Plant rhizospheric zone is a narrow soil region were rich in microbes. Microbes are of capacity to dissolve phosphate. Phosphate (P) is the second essential component after N, which plays a crucial part in photosynthesis and root development. P is difficult to dissolve due to strong bonding with compounds in the soil. Here, we explored rhizospheric bacteria around chili peppers’ roots area. The bacteria were isolated and purified on solid media. The bacterial isolates were then quantitatively… 
Production of IAA hormone in rhizosphere bacterial isolates of community forest stands
The rhizosphere is the soil around plant roots, which is directly affected by soil microbes, and exudation of plant roots have an essential role in plant health and soil fertility. The IAA (Indole
Potency of Plant Growth Promoting Rhizobacteria (PGPR) in Ipomea pes-caprae roots: Initial microscopic and macroscopic identification on South Sulawesi’s coastal resources
The paper reports on an initial study aimed to isolate and identify plant growth promoting rhizobacteria in the roots of Ipomea pes-caprae (locally named as Katang-katang) abundantly found in the
Response of chili (Capsicum annuum L.) to bioslurry fertilization and enrichment of Trichoderma asperellum on planting media
This study aimed to determine the response of chili plants (Capsicum annuum L.) to the treatment of bioslurry fertilizer and enrichment of Trichoderma asperellum on planting media. The study was
Improvement of growth of common bean in phosphorus-deficient soils by phosphate-solubilizing and phytohormone-producing bacteria
The use of phosphate fertilizers is generally required for normal growth and development of crops. The cost of manufactured phosphate fertilizers has increased drastically in recent years and these
Response of tomato plant on various concentrations and application frequency of gibberellin
This study aimed to determine the production of tomato plants with the application of gibberellin growth regulators. This research was conducted at the Experimental Farm, Faculty of Agriculture,
Comparative cost analysis of pepper farming income under certification and non-certification seeds implementation (Case in Towuti District, East Luwu Regency, South Sulawesi Province, Indonesia)
Certification is an activity to foster farmers about good and correct cultivation in accordance with agreed standards to improve quality and ask farmers to care for the environment, which then
Isolation of phosphate solubilizing bacteria from the rhizosphere of local aromatic rice in Bada Valley Central Sulawesi, Indonesia
Phosphate Solubilizing Bacteria (PSB) can be used to increase the efficiency and availability of P in the soil as it can help the process of releasing the bound of P elements so that they become
Effect of Trichoderma and tofu waste based organic fertilizer on the fruit development of chili (Capsicum annuum L.)
The study aimed to determine the effect of the application of Trichoderma and liquid organic fertilizer from tofu wastes on the growth and production of large chilli plants (Capsicum annuum L.). The
Growth and production of Katokkon (Capsicum chinense Jacq) chili plants in lowland applied with gibberellins and liquid organic fertilizer
This study aimed to determine the growth and production of katokkon chili plants (Capsicum chinense Jacq.) in the application of gibberellins and liquid organic fertilizer. This research was


Gibberellin And IAA Production by Rhizobacteria From Various Private Forest
Rhizobacterium is a bacterium that colonizes plant roots, known to produce gibberellin and Indol Acetic Acid (IAA) to spur plant growth. This study aims to isolate rhizobacteria from various stands
Genetics of phosphate solubilization and its potential applications for improving plant growth-promoting bacteria
Preliminary results achieved in the engineering of bacterial strains for improving capacity for phosphate solubilization are presented, and application of this knowledge to improving agricultural inoculants is discussed.
Gibberellic acid, a metabolic product of the fungus Gibberella fujikuroi: Some observations on its production and isolation
From a selected rice-infecting strain of Gibberella fujikuroi a plant-growth-promoting substance has been isolated in pure form, distinct in chemical properties from the gibberellins described by Japanese investigators.
Gibberellin production by bacteria and its involvement in plant growth promotion and yield increase
This review focuses on studies with bacteria for which biosynthesis/production of the plant hormones gibberellins have been demonstrated and the potential involvement of symbiotic and soil-endophytic microorganisms in plant growth promotion and yield increase.
Rock phosphate solubilization with gluconic acid produced by immobilized Penicillium variabile P16
Penicillium variabile P16 immobilized on polyurethane sponge produced gluconic acid in presence of rock phosphate, the latter being simultaneously solubilized during five repeated batches. A total
