Abstract

Mercury (Hg) is a hazardous pollutant produced during the amalgamation of gold extraction. The environmental problems related to improper Hg waste management have become progressively concerning. Hg contamination in environments can be removed by using bioremediation technology. Utilizing Hg-resistant (HgR) microorganisms in Hg bioremediation is a crucial strategy. Azotobacter is one of the potential microbes for Hg bioremediation bioagent due to exopolysaccharides synthesis that binds the heavy metal. The study's main objective was to select and profile a novel Hg-resistant Azotobacter isolated from heavily Hg-contaminated soil and tailing of artisanal and small-scale gold in Pongkor area, West Java, Indonesia. The completely randomized design was used for profiling Azotobacter-HgR and included Hg values of 0, 1, 10, 100, 200, and 400 mg/L. Further, Azotobacter isolate bioassay steps included soil contaminated with Hg, soil contaminated with Hg + Azotobacter sp. S6.a, soil contaminated with Hg + consortium. The profiling results revealed that four Hg-resistant isolates were Azotobacter sp. S5, Azotobacter sp. S6, Azotobacter sp. S6.a, and Azotobacter sp. S9. More importantly, Azotobacter sp. S5 followed by Azotobacter sp. S6.a was found to be the most resistant to Hg exposure at a concentration of 400 mg/L. The Azotobacter sp. S9. produced the lowest EPS, but had the highest activity of nitrogenase and organic acid production. Meanwhile, Azotobacter sp. S6.a. produced the highest EPS. Isolate S5 showed the highest potential as a resistant PGPR-Hg isolate for enhancing the growth of sorghum in Hg-contaminated soil. Sorghum plants accumulate Hg from the soil in the roots but not in the shoots. Present findings suggest that these two isolates have the potential to be used as biological agents to rehabilitate Hg-contaminated soil in Pongkor area.

Abstract

Limestone mining removes topsoil and produces overburden piles, which is improper for plant growth. The objectives of this study were to compare the texture, certain chemical properties, and bacterial population of overburden to the topsoil and to observe the effects of compost amendment on the growth of corn seedlings on the potted overburden. The overburden characterization was performed using a quantitative descriptive method with purposive sampling. Samples were taken from a 6-month-old overburden pile and a pine-vegetable agroforestry ecosystem. The data were further analyzed by using the Student’s t-test. A bioassay was set up in                            a randomized block design with various concentration compost treatments and five replications. The results showed significant differences between texture, chemical characteristics, and bacterial counts of overburden and topsoil were recorded. The topsoil was more acidic and had higher organic carbon, potential phosphorus, potential potassium, and cation exchange capacity, while the overburden had higher levels of calcium; however, the total N and Magnesium content in topsoil and overburden was similar. The bacterial population of the overburden was lower than in the topsoil. A total of 16 gram-negative and one gram-positive bacteria have been identified from both samples. Applying huge amounts of compost enhanced corn seedlings' growth in the overburden. The study suggested that overburden was more unfertile compared to the topsoil. Therefore, the improvement of overburden properties by compost amendment is needed to green the area.

Abstract

Soil compaction has been recognized as a form of soil degradation that mostly deteriorates agricultural soil health worldwide from various climatic conditions and soil management. Heavy compaction can occur in agricultural soils due to intensive tillage, where its effects on soil properties have been the focus of many studies. The present study was undertaken to assess whether soil compaction occurs in agricultural soils adopting no-tillage systems and how the link between soil compaction and chemical-biological characteristics could be. A field investigation was carried out in two different locations that have different soil types, Entisol in Maitara Island and Ultisol in Halmahera Island, North Maluku Province. Sixteen undisturbed and disturbed soil samples were collected from each location grown with cassava and taken to the laboratory for analysis. Soil components observed included soil texture, bulk density, particle density, total porosity, soil permeability, soil organic matter (SOM), total nitrogen (N), phosphorous (P) availability, and phosphate-solubilizing bacteria (PSB). The findings revealed linear relationships between soil compaction and sand fraction, SOM, PSB, and available P, but none were found in soil total N. These results confirmed the importance of soil compaction management in food crop agricultural systems, particularly when soil carbon is low, to promote soil health. As the inconsistent correlation of soil compaction and chemical-biological properties was found in these two soil types, further investigation is necessary.

