To fulfill the demand of increased population it is very essential to enhance crop productivity with precise inputs. Non-judicious application of inorganic fertilizers and other agrochemicals is degrading soil health, creating environmental pollution and also contributing to climate change. Nowadays, people became more aware towards health risks and demand for quality foods with less chemical residues is increasing as there is a progression of demand for organic products. But it is very difficult to produce adequate quantity of organic foods for the raised population in the developing countries as per standard organic practices. That’s why judicious use of inorganic fertilizers, organic manures and biofertilizers is required to supply nutrients to crops. Plant growth promoting rhizobacteria (PGPR), such as Rhizobium inoculation in groundnut (a major oilseed crop) can boost crop growth and enhance yield in a sustainable manner. Further, Rhizobium has multifaceted advantages in crop nutrient uptake and soil quality improvement. The article described the role of PGPR as well as Rhizobium in growth and productivity of groundnut towards production sustainability.

AbstractPromoting crop diversification in European agriculture is a key pillar of the agroecological transition. Diversifying crops generally enhances crop productivity, quality, soil health and fertility, and resilience to pests and diseases and reduces environmental stresses. Moreover, crop diversification provides an alternative means of enhancing farmers’ income. Camelina (Camelina sativa (L.) Crantz) reemerged in the background of European agriculture approximately three decades ago, when the first studies on this ancient native oilseed species were published. Since then, a considerable number of studies on this species has been carried out in Europe. The main interest in camelina is related to its (1) broad environmental adaptability, (2) low-input requirements, (3) resistance to multiple pests and diseases, and (4) multiple uses in food, feed, and biobased applications. The present article is a comprehensive and critical review of research carried out in Europe (compared with the rest of the world) on camelina in the last three decades, including genetics and breeding, agronomy and cropping systems, and end-uses, with the aim of making camelina an attractive new candidate crop for European farming systems. Furthermore, a critical evaluation of what is still missing to scale camelina up from a promising oilseed to a commonly cultivated crop in Europe is also provided (1) to motivate scientists to promote their studies and (2) to show farmers and end-users the real potential of this interesting species.

Vegetable cultivation is a promising economic activity, and vegetable consumption is important for human health due to the high nutritional content of vegetables. Vegetables are rich in vitamins, minerals, dietary fiber, and several phytochemical compounds. However, the production of vegetables is insufficient to meet the demand of the ever-increasing population. Plant-growth-promoting rhizobacteria (PGPR) facilitate the growth and production of vegetable crops by acquiring nutrients, producing phytohormones, and protecting them from various detrimental effects. In this review, we highlight well-developed and cutting-edge findings focusing on the role of a PGPR-based bioinoculant formulation in enhancing vegetable crop production. We also discuss the role of PGPR in promoting vegetable crop growth and resisting the adverse effects arising from various abiotic (drought, salinity, heat, heavy metals) and biotic (fungi, bacteria, nematodes, and insect pests) stresses.

Bolivian Rainbow Chili is one of the ornamental chili varieties which is unique in the form of its colorful fruit color. The vegetative growth of ornamental chilies requires additional nutrients and the role of microorganisms to obtain optimal growth. This study aims to determine the optimal growth of rainbow chilies using the application of PGPR biological fertilizer, a combination of PGPR biological fertilizer and NPK synthetic fertilizer, as well as a combination of PGPR biological fertilizer and compost organic fertilizer. This research was conducted with a completely randomized design (CRD). The data obtained were then analyzed by ANOVA and continued with the LSD test and Duncan’s test at the 5% test stage. The results showed that the combination treatment of PGPR and compost or PGPR and NPK provided optimal vegetative growth compared to single PGPR treatment.

Climate change imposes biotic and abiotic stresses on soil and plant health all across the planet. Beneficial rhizobacterial genera, such as Bacillus, Pseudomonas, Paraburkholderia, Rhizobium, Serratia, and others, are gaining popularity due to their ability to provide simultaneous nutrition and protection of plants in adverse climatic conditions. Plant growth-promoting rhizobacteria are known to boost soil and plant health through a variety of direct and indirect mechanisms. However, various issues limit the wider commercialization of bacterial biostimulants, such as variable performance in different environmental conditions, poor shelf-life, application challenges, and our poor understanding on complex mechanisms of their interactions with plants and environment. This study focused on detecting the most recent findings on the improvement of plant and soil health under a stressful environment by the application of beneficial rhizobacteria. For a critical and systematic review story, we conducted a non-exhaustive but rigorous literature survey to assemble the most relevant literature (sorting of a total of 236 out of 300 articles produced from the search). In addition, a critical discussion deciphering the major challenges for the commercialization of these bioagents as biofertilizer, biostimulants, and biopesticides was undertaken to unlock the prospective research avenues and wider application of these natural resources. The advancement of biotechnological tools may help to enhance the sustainable use of bacterial biostimulants in agriculture. The perspective of biostimulants is also systematically evaluated for a better understanding of the molecular crosstalk between plants and beneficial bacteria in the changing climate towards sustainable soil and plant health.
