Plant growth-promoting bacteria (PGPB) have become an important subject of research to increase maize production. The PGPB consortium should provide more benefits than single or dual inoculation. This study aimed to investigate the effect of a PGPB consortium on improving maize growth and yield. The field experiment used a split-plot design. The main plot consisted of three maize varieties (Talenta, Pertiwi-3, and Bisma), and the subplot consisted of three formulations of PGPB consortia [endophytic bacteria isolates, Acetobacter sp., cellulolytic, and ligninolytic (F1); endophytic bacteria isolates, Azospirillum sp., cellulolytic, and ligninolytic (F2); and endophytic bacteria isolates, cellulolytic, ligninolytic, Acetobacter sp., and Azospirillum sp. (F3)] and one control. PGPB consortia formulation did not influence maize growth significantly, but maize varieties did. Pertiwi-3 showed the highest value in all growth variables, followed by Bisma and Talenta, respectively. The effect of PGPB consortia formulation upon ear fresh and dry weight depends upon the maize variety, and Pertiwi-3 showed the highest value in yield variables. PGPB consortia formulation 2 was the most effective to apply for Pertiwi-3 cultivation, while PGPB consortia formulation 3 produced higher yields for Talenta and Bisma. These findings indicated that specific PGPB formula could improve the yield for specific maize varieties.

“…The application of rhizobacteria enhanced vegetative growth, which was triggered by the ability of rhizobacteria to produce auxins, especially indole acetic acid (IAA) (Chitra & Jijeesh, 2021;Chauhan et al, 2021). The ability of rhizobacteria to produce IAA will stimulate root elongation so that the root surface area that interacts with soil colloids increases and results in increased nutrient and water uptake (Purwanto et al, 2017;Purwanto et al, 2019;Rahma et al, 2019). Rahma et al, (2019) stated that the increase in root growth through the expansion of the root system was stimulated by hormones, thereby increasing nutrient uptake caused by the ability of rhizobacteria to dissolve nutrients such as P. Rhizobacteria can increase the availability of nutrients in the soil (N,P, K) so that nutrient uptake (N, P, K) increases, thereby increasing photosynthetic pigment and activity (Chauhan et al, 2021).…”

The growth and yield of plants are strongly influenced by the early growth ability of the plants. Similar germination and good seed vigor will greatly support plant growth and increase production. Increasing the germination and vigor of seeds can be done through biopriming. The application of biopriming using rhizobacteria is developing environmentally friendly agricultural technology. This study aimed to determine the effect of inoculation of rhizobacteria from the north coast of Pemalang on rice plants' germination and vigor index. The study was arranged in a Randomized Block Design, consisting of 10 treatments with three replications. Ten rhizobacteria isolates were isolated from the North Coast of Pemalang, Central Java, consisting of Ju1, Jn3, Jn1, J, J12, J5, Kn1, A3, Jn, and K3. The biopriming with rhizobacteria isolated from the rice rhizosphere of the Northern Coast of Pemalang increased the seed germination rate, seed vigor index, and early vegetative growth of rice seedlings. Inoculation with isolate J12 produced the highest vigor index of 8280.01. The results of this study imply that the application of rhizobacteria from saline soil has the potential to increase the vigor of rice seedlings to impact better seedling growth in saline conditions.

The most significant challenges facing farmers and plant producers worldwide are minimizing or neutralizing the impacts of environmental pressures on agricultural plants, safeguarding against pests and diseases, and simultaneously maintaining optimal plant growth and development. The environment and raising food quality standards require minimizing using of chemicals fertilizer. Plant growth-promoting rhizobacteria (PGPR) have the ability to promote plant growth through a range of mechanisms, both direct and indirect. These mechanisms include mineral solubilization, phytohormone and siderophore synthesis, and the utilization of extra secondary metabolites and enzymes. PGPR have a prospect in biofetilizer can improve the effectiveness of fertilization.