Abstract

The Aster (Callistephus chinensis L) is an important commodity and is cultivated by using NPK fertilizer. The other nutrient source in environmental-friendly agriculture is biofertilizer contains mixed strains of beneficial microbes. The purpose of a field experiment was to observe the influence of various biofertilizer composed of mixed strain of Nitrogen-fixer bacteria and Phosphate-solubilizer microbes on Aster plant growth and yield of flower. The research design was a randomized block design consisted of four biofertilizer types and one control. The results verified that biofertilizer increased plant height at 9 weeks after application but have not affected the initial generative stadia. The consortia of Pseudomonas diminuta, P. Cepaceae, Penicillium sp., and Aspergillus sp. showed the best effect on the plant health, flower number per plot, and flower diameter. The experiment confirmed that all biofertilizers could be used as the source of biostimulants for Aster.

Abstract

The Nutrient Film Technique (NFT) in hydroponic crop production systems generally uses chemical nutrient solutions to provide plant nutrients, even though biofertilizer inoculation can enrich liquid nutrients. The purpose of this experiment was to observe the effect of liquid biofertilizers applied with chemical nutrient solutions on changes in the acidity and electrical conductivity of nutrient solutions, as well as the growth and yields of pak choy (Brassica rapa L.) grown in Nutrient Film Technique. This experiment was set up in a completely randomized design with three nutrient solution treatments and eight replications. The treatments included the application of 100% chemical nutrient solution (control), and 75% and 50% concentrations of chemical nutrient solution enriched with a consortium biofertilizer. The results showed that at the end of the experiment, the acidity of all nutrient solutions increased, but their electrical conductivity (EC) was reduced. The fresh weight of pak choy shoots in medium B (75% chemical nutrition with biofertilizers) was 34% lower than the control (A), although statistically it was not significant. However, 50% chemical nutrition with biofertilizers produced the same shoot weight as the recommended dose of chemical nutrition. Moreover, 75% chemical nutrient with biofertilizers increased root weight. This current experiment verified that a reduced concentration of nutrient solution enriched with biofertilizer can be used to maintain the yield of pak choy grown in NFT.

Abstract

Nitrogen-fixer and phosphate-solubilizer bacteria increase the chemical-fertilizer efficiency and soil health. Bacterial-coated NPK fertilizer is a novel approach for intensifying biofertilizer application in vegetable production. The study aimed to observe the compatibility between two Azotobacter species and two Bacillus species, their population on two formulations of bacterial-coated NPK fertilizer (BCN), and the effect of BCN dose on growth, N and P content, and their uptake in tomato shoots. The compatibility test was performed using the streak method. The population of Azotobacter and Bacillus were counted for two formulations of NPK fertilizer coated by solid biofertilizer (5% and 10%) and zeolite (1% and 5%). The pot experiment was conducted in a randomized block design with four treatments and six replications. The treatments were 100% recommended doses of conventional NPK fertilizer (700 kg/ha) and 100%, 80%, and 60% doses of BCN. The results showed four bacterial species were compatible, indicated by synergistic growth on the plate agar. The BCN formula using 5% liquid inoculant and 5% zeolite has higher cell viability. The BCN enhanced stem thickness and leaves number but did not change the plant height, dry weight, N and P content, and their uptake in shoots. Applying 60% of BCN caused greater stem thickness and leaf number. Despite being insignificantly different from another treatment, that dose increased the biomass and the shoot uptake of N and P. The NPK fertilizer coated by Azotobacter and Bacillus has the potency to increase tomato growth and NPK fertilizer dose.

