Abstract

Fusarium oxysporum f.sp capsici, which causes chili-fusarium wilt disease, may be regulated by a secondary metabolite of Trichoderma harzainum. Effervescent tablets are used because liquid formulations have some drawbacks. The purpose of this study is to qualitatively determine T. harzianum’s best crude secondary metabolites, growth and yield, and phenolic compound content in chili crops in foamed tablet formulations against F. oxysporum in vitro. The in vitro study used 6 replicates, a completely randomized design, and 4 treatments consisted of controls and 4, 6, and 8 tablets. Under in vivo conditions, the experiment used a randomized block designs with 4 replicates, eight treatments consisting of controls, fungicides (benomyl), and four, six, or eight tablets per day before or after inoculation. The variables observed were antagonist testing, incubation time, disease intensity, disease incidence, AUDPC, germination rate, plant height, root fresh weight, and qualitative phenolic composition. The results of the study showed that the best dose of T. harzianum’s crude secondary metabolite in vitro was 4 tablets. Medications in in-plant studies delayed the incubation period by 64.11%, suppressed disease outbreaks by 58.34%, reduced disease intensity by 80.45%, increased plant height by 50.4%, and harvested phenols (saponins, tannins, hydroquinone). The content of the compound has been qualitatively increased.

Abstract

This study aimed to screen and characterize halotolerant bacterial isolates, which could enhance plant growth performance in saline soil. Halotolerant bacteria was isolated from weeds rhizosphere grown in saline soil of coastal agricultural land located at Brondong District, Lamongan Regency, East Java Province, Indonesia. This research was conducted from June to September 2018. Seven bacterial isolates can grow in a Nutrient Agar medium containing 10% of NaCl, suggesting that these bacteria were halotolerant. Furthermore, all bacterial isolates were shown to produce indol acetic acid (IAA) and do not induce a hypersensitive response when infiltrated into tobacco leaves. These results explain that these bacteria had potency as plant growth-promoting rhizobacteria (PGPR) and were not tend to be the plant pathogen. The growth of seedlings when inoculated in cucumber seed grown in saline media were higher than those in control. This result suggests that the halotolerant bacteria can enhance the development of cucumber seedlings in saline stress conditions. Three potential halotolerant bacteria i.e., SN22, SN23, SN26 were selected and molecularly identified as Bacillus megaterium, Bacillus sp., and B. megaterium, respectively.

Abstract

The agroforestry system with its diversity of vegetation has the potential on the existence of antagonistic and entomopathogen fungi. This study was conducted to evaluate the diversity of antagonistic fungi and entomopathogen fungi in the rhizosphere and pine leaf litters on pine monoculture and intercropping pine - coffee. The research was started from plot determination, sampling, fungal identification, antagonist test and pathogenicity test. The results of isolation of fungi from pine leaf litter on monoculture pine and intercropping pine-coffee fields obtained 17 genus of fungi. In monoculture pine, there 9 genus of fungi were found, while other 4 were still unidentified. In pine-coffee intercropping land 13 genus were observed. Based on the potential and bility tests, Acremonium sp. 3 and Penicillium sp. 2 has the highest inhibiton capacity, while isolate Paecilomyces sp. 1 and Paecilomyces sp. 2 had the best level of pathogenicity and mortality. Temperature and humidity did not affect the diversity of fungi. The diversity of entompathogenic and antagonistic fungi was higher in the pine-coffee intercropping land use. The litter plots had higher fungal diversity than the rhizosphere.

Abstract

Colletotrichum gloeosporioides is the cause of anthracnose disease on mango. This disease becomes more damaging because it economically affects the harvested fruit during the postharvest season. In this research, eight isolates are isolated from the soil of a mango plantation. One of the isolates shows antifungal activity against C. gloeosporioides MC9. This isolate is identified as Penicillium citrinum isolate S1 based on the phylogenetic analysis of ribosomal rRNA sequence. From the culture of this isolate, extracellular filtrates are collected and evaluated for their antifungal activity. The mycelial growth of C. gloeosporioides is significantly inhibited by the culture supernatant of P. citrinum isolate S1. The culture filtrate is used to purify the antifungal protein using ammonium sulfate and ultrafiltration methods. Results show that the antifungal protein was estimated at around 40 kDa molecular weight when separated on a 10% Sodium dodecyl sulfate-polyacrylamide gel. After nine days of incubation, this antifungal protein’s inhibition effect with a concentration of 0.94 mg/ml remained 63.6% against C. gloeosporioides. The LCMS result showed that the antifungal protein belongs to the L-asparaginase superfamily. Based on this result, the antifungal protein produced by P. citrinum S1 has the potential to control mango anthracnose disease caused by C. gloeosporioides.

Abstract

Multiple cropping farming systems affect farmers' income and have become a serious determinant in agricultural development. The diversity of information received by the farmers including multiple cropping can provide new knowledge, which will in turn influence productivity and income. Therefore, this study aims to evaluate the benefits of multiple cropping and its economic impact on cocoa farmers' income. It was conducted using the Ordinary Least Square Method to estimate parameters and RC Ratio for income comparison from the farming systems. The results showed that the choice of farmers in cropping patterns and types of crops is aimed at avoiding crop failure. The advantage of multiple cropping is that the use of soil nutrients is more effective because plants grow together on the same land. It also provides a higher income compared to monocropping and tends to reduce operational costs. Among the five factors evaluated, only three influenced farmers' income through extension activities. They are information on credit amount obtained, level of heterogeneity, and agricultural production. These factors are important aspects of communication activities that can increase knowledge in a heterogeneous environment of multiple cropping systems, which will, in turn, improve farmers' income.

