Rhizobacteria play a positive role as biocontrol agents well Plant Growth Promoting (PGPR) agents. The research objective was to obtain indigenous rhizobacteria isolates on cocoa plants that have the potential inhibit attack of P. palmivora fungal pathogens, and act PGPR in vitro vivo. results study concluded TRI 7/1, 8/8, GM 7/9 7/10 had highest ability growth pathogen. lowest disease severity...

to evaluate the effects of plant growth promoting rhizobacteria (pgpr) such as azotobacter chroococcum, azospirillum lipoferom and brasilence and pseudomonas fluorescens and nitrogen fertilizer from urea source on yield and yield components of maize (zea mays l.) double cross hybrids (dc 370), a field experiment was carried out in a factorial experiment (5*3) in rcbd with 4 replications. bacter...

Abstract Many agricultural researches have been performed to improve soil productivity. Nitrogen (N) and Phosphorus (P) are essential elements which are utilized by the plants in large amounts. Phosphorus can be provided by applying chemical fertilizers. Microorganisms convert insoluble phosphate to the soluble form and some bacteria such as rhizobacteria play an important role in this proces...

the caster bean oil is high value in industry around of world. plant nutrition and plant growth promoting rhizobacteria (pgpr) are important for crop production. an experiment was set up to investigate the effect of nitrogen (n), sulfur (s) fertilizers and pgpr on seed yield production of ricinus commines l. this experiment was carry out in factorial layout based on complete randomize block des...

Plant growth is influenced by a variety of abiotic and biotic factors. To survive a Complex and hostile environment, plants have evolved a series of inducible defense Mechanisms that enable them to activate appropriate defense responses upon Pathogen and abiotic stress factors attacking. Besides, rhizosphere bacteria also play a very important role in maintaining healthy plant growth process, s...

Numerous species of soil bacteria which flourish in the rhizosphere of plants, but which may grow in, on, or around plant tissues, stimulate plant growth by a plethora of mechanisms. These bacteria are collectively known as PGPR (plant growth promoting rhizobacteria).Of the microorganisms that parasitize on nematodes and reduce nematode populations by antagonistic behaviour, bacteria hold an im...

Soil salinity is one of the major abiotic constraints in agricultural ecosystems worldwide. High levels have negative impacts on plant growth and yield, affect soil physicochemical properties. Salinity also has adverse effects distribution abundance microorganisms. problems previously been addressed research, but most approaches, such as breeding for salt tolerant varieties amelioration, are ex...

Plant growth promoting rhizobacteria (PGPR) are known to influence plant growth by various direct or indirect mechanisms. Thirty–two strains were isolated from 15 soils sampled in central Iran, by using and comparing three different methods. The screening of soil samples by means of soil paste– plate method combined with isolation on mannitol agar proved to be the best strategy in terms of reli...

Abstract The increasing demand for agricultural products can be met by maximizing production potential and reducing crop losses caused common plant-parasitic nematodes. Chemical-based nematode management is a successful technique mitigating damage yield pests; however, inappropriate irresponsible application of synthetic pesticides has negative impacts on fauna, bioflora, natural enemies such a...