Abstract

The impact of tailings accumulated on agricultural land is the loss of soil profile and decreased soil quality, making plants difficult to grow. This study aimed to observe the effect of cow dung manure (CM) doses to gold mine tailings on total fungal and bacterial populations of soil surrounding roots and water spinach biomass and to analyze the correlation between fungal and bacterial populations with water spinach growth parameters. The experiment was designed in a randomized block design with five treatments and five replications. The treatments included without CM (control) and 5, 10, 15, and 20% of CM in tailing. Similar treatments were added to plants grown in mineral soil, i.e. Inceptisols. The results determined the retarded plant growth in tailing compared to that in Inceptisols. The plant grown in tailing was more responsive to manure amendment. The CM increased total fungal and bacterial populations in the soil around the roots, plant height, leaf number, stem thickness, wet weight, and dry weight of intact plants. Applying 5% of CM caused better growth of water spinach than other treatments. Total fungal and bacterial populations were strongly correlated with water spinach height and dry weight. ABSTRAK Dampak negatif penumpukan tailing di lahan pertanian adalah hilangnya profil tanah dan penurunan kualitas tanah sehingga tanaman sulit tumbuh. Penelitian ini bertujuan untuk mengobservasi pengaruh pemberian dosis pupuk kotoran sapi (PKS) pada tailing tambang emas terhadap populasi jamur dan bakteri total biomassa kangkung darat (Ipomoea reptans (L.) Poir.) serta menganalisis korelasi antara populasi jamur dan bakteri di tanah sekitar perakaran dengan parameter pertumbuhan kangkung. Percobaan pot di rumah kaca disusun dalam rancangan acak kelompok dengan lima perlakuan dan lima ulangan. Perlakuan percobaan adalah tanpa dan dengan penambahan 5, 10, 15 dan 20% PKS ke dalam tailing. Perlakuan yang sama diberikan pada tanaman kangkung dengan tanah Inceptisol. Hasil percobaan menunjukkan bahwa pertumbuhan kangkung di tailing terhambat dibandingkan di tanah Inceptisols, tetapi tanaman di tailing lebih responsif terhadap aplikasi PKS. Pupuk kotoran sapi mampu meningkatkan populasi jamur dan bakteri total di sekitar perakaran, tinggi tanaman, jumlah daun, ketebalan batang, bobot basah serta bobot kering tanaman di tailing. Pemberian 5% PKS lebih meningkatkan pertumbuhan tanaman kangkung dibandingkan dengan perlakuan lainnya. Populasi jamur dan bakteri masing-masing berkorelasi positif dengan hubungan yang sangat kuat dengan bobot kering serta tinggi tanaman kangkung. Percobaan ini menjelaskan bahwa bahan organik penting untuk memperbaiki kualitas tailing dan pertumbuhan tanaman.

