Abstract

The superior seeds are indicated by clean, good germination rate, pest and disease-free. One of the problems in providing superior tomato seeds is the presence of pulp attached to the tomato seeds, leading to less clean of seed. To remove the muscus on tomato seeds, the seeds have to be extracted. Other than seeds extraction, seeds exposure also could optimize seeds growth by increasing the metabolism of the tomato. The aim of this research is to determine the best extraction technique and magnetic field exposure for obtaining high tomato seeds germination. The complete random design used in this research consist of two factors, seeds extraction and magnetic field with three time replications. The result showed that seeds extraction for 24 hours is the best treatment for improving the maximum germination percentage, growth potential, growth rate, speed growth, uniformity index than others. Magnetic exposure at 6mT is the best treatment to improve seeds maximum growth and seeds speed growth.

Abstract

Urea fertilizers and biofertilizers play an important role in potato (Solanum tuberosum L.) cultivation, but urea fertilizers are volatile and leach out easily that reduce their effectiveness. Urea coated with beneficial bacteria-enriched organic matter is expected to increase nitrogen used efficiency. The purpose of the experiment was to determine the ability of bacterial-coated urea (BCU) included Bacillus and Azotobacter to improve the growth, nutrient status and yields of potatoes grown in field; as well as to reduce urea dose. The experiment was setup in randomized block design with five treatments and six replications. The treatments were four combinations of the dose and formulation of BCU; and conventional urea fertilizer as control treatment. Application of both BCU formulation increased plant height as well as N and P uptake particularly when the recommended dose was used.  In contrast, the doses and formulation of BCU did not affect chlorophyll content. Application of BCU-A or BCU-B at the rate of 200 kg/ha increased tuber weight by 59% and 81% respectively.  Both high and low dose of BCU did not reduce the vegetative growth and yield compared to the plants fertilized with conventional urea. This experiment showed that BCU is considered to reduce the rate of Urea in potatoes cultivation.

Abstract

Soil fertility is recognized as a crucial factor in supporting plant growth and productivity. The utilization of biofertilizers as environmentally friendly fertilizers is aimed at enhancing soil fertility and plant productivity. This study aims to explore the potential of local material for developing local wisdom biofertilizers (LWB) for achieving sustainable agriculture. A systematic literature review was conducted using bibliometric analysis, Preferred Reporting Items for Systematic Reviews, and Meta-Analyses (PRISMA) method, employing the Scopus search engine with the keywords "local AND wisdom AND biofertilizer" OR "biofertilizer" OR "local AND microorganism" OR "soil AND health OR crop AND productivity OR sustainable agriculture". The search yielded 704 articles, of which 11 were deemed eligible after selection. Based on the literature review, it was found that there are local materials, including fish waste, seaweed, Azolla, fruit waste, Moringa oleifera, microalga, bamboo roots, banana hump, golden snail, mangrove leaves, fruit, and vegetable waste that can be used as raw materials for LWB to improve soil health, plant growth, and productivity. The development of LWB as a new fertilizer technology faces challenges such as lack of regulations, low public trust, limited farmer awareness, weak promotion, and raw material shortages. Further research is needed to intensively study and enhance the effectiveness of LWB through enrichment using beneficial microorganisms.

Abstract

High concentration of salt in saline soil inhibits plants to grow normally. Good management of this soil may improve this land to be more productive. Utilization of indigenous beneficial soil microorganisms such_ as arbuscular mycorrhizal fungi (AMF) isolated from saline soil has been known to be able to increase plant growth and mycorrhizal sporulation. This study aimed to explore indigenous AMF species in saline soil, in West_ Java. This research was conducted in salt impacted areas in the northern coastal area of West Java i.e. Karawang, Subang, Indramayu, and Cirebon. The method used for soil sampling is by transect with the length of ordinate point in every 500 m of the coastline. The number of AMF spores, mycorrhizal colonization, and mycorrhizal species identification were analyzed. The result showed that the number of indigenous AMF spores per 25 g soil were 109 in Karawang, 50 in Indramayu, 170 in Subang, and 100 in Cirebon. The average mycorrhizal colonization was 90 %. Glomus sp. and Gigaspora sp. were found to be dominant in those soils. This result implies that some mycorrhizal fungi can live and maybe had good adaptation in saline soil and from symbiosis activity with the plant. Therefore they are the potential to evaluated and used to improve saline land productivity in the future.

