Abstract

Aspergillus parasiticus, the causative agent of Aspergillus cob rot, and Mucor circinelloides, which causes Mucor stem rot, are types of pathogenic fungi that have the potential to reduce the quality of corn (Zea mays L) harvests. An effective and environmentally friendly approach to control these pathogens is to use biological agents, such as Trichoderma harzianum. This study aims to evaluate the inhibitory potential of T. harzianum against A. Parasiticus and M. circinelloides using antagonism tests with dual culture methods in vitro. The parameters used in this study were measurements of the percentage of the inhibition rate of the biological agent T. harzianum against pathogenic fungi. The results of the antagonism test showed that the biological agent T. harzianum had moderate inhibition against A. parasiticus and M. circinelloides with the percentage of each inhibition during the five days incubation period are 32.5% and 42.38%. This indicates that T. harzianum has the potential as a biological agent in controlling A. parasiticus and M. circinelloides in corn plants.

Abstract

Shallots have physiological and pharmacological effects on the human body and have been cultivated intensively using biocompost, which may be contaminated with heavy metals. Enrichment of arbuscular mycorrhizal (AM) fungi in biocompost and the addition of biological organic fertilizer (BOF) to reduce the absorption of heavy metals in shallot bulbs is the main objective of this research. The study used a Randomized Block Design with five treatments, namely: shallots cultivation method by indigenous farmers/control(B0); Dose of biocompost enriched with AM fungi 100kg plot-1(B1); 200kg plot-1(B2); 100kg plot-1+BOF(B3); 200kg plot-1+BOF(B4), has been carried out in Enrekang district, South Sulawesi by observing the components of heavy metal content in plant organs and the level of infection of AM fungi in plant roots. Results showed that a dose of biocompost enriched with AM fungi 200 kg plot-1, and 100kg plot-1+BOF could increase Cr, Cu, and Pb accumulation in roots and leaf, as well as reduce metal accumulation in shallot bulbs, with level AM fungi infection classified as very high. The novelty of this study is that organic fertilizer enriched with AM fungi can reduce the absorption of heavy metals that accumulate in shallot bulbs and is essential information for farmers.

Abstract

The high industrial demand for mint products, coupled with low domestic production, has led to a 63% import dependency. Enhancing mint production requires optimizing planting media and fertilization strategies. This study aimed to evaluate the effects of different soil-to-husk charcoal ratios and manure types on the growth and yield of mint (Mentha spicata L.). A factorial experiment was conducted from February to April 2022 at the Faculty of Agriculture, UNS, using a randomized complete block design (RCBD) with two factors: The first factor was soil-to-husk charcoal ratios consisting of 1 to 3, 1 to 1, and 3 to 1. The second factor was the manure type, which consisted of cow, goat, and chicken manure. Each treatment was replicated four times. The results showed that the P1 combined with the cow manure significantly increased the number of branches compared to P1 with goat manure. P1 also resulted in the highest number of leaves, leaf area, fresh weight, and dry weight. Cow manure yielded the highest values for leaf number, leaf area, and dry weight among manure treatments. These findings suggest that optimizing planting media composition and manure selection can enhance mint productivity, reducing reliance on imports.

Abstract

This paper discusses the development and acceptability of Mead wine flavored with Dragon Fruit. A Quantitative Descriptive Analysis Survey was utilized among forty (40) panelists who are experts in alcohol while 75 respondents were randomly selected as participants in the sensory analysis using a Hedonic rating scale with a 5-point Likert scale. The results of the study have shown that the product was acceptable considering its color, aroma, taste and even the alcohol content of both treatments. In the findings, the highest responses on color is ruby with 62.5%, responses on aroma are regarded as sweet, tangy and even zesty nuance. The taste reveals that it is fairly acceptable with a 2.30 mean, which accounts for its acidity and good for food pairing. On the overall acceptability level of the three coded samples, wine coded control got the highest description of high acceptable and a mean of 4.38. While in the willingness to purchase the product, commercial product got the highest mean of 4.13, acceptable and wine with code treatment 1 got a high score of 4.03, also acceptable. The results of this study imply that mead with added dragon fruit has the potential to produce mead that is preferred by respondents.

