The influence of plant-growth-promoting bacteria (Azospirillum brasilense and Pantoea dispersa) on sweet pepper plants (Capsicum annuum L.) under limited N supply was studied. Inoculation did not affect leaf CO2 assimilation, Ci/Ca (the ratio of the intercellular to the ambient CO2 concentration), concentration of chlorophylls, chlorophyll fluorescence (maximum quantum efficiency of PSII) or SPAD readings. Total plant dry weight was significantly reduced in both inoculated and non-inoculated plants when the N supply was reduced from 12 (control) to 7 mM, whilst the NO3− and total-N concentrations in the leaves were not significantly affected by inoculation. Inoculation did not affect marketable fruit yield or the pigments (chlorophylls, lycopene and β-carotene) and carbohydrate (sucrose, glucose and fructose) contents in the fruits but flavonoids and anthocyanins were increased significantly by the addition of the bacteria, relative to non-inoculated plants under limited N supply. Key words: Plant-growth-promoting bacteria, Capsicum annuum L., soilless, photosynthesis, chlorophylls, flavonoids

Plant Growth Promoting Bacteria Rhizobacteria (PGPR) is one of the potential bacteria to enhance of Capsicum annuum through inhabitation the growth of pathogenic fungi. This study aimed to characterize PGPR in chili plants (Capsicum annuum). PGPR was isolated from the soil habitat of the red chili plant in Cilegon, Indonesia. Screening was then carried out with the dual culture method on Petri dishes and tested through in vivo method on the red chili plant. The selected bacteria were characterized morphologically, biochemically, and physiologically. The results revealed that there were 14 single isolates of bacteria from the roots of the red chili plants. The five single bacterial isolates, namely Azostobacter, Azospirillum, Pseudomonas, Serratia, and Beijerinckia have good potential as PGPR based on multiple culture screening by producing clear zones and positively effect the growth of chili plants.

Tall fescue (Festuca arundinacea) is a useful alternative to ryegrass in New Zealand pasture but it is slow to establish. Naturally occurring beneficial bacteria in the rhizosphere can improve plant growth and health through a variety of direct and indirect mechanisms. Keywords: rhizosphere, endorhiza, auxin, siderophore, P-solubilisation
