Abstrak. Salah satu perkebunan di Indonesia menghasilkan kakao (Theobroma cacao L.), yang memberikan kontribusi signifikan terhadap perekonomian dan cadangan devisa Indonesia. Masih terdapat tantangan dalam pengembangan seluruh Indonesia, termasuk Provinsi Aceh, antara lain adanya penyakit hama berkontribusi rendahnya produktivitas kakao. Penelitian ini bertujuan adalah untuk mendapatkan isolat...

Phosphorus (P) is one of the most important elements required for crop production. The ideal soil pH its absorption by plants about 6.5, but in alkaline and acidic soils, consumed P forms an insoluble complex with calcium, iron, aluminum availability plant decreases. supply needed mainly achieved through chemical fertilizers; however, addition to high price these fertilizers, long run, their de...

Abstract In the present study, potential of Alternanthera spp and its associated rhizobacteria to uptake biodegrade methylparaben (MP) under hydroponic conditions was assessed. The experiments were conducted in vitro using glass reactors 500-mL volume. results indicated that removal rates significantly higher (66.6±3%) than control (<40%). MP reduction data fitted well a first-order kinetics...

Selected strains of nonpathogenic rhizobacteria can reduce disease in foliar tissues through the induction of a defense state known as induced systemic resistance (ISR). Compared with the large body of information on ISR in dicotyledonous plants, little is known about the mechanisms underlying rhizobacteria-induced resistance in cereal crops. Here, we demonstrate the ability of Pseudomonas fluo...

Plant growth promoting rhizobacteria (PGPR) have been extensively employed as biofertilizers to enhance the soil nutrition for several crop plants. Rhizobacteria with beneficial effects plants could therefore be used reduce dependence on synthetic chemical fertilizers in conventional agriculture. Within this study, we explored isolation of potential PGPR groundnut from agricultural fields Saura...

Non-host resistance (NHR) is a broad-spectrum plant defense. Upon colonizing on the surface on the root or leaves of non-host species, pathogens initial encounter preform and induce defense response in plant, such as induced hypersensitive response, PAMPs triggered immunity (PTI), and effector triggered immunity (ETI). The ability of plants to develop an induced systemic response (ISR) in react...

Azospirillum is a rhizobacterial genus containing plant growth-promoting species associated with different crops worldwide. Azospirillum brasilense strains exhibit a growth-promoting effect by means of phytohormone production and possibly by N2 fixation. However, one of the most important factors for achieving an increase in crop yield by plant growth-promoting rhizobacteria is the survival of ...

Plant growth promoting rhizobacteria (PGPR) mediate the soil processes such as decomposition, nutrient mobilization, mineralization, solubilization, nitrogen fixation and growth hormone production. Microorganisms having the phosphate solubilizing capacity can convert the insoluble phosphates into soluble forms through the production of organic acids. Inoculation of seed with P-solubilizing micr...
