Abstract

Fosfat merupakan salah satu unsur yang berperan penting bagi pertumbuhan tanaman dan kesuburan tanah. Namun, ketersediaan unsur P terlarut yang dapat diserap oleh tanaman sangat kecil karena berikatan dengan kation yang berada di dalam tanah. Salah satu upaya dalam meningkatkan P tersedia dalam tanah adalah dengan pemanfaatan agen hayati Bakteri Pelarut Fosfat (BPF). Penelitian ini bertujuan untuk menguji isolat BPF yang dapat meningkatkan kelarutan P dan pertumbuhan padi pada uji hayati. Percobaan ini dilaksanakan di Rumah Kaca Departemen Ilmu Tanah dan Sumber Daya Lahan, Fakultas Pertanian, Universitas Padjadjaran. Rancangan percobaan yang digunakan adalah Rancangan Acak Kelompok (RAK) dengan 6 perlakuan dan 5 ulangan. Masing-masing perlakuan jenis bakteri adalah kontrol, Bacillus substilis, B. megatherium, Pseudomonas mallei, Burkholderia sp., dan isolat campuran. Hasil percobaan menunjukkan isolat BPF yang diuji memiliki kemampuan yang bervariasi dalam meningkatkan enzim fosfatase, kelarutan P, dan pertumbuhan padi pada uji hayati. Lebih lanjut, perlakuan BPF campuran memberikan pengaruh lebih baik terhadap aktivitas fosfatase, P terlarut dan pertumbuhan padi dibandingkan isolat tunggal.ABSTRACTPhosphorus is an element that important for soil fertility and plant growth. However, the phosphate nutrient can be uptaken by plants only in a small amount because it binds to cations in the soil. The effort for enhancing the soil P availabilty is by the phosphorus solubilizing bacteria (PSB). This study aimed to test PSB  isolates  for increasing P solubility and rice growth using bioassay. The experiment conducted at the greenhouse in Jatinangor District, Sumedang Regency, West Java with  Randomized Block Design (RBD) for PSB isolates with five replications. Each type of bacteria treatment was control, Bacillus substilis, B. megatherium, Pseudomonas mallei, Burkholderia sp., and mixed isolates. The results showed that the P solubilizing  isolates had various abilities to enhance phosphatase, P solubility, and rice growth using bioassay. Furthermore, the mixed PSB isolates had a better effect on phosphatase activity, dissolved P and rice growth than single isolates.

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 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

Abstract

Climate change causes high waves on the seas that can accelerate the salinization of agricultural land located in coastal areas. Saline soil does not support plant growth because of the limitations of plant roots in absorbing water and nutrients, especially Nitrogen. Increasing salinization causes challenges in finding proper soil management methods, including nature-based solutions. A potential method to strengthen plant growth in saline areas is the introduction of biofertilizers containing nitrogen-fixing bacteria (NFB) that are resistant to salinity. This article aims to review the tolerance of nonsymbolic NFB Azotobacter to salinity and discuss the potential of this beneficial rhizobacterium for mitigating plant cultivation in saline land. The article was compiled through a literature study analyzing various relevant references from national and international journals in the last ten years. Analysis of the references shows that several soil Azotobacter strains are resistant to certain salt levels and have specific physiological characteristics when living in saline environments. Azotobacter induces plant tolerance to high salinity in the pot experiment. Therefore, Azotobacter inoculation becomes one of the alternatives to increase the growth of crops in saline soil.

Abstract

Long-term use of NPK composite fertilizers mixed with biofertilizers, including spore-forming Bacillus rhizobacteria, can improve plant quality and growth. This study aims to analyze Bacillus’s growth and spore production in chemical-liquid growing media and to observe the effects of Bacillus-coated NPK formulas (BCN) on the growth of tomatoes in potted Andisol and the Bacillus population in the rhizosphere. The evaluation of Bacillus growth was conducted in the laboratory whereas the effect of the BCN was conducted as a pot experiment in a Randomized Block Design. The treatments included recommended dosage of NPK 16-16-16, liquid inoculant of Bacillus consortium, BCN-C, and BCN-G formulas with 100%, 75%, and 50% of the recommended dosage, respectively. Control plants were not treated with fertilizer. Laboratory assay verified that Yuniarti’s medium supported Bacillus-consortium growth and produced the highest Bacillus vegetative cells and spores. The BCN application significantly increased plant height, number of leaves, root length, and tomato biomass compared to the control up to 6 weeks after planting. Three-quarters of the dosage of BCN-C and BCN-G gave the best growth of tomatoes. Introducing BCN and conventional NPK did not change the population of Bacillus vegetative and spore form in the rhizosphere. Results indicate that BCN can replace conventional NPK 16-16-16 fertilizer for tomato plants in Andisol soil order.