Abstract

Acid soil is widely available in Indonesia and is suboptimal, so yields are low. The research examines the effect of antagonism and nitrogen fertilizer on peanuts' growth, nodulation, and yield in sour planting. This study used a factorial complete randomized block design with two factors. The first factor is the dose of Nitrogen fertilizer with four levels: 0, 50, 100, 150 kg.ha-1. The second factor is the source of rhizobium with three levels: without rhizobium, legin rhizobium dose ten g.kg-1 seed, and rhizobium from peanut plantations. They were repeated three times. Nitrogen 50 kg.ha-1 with the source of used peanut rhizobium showed the highest plant height, 15.73 cm. The combination of 100 kg.ha-1 of nitrogen with a source of used peanut rhizobium showed the highest number of plant leaves, namely 675.33 leaves. A nitrogen dose of 50kg.ha-1  produced the highest effective number of nodules and nodules, namely 363.00 and 19.33 nodules. The optimum nitrogen fertilizer dose is 44 kg.ha-1 for nodule growth. 50 kg.ha-1  nitrogen dose produced the highest number of pods and seed weight, namely 48.67 pods and 407.79 g of seeds. Nitrogen fertilizer at the correct dose can increase peanuts' growth, nodulation, and yield in acid soil. However, a dose that is too high may cause antagonism with the nodulation process and reduced yield.

Abstract

Peat formation is the main key to carbon sequestration in the Peat Swamp Forest (PSF). The research aims to analyze alternative possibilities for peat formation based on the available soil nutrients and dried biomass. In a complete randomized block design, a factorial trial was applied using two treatment combinations in three blocks: factor A (sampling plots, land cover) and Factor B (dried biomass). Data were analyzed using two-way ANOVA and Tukey Honestly Significant Difference test at a significance level of 5%. A high supply of dried below-ground biomass did not follow the production of rooting litter at high soil nutrients. Most of the biomass was transported upwards into above-ground biomass. All land covers produced above-ground biomass which had the potential to form peat with significant differences for all parameters studied. The potential for peat formation was highly dependent on the various types of land covers (e.g. peat forest), environmental factors, the composition of the seed bank, and the species ability to compete. Restoration actions (revegetation, rewetting, and revitalization) aim to stimulate the development of peat-forming species. The research benefits are expected to enrich PSF's ecological restoration thinking so that PSF can be restored and returned to near its initial condition.

Abstract

Shallots are indispensable in all aspects of human life, and shallot production is always facing Fusarium wilt disease. Chemical control of the disease has failed, and environmentally friendly control alternatives are needed. One of them is Bio P60 biocontrol product combined with liquid organic fertilizer. Aims of the research was to assess the effectiveness of NASA liquid organic fertilizer and Bio P60 in controlling Fusarium wilt and its impact on shallot growth and yield in planta. This research was conducted in the field using polybag, for five months. Completely randomized block design was used comprising of two components with 16 treatments and 3 replicates. The variables observed were incubation period, disease intensity, AUDPC, plant height, number of leaves, number of tubers, plant wet weight, tuber wet weight, plant dry weight, and tuber dry weight. The results showed that the application of Bio P60 five times was the most excellent treatment in postponing the incubation period by 61.71%, suppressing disease incidence by 66.67%, and reducing AUDPC by 69.84%, increase growth and yield components such as plant height by 30.75%, number of leaves by 40.7%, number of bulbs by 75.6%, bulb fresh weight by 104.53%, blub dry weight by 51.1%, crop fresh weight by 48.24%, and crop dry weight by 49.77% compared to the control. The fertilizer application has no significant effect on all variables. There was no interaction between Bio P60 and NASA on all variables.