Abstract

Gold-mine tailings, challenging environment for plant growth, was our study focus. Introducing nitrogen-fixing bacteria (NFB) and phosphate-solubilizing bacteria (PSB) provides nutrients and phytohormones for plant growth. A pot experiment was designed to assess the corn growth on tailing inoculated with NFB and PSB. The research, conducted in a completely randomized block design, was replicated seven times; the treatments were : without inoculation (control), single inoculation of Azo-7.2, single inoculation of BPF-9, a mixture of Azo-7.2 and BPF-9. The results revealed that inoculation of NFB and PSB significantly increased plant height, stem diameter, leaf number, and P-uptake but did not affect leaf area, chlorophyll content, root length, S/R ratio, N-uptake, and plant biomass, and NFB and PSB count in the rhizosphere. Single inoculants of BPF-9 and mixed inoculants increased plant height by 1.2% to 7%, stem diameter, leaves number, and S/R ratio; only mixed inoculation increased N-uptake, however, Azo-7.2 potential to enhance leaf area, chlorophyll content, and corn biomass. The population of NFB and PSB in the rhizosphere of all treated and control plants was slightly lower than the initial population. The research, in particular, verified that the corn growth on tailings inoculated with NFB and PSB was better than that of uninoculated. ABSTRAK Tailing tambang emas yang merupakan tantangan untuk pertumbuhan tanaman, menjadi fokus penelitian ini. Inokulasi bakteri pengikat nitrogen (BPN) dan bakteri pelarut fosfat (BPF) menyediakan nutrisi dan fitohormon yang penting untuk pertumbuhan tanaman. Percobaan pot dirancang untuk mengevaluasi kinerja pertumbuhan jagung (Zea mays L.) pada tailing yang diinokulasi dengan BPN dan BPF. Penelitian dilakukan dengan rancangan acak kelompok yang diulang sebanyak tujuh kali; perlakuan percobaan adalah tanpa inokulasi (kontrol) dan dengan inokulasi tunggal BPN Azo-7.2 dan BPF-9 serta campuran Azo-7.2 dan BPF-9. Hasil penelitian menunjukkan bahwa inokulasi BPN dan BPF dengan nyata meningkatkan tinggi tanaman, diameter batang, dan jumlah daun tetapi tidak mempengaruhi luas daun, kandungan klorofil, panjang akar, biomassa tanaman, serta jumlah BPN dan BPF di rizosfer. Inokulan tunggal BPF-9 dan inokulan campuran campuran meningkatkan tinggi tanaman 1,2% sampai 7%, diameter batang, jumlah daun, dan rasio S/R secara signifikan. Namun Azo-7.2 berpotensi untuk meningkatkan luas daun, kandungan klorofil, dan biomassa jagung. Populasi BPN dan BPF di rizosfer seluruh tanaman yang diberi perlakuan dan kontrol sedikit lebih rendah dibandingkan populasi awal sebelum percobaan. Penelitian ini, secara khusus, memastikan bahwa performansi pertumbuhan jagung pada tailing yang diinokulasi dengan BPN dan BPF lebih baik dibandingkan dengan tanaman di tailing tanpa inokulasi.

Abstract

Biofertilizer inoculation is a novel and sustainable approach for reducing chemical fertilizer dose. The nitrogen-fixing Azotobacter is a prominent rhizobacteria used in biofertilizer formulation. A field experiment was aimed to observe the N availability, N uptake, nodulation, and growth and yield of groundnuts grown with A. chroococcum liquid inoculant and reduced dose of NPK fertilizer. The field experiment was arranged in a Randomized Block Design to test eight combination treatments of A. chroococcum inoculant doses (2 and 3 L/ha) and NPK fertilizer doses (75, 150 and 300 kg/ha). Azotobacter and NPK application did not affect plant height at two and three weeks after sowing. Groundnuts treated with 2 L/ha Azotobacter combined with 150 kg/ha NPK had more NO3- in soil, N uptake, and root dry weight; its pod number and weight per plot increased 110% and 40% than that in plot received 2L/ha Azotobacter and 300 kg/ha NPK respectively. The experiment found that A. chroococcum shall replace part of NPK fertilizer for growing groundnut in Inceptisols soil order.

Abstract

The increase in corn plant growth is greatly influenced by cultivation techniques includingfertilization. However, the use of inorganic fertilizers for a long period of time can reduce soil quality.An alternative environmentally friendly technology that can substitute for the use of inorganicfertilizers is the biological fertilizer of nitrogen-fixing endotypic bacteria. These endophytic bacteriahave benefits as growth stimulants for plants in increasing nitrogen supply through N2 fixationthrough the air. This study aims to increase the growth of corn plants through the application methodand type of nitrogen-fixing endophytic bacteria. This study used a Randomized Block Design (RBD).The treatment of types and application methods consisted of treatments without endophytic bacterialisolates, endophytic bacterial isolates Gluconacetobacter diazotrophicus Corrig, G. diazotrophicusstrain 4L, and Burkholderia gladioli with three application methods, namely seed treatment, soiltreatment, and their combinations. The results of the study showed that G. diazotrophicus 4L bacteriaapplied by seed and soil treatment gave the best effect on the growth of corn plants on the parametersof the endophytic bacterial population in leaf tissue, wet weight and dry weight of corn by 1 and 3times compared to the control and there was also a tendency to increase the dry and wet weight of thecorn plant crown
