Abstract

There are several ways of cultivating crops that are applied by the community, namely: monoculture, insertion and agroforestry. Differences in the application and management of cropping patterns and the types of plants planted will have a different effect on microbes in the rhizosphere, especially fungi as biological agents. The purpose of this study was to determine the types of fungal biological agents found in the rhizosphere of several plants with different cropping patterns on peatlands. The location of the samples was determined purposively with insert cropping patterns (mustard-sweet corn), mono-culture (sweet corn) and agroforestry (jelutung-soursop). Testing the inhibition of biological agent fungi against Sclerotium rolfsii used a completely randomized design consisting of 7 treatments with 3 replications. The exploration results obtained 7 isolates of biologically active fungi that could inhibit S. rolfsii. The highest inhibition was shown by isolates JSk1 (origin from the rhizosphere of soursop plants), isolates J (origin from the rhizosphere of sweet corn) and JS1 (origin of the rhizosphere of mustard greens). JSk1 and J isolates had an inhibition close to 60%. The results of the identification of JSk1 isolates were the fungus Gliocladium sp1, isolate J the fungus Trichoderma harzianum with competitive inhibitory mechanisms, mycoparasites, antibiosis causing host hyphae to experience malformation, lysis and destruction.

Abstract

Peatland is a specific ecosystem that is always waterlogged and has multiple functions, including economic, hydrological, environmental, cultural, and biodiversity functions. Existing peatlands, especially in Central Kalimantan, have great biodiversity potential. This potential provides benefits for people living in peat areas. This diversity of biodiversity has the potential of medicinal plants that have not been maximally explored. Therefore, through this activity, data will be obtained regarding the types and potential of medicinal plants in inland peat areas, which will facilitate their management. This research activity was carried out in the “Handak Maju” IUPHKm area for 3 (three) months, from July – September 2022. The implementation method is carried out through survey activities and field observations and carrying out of the Focus Group Discussions, as well as related literature studies. Based on the results of the survey conducted, it was found that several types of medicinal plants have the potential to be developed and preserved. According to Zuhud (1991) that medicinal plants are plants whose plant parts (leaves, stems or roots) have medicinal properties and are used as raw materials in the manufacture of modern and traditional medicines. It was further revealed that, medicinal plants are still not widely cultivated. However, the advantages of treatment using traditional medicinal plant ingredients are generally considered safer than the use of modern medicine. This is because traditional medicine has relatively fewer side effects than modern medicine.

Abstract

The aim of the research was to determine the effect of applying a consortium of Trichoderma spp. isolates to a type of organic fertilizer that is effective in controlling twisted disease and on the growth and yield of shallot plants. The study utilized a completely randomized design (CRD) consisting of eight treatments with four replications. The treatments examined werea= as follows: P0 = control, P1 = 5 tons per ha of chicken manure fertilizer, P2 = 5 tons per ha of chicken manure fertilizer and consortium of two Trichoderma spp. isolates, P3 = 5 tons per ha of chicken manure fertilizer and consortium of three Trichoderma spp. isolates, P4 = 5 tons per ha of chicken manure fertilizer, 20 tons per ha trichocompost, and a consortium of two Trichoderma spp. isolates, P5 = 5 tons per ha of chicken manure fertilizer, 20 tons per ha trichocompost, and consortium of three Trichoderma spp. isolates, P6 = 20 tons per ha of trichocompost and a consortium of two Trichoderma spp. isolates, and P7 = 20 tons per ha of trichocompost and a consortium of three Trichoderma spp. isolates. The results showed that the twisted disease incidence in treatment P4 was the lowest (14.52%) at 8 weeks after planting. The plant height was of 39.10 cm, with 29.8 leaves per clump at 7 WAP, and the dried bulb weight was 112.4 g per clump. In conclusion, the application of chicken manure fertilizer at a dose of 5 ton per ha, combined with 20 tons per ha of trichocompost and a consortium of two Trichoderma spp. isolates, could control twisted disease in shallot.

Abstract

This study aims to determine the inhibitory ability of antagonistic fungi from the rhizosphere of pepper (Piper nigrum L.), betel nut (Piper bettle L.) and Bawang Suna (Allium cinense G.Don.) against Fusarium oxysporum capsici which causes damping off disease and its effectiveness as a seed coating against damping off disease in chili seedlings. The research was carried out in the laboratory and experimental garden of the Department of Agricultural Cultivation, Faculty of Agriculture, UPR. Testing the antagonistic inhibition of F.o.capsici in vitro, where the antagonistic fungus with the highest inhibition from each plant rhizosphere was used as a seed coating for chili seeds to determine its effectiveness in suppressing damping off disease on seedlings. The results of the study obtained nine antagonist fungi with very good inhibition against the pathogen F.o.capsici in vitro ranging from 70.36 – 77.74%. Three types of antagonistic fungi that are used as active ingredients in seed coatings are Gliocladium sp. from pepper rhizosphere (73.53% inhibition), Penicillium citrinum from betel rhizosphere (77.74% inhibition), and Trichoderma harzianum from suna onion rhizosphere (70.83%). The seed coating treatment with active ingredients from three types of biological agents significantly reduced the intensity of damping off disease (0%) compared to the control (23.75%). Control effectiveness reaches 100% with very good category. Seed coating with active ingredients of T. harzianum and Gliocladium sp was able to increase plant height by 34.06% and 43.11%, respectively, but there was no significant difference in increasing the number of leaves. Seed coating treatment with biological agents effectively protects seeds and plant seedlings from attack by pathogens F.o. capsici through mechanisms such as antibiosis, parasitism and competition, besides that rhizosphere fungi can induce plant resistance and produce growth regulators which can increase the growth of chili seedlings. It is hoped that in the future the seed coating treatment added with biological agents can replace the use of chemical pesticides in controlling soil-infected diseases

Abstract

The purpose of this study was to study the effect of organic fertilizer on the growth and yield of GH-63 soybeans on inland peat. The peat used was taken from Kalampangan Village and the land conditions had never been used for agricultural cultivation. The study was conducted in the Peat Techno Park area of ​​Palangka Raya University. Using a Completely Randomized Design, with 4 treatments of Rhizoka compound organic fertilizer dosage, namely H0 = 0 g.kg seed-1, H1 = 10 g.kg seed-1, H2 = 20 g.kg seed-1, H3 = 30 g.kg seed-1. Each treatment was repeated 5 times and because there were destructive and non destructive observations, the study was conducted in 2 (two) equal series. Data were analyzed by analysis of variance at the 5% and 1% levels. If the results of the analysis of variance indicate a significant effect, it is continued with the BNJ test at the 5% level. The results showed that treatment H3 = 30 g.kg seed-1 as the best treatment in all parameters, namely leaf area (77.03 cm2), effective root nodule weight (1.015 g), root dry weight (1.04 g), loss dry weight (3.71 g), root extinction ratio (3.64 g), number of seeds (1.98 seeds) and seed weight (1.15 g) compared H0 = 0 g.kg seed-1. The dose dose of biofertilizer is 30 g.kg seed-1 as the best dose for the growth and yield of GH-63 soybean plants on inland peat.