Abstract

Chili anthracnose caused by Colletotrichum spp. is a significant disease of chili cultivation in Indonesia. The current taxonomic status of Colletotrichum spp. has been rearranged due to a well-developed molecular study. Several species of Colletotrichum were re-identified after being analyzed by a polyphasic approach. The polyphasic method in this research combines morpho-cultural and molecular identification using ITS-rDNA and GADPH region. The pathogenicity test would be more reliable in identifying the species complexes of Colletotrichum that are difficult to differentiate. This study applies a polyphasic approach to identify Colletotrichum species causing chili anthracnose, especially in fruits collected from chili fields in Yogyakarta, Indonesia, and observe its pathogenicity in wounded and unwounded inoculation. The results of those combination methods showed that isolates collected from chili fields in Yogyakarta were C. scovillei. The pathogenicity test revealed that the fungus caused anthracnose disease in wounded and unwounded OR Twist 42 chili fruits. The unwounded infection was confirmed by amplification of the ChEC3 pathogenicity gene 24 h after inoculation, showing that appressoria production may possess an essential role in the unwounded inoculation. This study revealed that C. scovillei does not always need a wound for its pathogenicity

Abstract

The production of Brassica oleracea var. alboglabra (commonly known as baby kai-lan) with nutrient film technique can generally be performed in a relatively short period to get a high selling value of products. This study aims to determine the effect of several types of nutrients and growing media applications on the productivity and quality of baby kailan products. The research involves two test variables (nutrition and planting media) with three variations of plant nutrition and four kinds of growing media. The physical and morphological analysis results provide information on leaf width parameters. Concerning medium, perlite shows the best average yield in each plant variation. Regarding nutrients, product “Z” nutrition has the most substantial influence on the growth of the object of research. The physical and morphological tests show that the average number of leaves in almost all treatments is seven. However, the highest average number of leaves is achieved by treatments using perlite and hydroton growing media with planting nutrients “Z”. The edible weight of the harvest test shows that the treatment combination of perlite and nutrient “Z” has the highest average, i.e., 59 g per plant.

Abstract

Pineapple can be affected by fruit collapse, a disease caused by the bacterium Dickeya zeae. However, adequate fertilization can increase the fruit’s resistance to this illness. Therefore, the impact of preharvest foliar calcium and silicon fertilization on pineapple quality and fruit collapse incidence was assessed in this study. The experiment implemented a split-plot design with two factors. The first factor has two terms of inoculation (flower induction and before harvest). The second factor uses a control with three foliar fertilization treatments, A (control: No foliar fertilizers applied), B (Ca from 13 to 11 weeks before harvest/from 6 weeks to harvest), C (Si from 13 to 11 weeks before harvest/from 6 weeks to harvest), and D (Ca + Si from 13 to 11 weeks before harvest/from 6 weeks to harvest). Treatment D gave the best response. It had the lowest fruit collapse incidence (21.70%), highest ascorbic acid (71.64 mg/kg), elevated β-carotene (4.87 mg/kg) and mineral content (Ca: 1851.10 mg/kg, Si: 1164.87 mg/kg), essentially under the before harvest term of inoculation, which was more harmful for the fruit. In conclusion, mixed foliar calcium and silicon fertilization manage to improve the tolerance to fruit collapse incidence, impacting the pineapple quality positively

Abstract

Chemical insecticides are intensively used in agriculture which cause negative effects on environmental sustainability by increasing pest tolerance and continuous action on local fauna. In contrast to chemical insecticides, biological insecticides target specific pests, minimizing their impact on the surrounding environment. However, most of the natural insecticides available in the market are expensive for farmers in the Central Asian region. This study is the first evidence of the effectiveness of local entomopathogenic nematodes (EPN) from the arid zone of northern Kazakhstan that can be used as an alternative to export EPN products. The laboratory experiment is conducted with two local and two commercial Steinernema feltiae and Steinernema carpocapsae, which are applied to larvae of Tenebrionidae. The experiment design is randomized with four doses of EPN (100, 200, 300, and 400 IJ/cm2) and a control (without EPN). According to the experiment results, one out of two local EPNs (AF29 at dose 100 IJ/cm2) caused a high mortality rate (67%) among larvae. This finding confirms that local EPNs can compete with commercial EPNs and potentially be used as insecticidal agents.

Abstract

This research aims to determine the type of mulch material that effectively reduces the risk of erosion on agricultural lands and gives minimum detrimental impacts on water quality. The S12 Advanced Environmental Hydrology System used for rainfall simulator. Rainfall intensity was set up based on the daily annual maximum rainfall data. Meanwhile, the land slope is according to research site contour. This research was designed to compare the conditions of soil without mulch (WM) and Rice Straw Mulch (RSM), Mendong Biogeotextile Mulch (MBM), and Plastic Mulch (PM). The observed quality parameters were Dissolved Oxygen (DO), pH, and Total Dissolved Solids (TDS). Statistical analysis involved a three-way analysis of variance (ANOVA) with the aid of SPSS 26 software. Based on the smallest mean values for the amount of surface runoff discharge (mean 1.10), amount of sediment yield (mean 0.650), change in pH (mean 7.48), and TDS (mean 0.24) value, it can be concluded that MBM is the most optimal to be utilized as soil cover for agricultural lands. The performance of MBM is better than RSM and PM.
