is used as organic fertilizer to replenish nutrients, organic matters to arable soil, or as growing substrate. Several studies have demonstrated that compost fertilization can improve not only soil fertility ( Ding et al, 2019 ; Singh et al, 2020 ; Wu et al, 2020 ) but also several ecological services in agroecosystems including mitigation of nitrate leaching ( Kramer et al, 2006 ; Han et al, 2017 ; Picariello et al, 2020 ) and maintenance of plant health ( Kalbani et al, 2016 ). It has been demonstrated that compost is suppressive to several soil-borne diseases such as Fusarium , Verticillium , or Phytophthora ( Lang et al, 2012 ; Wu et al, 2017 ; Bellini et al, 2020 ).…”

Compost is frequently served as the first reservoir for plants to recruit rhizosphere microbiome when used as growing substrate in the seedling nursery. In the present study, recruitment of rhizosphere microbiome from two composts by tomato, pepper, or maize was addressed by shotgun metagenomics and 16S rRNA amplicon sequencing. The 16S rRNA amplicon sequencing analysis showed that 41% of variation in the rhizosphere bacterial community was explained by compost, in contrast to 23% by plant species. Proteobacterial genera were commonly recruited by all three plant species with specific selections for Ralstonia by tomato and Enterobacteria by maize. These findings were confirmed by analysis of 16S rRNA retrieved from the shotgun metagenomics library. Approximately 70% of functional gene clusters differed more than sevenfold in abundance between rhizosphere and compost. Functional groups associated with the sensing and up-taking of C3 and C4 carboxylic acids, amino acids, monosaccharide, production of antimicrobial substances, and antibiotic resistance were over-represented in the rhizosphere. In summary, compost and plant species synergistically shaped the composition of the rhizosphere microbiome and selected for functional traits associated with the competition on root exudates.

“…The organic fertilizers improve soil fertility, physical properties viz. declining sodicity, reducing bulk density, water infiltration rate, increasing porosity and aeration, improving saline water leaching and chemical properties, that is, decreasing acidity [Singh et al, 2020]. Moreover, organic fertilizers contain many nutrients necessary to plants, in addition to raising the organic matter content of soil, thus improving its physical and chemical properties, which positively affects the yield and improves crop quality [Dongmei et al,201]).…”

Chives (Allium schoenoprasum L.) is a perennial plant [Singh et al., 2018], which was recently introduced to the Egyptian market. It belongs to the Alliaceae family and the Allium genus, which contains many important plants such as garlic, leeks, shallots, and onion [Yoldas et al., 2019]. Because it is has medicinal and edible functions [Jiang-xue et al., 2018], it is widely cultivated around the world. The plant is distinguished in taste and rich in sulfur compounds that can be used for its antimicrobial properties [Krishnan and Nair, 2016]. Ghasemian et al., [2018], found that; the A. schoenoprasum extracts exhibited higher activity against S. aureus and B. cereus strains. Moreover, numerous studies indicate that the plant has antioxidant properties [Lim, 2015]. In a study conducted in 2017, it was reported that; a chives plant could be used as an antioxidant [Bezmaternykh et al., 2017]. Another study, confirmed that; the A. schoenoprasum L. leaves can be considered as a potential antioxidant [Pesantes et al., 2019]. Moreover, chives are a nutrient-dense food, which contains thiamin, zinc and phosphorus; they are a very good source of fibers, vitamins, and minerals such
