Abstract

Mass production media of biofertilizer must be able to maintain the shelf-life in accordance with provisions of the Regulation of the Minister of Agriculture Number 01 of 2019 concerning Organic Fertilizer, Biofertilizer, and Ameliorant. This paper review aims to provide an overview of the media of mass production Azotobacter biofertilizer in Indonesia. Azotobacter biofertilizer in the form of a single liquid or solid fertilizer must have a minimum population of 1x108 CFU/g. Isolation of the nitrogen fixer microbe Azotobacter can be carried out through one or more agroecosystems, after that grown at selective media, pick the carrier either liquid or solid carrier, and additive that can increase microbial viability. Liquid carriers have more advantages over solid carriers. Before commercializing, it is necessary to check the quality of the biofertilizer referring to applicable regulations.

Abstract

AbstractPresent study aimed to perform literature review to investigate the current status and potential use of plant growth promoting rhizobacteria (PGPR) for enhancing the soil plant’s health, plant growth and productivity in sustainable ways. The Systematic Literature Review (SLR) methods was applied according to Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) on published scientific literature from 2012-2022. Results revealed that genus diversity of PGPR (Bacillus sp., Serratia sp., Streptomyces sp., Pseudomonas sp., and Burkholderia sp.) produce siderophore and phytohormones such as indole-3-acetic acid (IAA), gibberellin (GAs), auxin, and 1-aminocyclopropane-1-carboxylic acid (ACC) deaminase activity, organic acids, biocontrol agent that contribute to the improvement of nutrient bioavailability (nitrogen fixing, phosphate solubilizing and Fe-uptake). The growth character of rice inoculated with biofertilizer and combined with 50% inorganic fertilizer produced no significant difference with pots that received 100% inorganic fertilizer. These results concluded that PGPR that produced phytohormone and siderophore could be developed as a potential bioagent or biofertilizer to improve the growth character and yield of upland rice (Oryza sativa L.) in dry environmental conditions.Keywords: PGPR producing phytohormone and siderophore, N2-fixer, Biofertilizer, Systematic review AbstrakKajian tinjauan pustaka ini dilakukan untuk menyelidiki status saat ini dan potensi penggunaan rizobakteri pemacu pertumbuhan tanaman (PGPR) untuk meningkatkan kesehatan tanah, pertumbuhan tanaman, dan produktivitas secara berkelanjutan.

Abstract

The fruitfulness of biofertilizer application in increasing plant growth and yield is when the formulation uses selected microbial isolates that do not cause disease to plants. Hypersensitivity test is carried out to ensure that the microbial isolates used in the formulation of biofertilizer are not pathogenic to plants. The purpose of this study was to determine the pathogenicity of three selected potassium solubilizing bacteria (KSB) isolates (BPK-DHJ3-3150[17], BPK-DHJ1-4125[2], and BPKDHJ2-5250[16]) isolated from the maize plant rhizosphere on Inceptisols Jatinangor. The research was conducted using a qualitative experimental method that obtained data in the form of visual photos. The three selected KSB isolates were inoculated on tobacco leaves and observed for necrosis symptoms. The experimental results showed that the three selected KSB isolates did not cause a positive hypersensitivity reaction in tobacco leaves, which was indicated by the absence of necrosis symptoms at the leaf location where the KSB isolates were inoculated. The three KSB isolates were nonpathogenic isolates to plants.

Abstract

Rice is an important commodity in Indonesia because rice is the main source of carbohydrates for the Indonesian. Rice production in Indonesia relies on lowland rice, but the productivity of lowland rice is decreasing. One of the efforts to increase rice national production is utilizing upland rice plants. The problem with upland rice is its low productivity. Nitrogen-fixing biological fertilizers can be used to increase the productivity of upland rice plants. The effect of different doses of nitrogen fertilizer and nitrogen fixing bacteria with different carrier materials on the growth and yield of upland rice in Inceptisols Jatinangor was studied. Randomized block design with two factors: the recommended dose of urea fertilizer (100% and 50%) and the nitrogen-fixing bacteria factor with different carriers (compost, rice bran, and Azolla powder) were applied as an experimental design. The experimental results showed that the interaction of nitrogen fertilizer dose and nitrogen-fixing bacteria with different carriers had no significant effect on plant height, number of panicles, root shoot ratio, and weight of 1000 grains of upland rice plants. Application of nitrogen-fixing bacteria with compost, bran, and Azolla powder as carriers was able to increase the average weight of the filled grain higher than the control.

