Abstract:

One of the major challenges that the world is facing currently is the inadequate amount of food production with high nutrient content in accordance with the increase in population size. Moreover, availability of cultivable area with fertile soil is reducing day by day owing to ever increasing population. Further, water scarcity and expensive agricultural equipment have led to the use of agrochemicals and untreated water. Excessive use of chemical fertilizers to increase crop yield have resulted in deleterious effects on the environment, health and economy, which can be overcome to a great exte

Abstract:

Agriculture in the twenty-first century has several issues, including soil fertility, climate changes, environmental degradation, urbanisation & rising food consumption to feed the world's growing population. Meanwhile, scientists are grappling with major obstacles in expanding food yield from the present land base. Traditional farming has seen increased per-acre crop yields due to the haphazard and injudicious use of agrochemicals, such as pesticides and synthetic fertilisers, but at a significant environmental cost. Crop pests developing pesticide resistance is another big worry in moder

Abstract:

Plant Growth Promoter Rhizobacteria (PGPR) is soil bacteria that can live on, in or around plant tissue and promote plant growth by many mechanisms that include a biological control of plant pathogens. Indeed, PGPRs have a protective effect through several modes of action such as antagonism, competition, production of hydrolytic enzymes and biofilm formation. Moreover, the use of PGPRs as biocontrol agents is very harmonious with the environment and therefore represents a good alternative to the use of chemicals in agriculture.

Abstract:

Plant growth promoting-rhizobacteria (PGPR) contributes a significant part in crop health improvement including pest management. It also protects plants from parasitic nematodes damage by exhibiting biocontrol activity besides improving the growth of plants by supplying nutrients, producing phytohormones and inducing modification of plants metabolisms. PGPR decreases or inhibits the hatching of nematode juveniles and suppresses the nematodes development and reproduction by exhibiting various mechanisms such as hyperparasitism, antibiotic synthesis or antibiosis, substrate competition, synthesi

Abstract:

Sweetleaf stevia (Stevia rebaudiana Bertoni) is one of the potential sugar-producing plants besides sugar cane which is widely used as a natural non-calorie sweetener. Propagation of stevia by shoot cuttings produces more uniform seedlings. Plant Growth Promoting Rhizobacteria (PGPR) contains a group of beneficial bacteria that live in the plant root ecosystem that can stimulate plant growth. This study aims to determine the effect of PGPR on the growth of stevia cuttings and the best concentration of PGPR on the growth of stevia cuttings. This study was conducted in February-May 2024 in Kolon

Less than half of the applied chemical fertiliser in intensive cropping systems is utilised by the target crops, with the remaining nutrients contributing to environmental pollution. Reducing the pollution derived from inefficient use of chemical fertilisers has enormous importance for agriculture. Recently, studies have shown that plant growth promoting rhizobacteria (PGPR) Paraburkholderia sp.

Plant-growth-promoting rhizobacteria (PGPR) influence soil fertility, plant growth, tolerance to abiotic stress, resistance to herbivorous insects, and plant interactions with other organisms. While the effects of PGPR on plant growth, fruit yield, and induced defense responses have been extensively studied, the consistent positive outcomes have fueled rapid expansion in this research field. To evaluate PGPR impacts on plant growth and interactions with phytophagous insects, we conducted a systematic meta-analysis using publications from electronic databases (e.g., PubMed, Web of Science) that

Abstract Plant growth-promoting rhizobacteria (PGPR) are non-pathogenic, soil-inhabiting, beneficial bacteria that colonize the roots of plants. Some PGPR strains are reported to increase nutrient uptake and fix atmospheric N, which suggests that biofertilization with PGPR may provide an alternative to N fertilization for forage production. In mid-August 2017, a study was initiated to evaluate PGPR as an alternative form of N fertilization for fall-stockpiled bermudagrass. Eighteen 1-m2plots were mowed to a 2.5-cm stubble height prior to stockpiling. Two strains of PGPR (Blend 20 and DH44) wer

Abstract:

Plant growth-promoting rhizobacteria (PGPR) enhance plant development by many mechanisms. Indirect growth effects result from PGPR activities that displace soilborne pathogens and thereby reduce disease. Direct effects include improved nutrition, reduced disease due to activation of host defenses, and bacterial production of phytohormones. An understanding of the mode of action is essential for exploitation of PGPR for field use. For instance, bacteria that act as biological control agents can only be of benefit at locations where disease occurs. PGPR that stimulate plant growth directly will