Abstract

Intensive use of inorganic fertilizers has led to soil degradation, decreased productivity, and increased greenhouse gas emissions. Humic acid (HA) offers a sustainable solution by improving soil health and nutrient uptake while reducing dependence on chemical inputs. However, commercial HA from leonardite is expensive and rarely available in Indonesia. This study aimed to develop a high-quality and cost-effective HA product from low-rank coal (LRC) mined in South Sumatra. Given LRC’s low calorific value and high organic content, it presents an underutilized but promising HA source. A descriptive quantitative approach was used, starting with LRC selection and modified extraction to obtain HA. Laboratory-scale characterization revealed that locally sourced HA shares many functional groups with commercial leonardite-based HA. Hydrofluoric acid pretreatment significantly increased HA yield from 26.3% to 44%. A field trial was conducted on degraded soil overused with inorganic fertilizers, using a completely randomized block design with five treatments and five replications. Red chili (Capsicum annuum L.) was selected because of its high economic value. Data were analyzed using ANOVA at a significance level of 5%. The results showed that the combination of HA derived from LRC with low phosphate fertilizer (150 kg ha-1 SP-36 + 27 kg ha-1 HA) significantly increased plant height, fruit yield, and soil P availability, resulting in a yield of more than 28 t ha-1. These findings demonstrate the potential of LRC as a sustainable HA source to restore degraded soils and increase crop productivity in Indonesia.

Abstract

Enhancement of productivity of potato plants grown on poor-P soil such as Inceptisols due to application of arbuscular mycorrhizal fungi (AMF) has been acknowledged. However, whether this AMF improved the quality of potato tubers is still need further investigation. This study was conducted to evaluate the effectiveness of AMF in enhancing potato quality and determine whether the addition of compost and biochar to soil can support the productivity of this biofertilizer in enhancing the nutrient content in the tubers of potato plant. Screen house experiment was set up in factorial design with treatments were organic matter types (compost and compost plus biochar), and application of arbuscular mycorrhiza (without and with AMF consisted of Glomus sp. and Gigaspora sp.). Results of experiment showed that there was no interaction effect between organic matter and AMF on quality of potato tubers, however, the individual treatment especially AMF  increased the content of protein and lipid of potato tubers. Biochar that added to soil with compost was also increased the lipid content of potato tubers. This finding showed that AMF application in potato production grown in poor P-soil was not only increased the yield of potato, but also increased the quality of potato tubers.

Abstract

This research aimed to study the addition of ameliorant material in the soil to increase fertility rates, especially for potato plants grown at the height of 750 m above sea level. The experiments were conducted on medium plains 750 m above sea level in the Jatinangor area, Indonesia, with land type Incepticol. The composition of ameliorant consists of Cattle manure, biochar from coconut shells, and dolomite. The seeds of the potatoes used are relatively good varietal when cultivated in a medium plain. The design of the environment used is the group’s random draft repeated three times, the treatment design consists of K0: control; K1: Cattle manure 10 Mg ha-1; K2: Cattle manure 20 Mg ha-1; K3: Cattle manure 8 Mg ha-1, dolomite 1 Mg ha-1, 1 Mg ha-1 biochar; K4: Cattle manure 16 Mg ha-1, dolomite 2 Mg ha-1, 2-Mg biochar ha-1, K5: Cattle manure 8 Mg ha-1, dolomite 2 Mg ha-1; K6: Cattle manure 16 Mg ha-1, dolomite 4 Mg ha-1; K7: Cattle manure 8 Mg ha-1, biochar 2 Mg ha-1; K8: Cattle manure 16 Mg ha-1, biochar 4 Mg ha-1. Results showed that the composition and dose of ameliorant could increase the value of soil pH but have not improved the C/N ratio and absorption of phosphorus plants. The best result was obtained from the composition treatment of 16 Mg ha-1 Cattle manure, 2 Mg ha-1 dolomite, and 2 Mg ha-1 biochar. Soil pH is capable of increased by 16.83%, and the size of the potato bulbs of Class L (450-550 mm) amounted to 35, 11%, size M (350-450 mm) by 25.89%, and size S (200-350 mm) amounting to 34.37% when compared with controls.

Abstract

Low soil fertility was a major factor limiting national black soybean productivity. Black soybean, a functional food crop rich in isoflavones, requires effective fertilization to enhance growth.Environmentally friendly alternatives such as vermicompost and biofertilizers offer sustainableoptions. This study aimed to evaluate the effects of vermicompost and biofertilizers on rootcolonization by arbuscular mycorrhizal fungi (AMF), phosphorus (P) uptake, and black soybeangrowth, and to identify the most effective treatment. The experiment was conducted from December2024 to February 2025 in a plastic house at Bale Tatanen, Faculty of Agriculture, UniversitasPadjadjaran, Jatinangor, West Java. A Randomized Group Design with 12 treatment combinations andthree replications was used. Treatments consisted of 5 and 10 tonnes ha⁻¹ of vermicompost combinedwith either AMF or nitrogen-fixing bacteria (NFB), which were appllied to the planting holes. Datawere analyzed using ANOVA and the Scott-Knott test at a 5% significance level. Observed parametersincluded AMF root colonization, P uptake, plant height, number of leaves, chlorophyll index, leaf area,and dry weights of roots and shoots. The results showed that vermicompost and biofertilizersincreased AMF colonization, P uptake, plant height, leaf number, chlorophyll index, and shoot dryweight. The application of 5 tonnes ha⁻¹ vermicompost combined with AMF was the most effectivetreatment. This study provided useful recommendations for vermicompost and biofertilizerapplication to support soil fertility improvement and black soybean growth on marginal lands.