Abstract

Acidity is still a serious obstacle for maize cultivation due to the very low availability of phosphorus. The use of phosphate biofertilizers, containing phosphate solubilizing bacteria as an active ingredient, together with organic ameliorants was expected to be able to provide phosphorus for plants, increase the organic C content in the soil. Experiment aimed to find the proper application of phosphate biofertilizers along with organic ameliorants to support the growth and yield of maize on acid soils. The experiment used a factorial randomized block design with phosphate biofertilizers and organic ameliorants as the first factor and doses of P fertilizer as the second factor, which was repeated three times. Results showed that the application of phosphate bifertilizers consisted of Enterobacter ludwigii + Bulkholderia vietnamiensis + Citrobacter amalonaticus were applied together with organic ameliorants with the composition of chicken manure compost (25%): municipal waste compost (25%): coconut shell biochar (50%) at a dose of 5 tons/ha was able to increase plant dry weight and dry weight of shells per hectare by 248.87 g and 12.960 kg. The C-organic content of the soil had no significant effect due to the application of phosphate biofertilizers and organic ameliorants. The application of phosphate biofertilizers and organic ameliorants can support the growth and yield of corn plants on acid soils.

Abstract

Utilization of saline land as an effort to increase rice productivity is still constrained by the adverse effects of salinity stress. The solution to this effort can be done by utilizing PGPR biofertilizers and applying ameliorant briquettes. The purpose of this study was to evaluate the effect of using biofertilizers and ameliorant briquettes on saline soils with various levels of salinity on the growth of rice plants. This research was conducted at the Ciparanje Jatinangor screen house from September 2022 to January 2023. The research design used was a randomized block design with 12 treatments and 3 replications. The treatment applied was PGPR biofertilizer, ameliorant briquettes, and their combination on saline soil 4 and 8 dS m-1 compared to control (non-saline soil). The results showed that PGPR biofertilizer increased the height of rice plants on saline soils 4 and 8 dS m-1 7 DAP. At 14 DAP, PGPR biofertilizer, ameliorant briquettes, and their combinations did not increase rice plant height, root length and volume, wet weight, and dry weight of rice plants, although the application of biofertilizers, ameliorant briquettes, and their combinations tended to increase wet weight and dry weight of rice plant compared to soil with the same salinity without biofertilizers and ameliorant briquettes.

Abstract

Intensive use of inorganic fertilizers causes damage to soil ecosystem and environment. While, the utilization of biofertilizers holds significant potential in enhancing soil health and increasing crop yields as a viable solution for achieving more sustainable agricultural practices. This literature review explores biofilm biofertilizers (BBF) and plant growth promoting rhizobacteria (PGPR), examining their applications in improving soil-plant health, growth, and productivity. Employing Systematic Literature Review (SLR) methodologies, scientific literature from 2012 to 2022 was analyzed following PRISMA guidelines. Reputable journals indexed in Google Scholar and E-Journal Springer were selected, and relevant keywords were used to gather primary references. Results demonstrate that PGPR from various genera (Serratia sp., Bacillus sp., Pseudomonas sp., Streptomyces sp., and Cyanobacteria) produce growth promoters like indole-3-acetic acid (IAA), gibberellins, ethylene, and cytokinins. Combining BBF with chemical fertilizer can reduce chemical usage by up to 48%, reducing reliance on them. BBF containing PGPR exhibit potential to enhance agronomic of food crops traits and promote sustainable farming practices in Indonesia.Keywords: Systematic review, Biofilm, Biofilm Biofertilizer, Sustainable farming, Indonesia

Abstract

Selecting a carrier material compatible with microbes is crucial for ensuring the quality of biofertilizers. This research aimed to identify a carrier material that could sustain the population of inoculants from dryland (including Delftia tsuruhatensis strain D9, Delftia sp. strain MS2As2, and Bacillus sp.) for a specified period. After conducting the study, it was found that a formulation of 3% molasses, 3% glycerol, 1% potassium sorbate, and 1% Tween-20 enriched with 1% nutrient was the most effective carrier material in maintaining the number of live inoculant cells. This formulation was able to sustain the population of inoculants up to the twelfth week, with a total population of 21.60 × 108 CFU.mL-1 with pH value of media is 5.29, and fulfilled the main criteria for biofertilizers.

Abstract

Farmers usually apply more chemical fertilizers to enhance the yield of strawberries in soilless culture. Humic substances and biofertilizers are now considered essential nutrient sources in sustainable agriculture. The objective of the greenhouse experiment was to observe the effect of humic and fulvic acid (humic substances), and biofertilizer on root growth, nitrogen (N) and phosphor (P) of the growing media, populations of N-fixing and P-solubilizing bacteria in the root zone, and yield of strawberry grown in the cocopeat-based substrate. The experiment was set up in a randomized block design consisting of seven treatments and four replications. The treatments included humic acid, fulvic acid, and biofertilizer in single or combined applications. All data were subjected to analysis of variance and followed by Duncan's Multiple Range Test with p<0.05. All treatments received 50% of the recommended dose of NPK fertilizer. The results showed that all treatments did not affect root length and dry weight. Mixed application of humic substances and biofertilizer together with NPK fertilizer increased total N and P as well as the population of N-fixing bacteria in the growth substrate. Still, P-solubilizing bacteria did not grow in the cocopeat-based substrate. Moreover, mixing humic substances and biofertilizer increased strawberries' fruit yield and sweetness levels.
